4. Principle of measurement
Based on the photometric measurement of light scattered by the milk sample. Light is scattered by fat globule acting as small prisms and proteins. Not only fat globules in the milk contribute to light scattering,but also the proteins may affect the measurement. To elliminate this EDTA solution is used to dissolve this.

5. The range of globule size is limited in milk tester is 0.5 to 1.5 microns. Light rays from photo lamp passed through layer of fluid in cuvette and are scattered. More the fat present in cuvette ,more light scattered and less light passes through the cuvette. The rays passes to photo cell,produces current propotinal to light intensity.current is fed to digital read out which gives fat percentage.

6. Photometer & parts
Photometer->it consists of lamp,lamp housing & detector assembly.detector assembly includes cuvette and photocell. Cuvette->it is made up of 2 hardened glass discs.one has ground depression of 0.4mm & other has 2 holes which provides inlet and outlet to cuvette. Photocell->it is selenium barrier\silicon detector photocell. Lamp->12 volts tungsten lamp.

7. Procedures
Diluent->it is used to dilute the milk samples & dissolve the proteins. Repeatability->it is used to check that instrument is in proper working order , as leaks & poor connections will affect repeatability. Calibration->the purpose of calibration is to adjust the instrument to give results in 2 steps one gives correct linearity, other gives correct results.

 4. WHAT DO U UNDERSTAND BY COMMUNICATION ….?
Communication is a process of transferring information from one entity to another. Communication processes are sign-mediated interactions between at least two agents which share a repertoire of signs and semiotic rules. Communication is commonly defined as "the imparting or interchange of thoughts, opinions, or information by speech, writing, or signs".

 5. Types of Communication Systems
Analog Communication Systems Analog message: “Physical quantity that varies with time” Digital Communication Systems Digital message: “Ordered sequence of symbols selected from a finite set of discrete elements”

6. Telephone Exchange
In the field of telecommunications, a telephone exchange or telephone switch is a system of electronic components that connects telephone calls.

7. Electronic Exchange
Pre-digital automatic exchanges. To overcome demerits of traditional exchanges, electronic exchanges are used. The greatest advantage it provides is that no time is lossed in making a connection and a very high speed of operation is possible.

8. How the telephone call is made…??
Outgoing Calls Generally 48-60V always remains on the telephone line. But as the handset is picked-up the voltage limiter drops this voltage to 9-12V. On hearing the dial tone it is confirmed that the apparatus is ready to work and after dialing the number a ringing pulse is send to the called party. When the calling party picks-up the handset the billing meter of the exchange becomes activated. There is a counter in the exchange, which counts the pulse and converts them into calls.

9. Incoming Calls
Just opposite of outgoing calls. In the incoming calls the telephone detects the ringing signal from the exchange and provides the ring. At the instance of ringing signal, there remains a voltage of 75-110V/20 Hz on the telephone. A high voltage (A.C.) is sent from the ringer section of the exchange to start the ringer circuit of the telephone. The duration of this tone, if unattended, is 1 minute after which an engage tone is heard. After lifting the handset a circuit is established and a call is made.

A computer network is defined as having two or more devices (such as workstations, printers, or servers) that are linked together for the purpose of sharing information, resources, or both.

5. Local-Area Networks (LANs)
A local-area network (LAN) can connect many computers in a relatively small geographical area such as a home, an office, or a campus. It allows users to access high bandwidth media like the Internet and allows users to share devices such as printers.

6. Local-Area Networks (LANs)
The general shape or layout of a LAN is called its topology. Topology defines the structure of the network. This includes the physical topology which is the actual layout of the wire or media, and the logical topology which is how the media is accessed by the hosts.

7. Wide-Area Networks (WANs)
A WAN, as the name implies, is designed to work over a larger area than a LAN. A WAN uses point-to-point or point to multipoint, serial communications lines. Point-to-point lines connect only two locations, one on each side of the line. Point-to-multipoint lines connect one location on one side of the line to multiple locations on the other side.

8. Wide-Area Networks (WANs)
Connections across WAN lines may be temporary or permanent. Telephone or dialup lines, might make a temporary connection to a remote network from a computer in a home or small office. In both temporary and permanent cases, computers that connect over wide area circuits must use a modem or channel service unit/data service unit at each end of the connection.

9. Common Networking Devices

DTH Presentation Transcript:
1. How does DTH network work?
In simple terms the service provider broadcasts the signal that is sent to the satellite that then transmits the signal back to earth which is picked up by your dish antenna and fed to your television set.

2. WHY DTH SECTOR?
 DTH is a very attractive sector, on growth front, it has huge opportunities and companies will act aggressively to garner subscribers as it happened in mobile space. Only 5 million homes have DTH connections out of 75 million cable households in India. This is a positive aspect for this sector.

3. Some of the features of DTH
service are as following: DTH offers better quality picture than Cable TV. DTH can reach remote areas where terrestrial transmission and cable TV have failed to penetrate. DTH has also allows for interactive TV services such as movie-on-demand , and e-mail. In DTH, the payments will be made directly by the subscriber to the satellite company offering the service.

4. India currently has 6 major DTH service providers and a total of over 5 million subscriber households. Tata group and Star network owned Tata Sky Zee group owned Dish TV Sun network owned SUNDIRECT DTH. Reliance owned BIG TV Bharti Airtel’s DTH  DD Direct Plus India - DTH Potential DTH to grow from 3.2 mn in 2007 to 43 mn by 2015, with 30% share of Pay TV

5. COMPANY ANALYSIS -
A Birds view of Tata Sky: Tata Sky launched its services pan-India in August 2006. It resulted as a joint venture between the TATA group and the STAR group. It has over 147 channels to choose from Tata Sky recently launched Tata Sky Plus which uses the personal video recording (PVR) technology that allows consumers to record live.

6. Few salient features of the Tata Sky are:
Strongly innovative product offerings . Kick started the category advertising. Focus on heritage. Low cost packages to increase penetration. Tata Sky is collaborating with HUMAX and THOMSON to increase availability of Set Top Box. Tata sky, in order to increase its rural penetration, has tied up with ITC e-Choupal and Godrej Aadhar For Effective distribution Tata Sky has tied up with ITC international Business Division

7. KEY FACTORS OF GROWTH FOR TATA SKY:
The 3 major reasons for growth of Tata Sky that can be explored are: a) SUPERIOR PICTURE QUALITY Unlike analog cable, Tata Sky subscribers can view TV through superior digital DVD quality picture and CD quality sound. b) WIDE ARRAY OF INTERACTIVE APPLICATIONS In order to empower the Indian viewer with choice, control and convenience Tata Sky has a wide array of programming choices and interactive services like Active Cooking. c) UNPARALLELED CUSTOMER SERVICE Tata Sky has established an extensive customer service network across the country.

8. PRICING:
The prices of the key brands in the category are as follows: • The price per month of Tata sky (South Jumbo Pack - Rs. 310) is less than that of Dish TV . Number of channels that Tata Sky is providing (128) is more than the number of channels being provided by Dish Tv (119). Tata Sky also provides cost saving economic packages like family and Value packs.

 9. Set Top Box Technology
The basic Set Top Box (STB) takes the signal from the satellite dish and converts it into a signal that can be used by a TV, sound amplifier, etc. STBs can act as a gateway between a television or PC and telephone, satellite , terrestrial or cable feed. The analog STB receives encoded/compressed digital signals from the signal source and decodes/decompresses those signals. converting them into analog signals displayed on your analog television. The STB also accepts commands from the user and transmits these commands back to the network operator.

Advanced Optical Networks Presentation Transcript:
1. What is DWDM
Dwdm is the dense wavelength divison multiplexing It is the tecnology which multiplexes multiple carrier signals on a signal optical fiber is called the Dwdm Wdwm is the increces of the banwidth of the channel this tecnolgoy is called the Dwdm

2. Introduction to DWDM
DWDM systems being deployed today can increase a single fiber’s capacity sixteen fold, to a throughput of 40 Gb/s. Dense wavelength-division multiplexing (DWDM) revolutionized transmission technology by increasing the capacity signal of embedded fiber. DWDM technology can be applied to different areas in the telecommunication networks, which includes the backbone networks, the residential access networks, and also the Local Area Networks (LANs).

3. In the dwdm are three areas, developments in the DWDM-based backbone network are leading the way, followed by the DWDM-based LANs. The development on DWDM-based residential access networks seems to be lagging behind at the current time. The multiple channels of information (each having a different carrier wavelength) are transmitted simultaneously over a single fiber. The number of wavelength channels is above 20 in a WDM system, it is generally referred to as Dense WDM or DWDM.

4. Development of DWDM technology
Early WDM began in the late 1980s using the two widely spaced wavelengths in the 1310 nm and 1550 nm (or 850 nm and 1310 nm) regions, sometimes called wideband WDM The early 1990s saw a second generation of WDM, sometimes called narrowband WDM, in which two to eight channels were used. These channels were now spaced at an interval of about 400 GHz in the 1550-nm window. By the mid-1990s, dense WDM (DWDM) systems were emerging with 16 to 40 channels and spacing from 100 to 200 GHz. By the late 1990s DWDM systems had evolved to the point where they were capable of 64 to 160 parallel channels, densely packed at 50 or even 25 GHz intervals

5. VARIETIES of WDM
Early WDM systems transported two or four wavelengths that were widely spaced. WDM and the “follow-on” technologies of CWDM and DWDM have evolved well beyond this early limitation. (i) WDM:- Traditional, passive WDM systems are wide-spread with 2, 4, 8, 12, and 16 channel counts being the normal deployments. This technique usually has a distance limitation of less than 100 km.

6. (ii) CWDM:-
The CWDM grid is made up of 18 wavelengths defined within the range 1270 nm to 1610 nm spaced by 20 nm. (iii) DWDM:- Dense WDM common spacing may be 200, 100, 50, or 25 GHz with channel count reaching up to 128 or more channels at distances of several thousand kilometers with amplification and regeneration along such a route.

7. DWDM System function
It an optical technology used to increase Band width over existing fiber optic backbones. Dense wavelength division multiplexing systems allow many discrete transports channels by combining and transmitting In effect, one fiber is transformed into multiple virtual fibers. So, if you were to multiplex 32 STM-16 signals into one fiber, you would increase the carrying capacity of that fiber from 2.5 Gb/s to 80 Gb/s. Currently, because of DWDM, single fibers have been able to transmit data at speeds up to 400Gb/s. Dense WDM common spacing may be 200, 100, 50, or 25 GHz with channel count reaching up to 128 or more channels at distances of several thousand kilometers with amplification and regeneration along such a route.

8. Multiplexer or Demultiplexer
Combines/separates discrete wavelengths Multiplexer i s used to single o/p of multichannel Demultiplexer i s used to many o/p of single channel

9. Amplifier
Pre-amplifier boosts signal pulses at the receive side Post-amplifier boosts signal pulses at the transmit side (post amplifier) and on the receive side (preamplifier) In line amplifiers (ILA) are placed at different distances from the source to provide recovery of the signal before it is degraded by loss EDFA (Erbium Doped Fiber Amplifier) is the most popular amplifier

Stealth Technology Presentation Transcript:
1. WHAT IS STEALTH TECHNOLOGY????
Stealth technology also known as LO technology (low observable technology) The concept of stealth is to operate or hide without giving enemy forces any indications as to the presence of friendly forces. This concept was first explored through camouflage by blending into the background visual clutter. A modern "stealth" vehicle will generally have been designed from the outset to have reduced or controlled signature. Varying degrees of stealth can be achieved in a particular design by the prediction of likely threat capabilities.

2. STEALTH PRINCIPLES
Stealth technology (or LO for "low observe ability") is not a single technology but It is a combination of technologies as below Radar cross section reductions Acoustics Visibility Infrared Reducing radio frequency emissions

3. RADAR CROSS-SECTION REDUCTIONS
Almost since the invention of radar, various techniques have been tried to minimize detection. Some of the techniques used for this purpose are: 1. vehicle shape 2. non-metallic airframe 3. radar absorbing material

4. Vehicle shape
Aircraft shape makes a significant difference in detectability. Another important factor is the internal construction. Behind the skin of some aircraft are structures known as re-entrant triangles. Radar waves penetrating the skin of the aircraft get trapped in these structures, bouncing off the internal faces and losing energy Stealth design must bury the engines within the wing or fuselage. Planform alignment is also often used in stealth designs which returns a radar signal in a direction away from the radar emitter.

5. NON-METALLIC AIRFRAME
Dielectric composites are more transparent to radar, whereas electrically conductive materials such as metals and carbon fibers reflect electromagnetic energy incident on the material's surface. Composites may also contain ferrites to optimize the dielectric and magnetic properties of the material for its application.

6. RADAR ABSORBING MATERIAL
Radar-absorb Radar-absorbent material (RAM), often as paints, are used especially on the edges of metal surfaces. While the material and thickness of RAM coatings is classified, the material seeks to absorb radiated energy from a ground or air based radar station into the coating and convert it to heat rather than reflect it back.

7. ACOUSTICS
Acoustic stealth plays a primary role in submarine stealth as well as for ground vehicles. Submarines have extensive usage of rubber mountings to isolate and avoid mechanical noises that could reveal locations to underwater passive sonar arrays. Early stealth observation aircraft used slow-turning propellers to avoid being heard by enemy troops below. Stealth aircraft that stay subsonic can avoid being tracked by sonic boom

8. VISIBILITY
The simplest stealth technology is simply camouflage; the use of paint or other materials to color and break up the lines of the vehicle or person. Most stealth aircraft use matte paint and dark colors, and operate only at night. in daylight, against the clear background of the sky, dark tones are easier to detect than light ones or as a sort of active camouflage.

9. INFRA-RED
An exhaust plume contributes a significant infrared signature. One means of reducing the IR signature is to have a non-circular tail pipe order to minimize the exhaust cross-sectional volume and maximize the mixing of the hot exhaust with cool ambient air. Often, cool air is deliberately injected into the exhaust flow to boost this process. Sometimes, the jet exhaust is vented above the wing surface in order to shield it from observers below. To achieve infrared stealth, the exhaust gas is cooled to the temperatures where the brightest wavelengths it radiates on are absorbed by atmospheric carbon dioxide and water vapor, dramatically reducing the infrared visibility of the exhaust plume. Another way to reduce the exhaust temperature is to circulate coolant fluids such as fuel inside the exhaust pipe, where the fuel tanks serve as heat sinks cooled by the flow of air along the wings.

Secretariat LAN Presentation Transcript:
1. SEMINAR ON EXPANSION OF NETWORKS WITH SPECIAL REFERENCE TO SecLAN

2. INTRODUCTION:
A computer network is a group of computer and devices interconnected by computer channels. It allows sharing of resources and information among interconnected devices. Most networks use distributed processing in which a task is divided among multiple computers. In distributed processing, instead of one single large machine being responsible for all aspects of a process, separate computers handle a subset. A network must be able to meet a certain number of criteria. The most importatnt of these are performance, reliability and security.

3. What is LAN:
LAN or Local Area Network is a computer network covering a small physical area such as a home, an office or a small group of buildings. A LAN usually has high data transfer rates, small geographic place, and it does not requires leased telecommunication services. Other characteristics of LAN include full time connectivity to load services, generally lower in cost than a WAN and cabling in primary transmission medium.

4. LAN Design:
The design of a network affects most when it comes to the performance of the network. There are basically two design processes: General network design process Good network design rule

5. General network design process:
It consists of following three general elements: Enviornment given: it includes location of hosts, servers, terminals and other end nodes. Performance constraints: it consists of network reliability, traffic throughput and host/client computer speeds. Internetworking variables: it includes the network topoligy, line capacities and packet flow assignments.

6. Good network design:
It is also known as the 80-20 rule. In a properly designed network, 80 percent of the traffic on a given network segment is local. Not more than 20 percent of the network traffic should need to move across a backbone. Backbone congestion can indicate that traffic patterns are not meeting the 80-20 rule. In this case, network performance can be improved by: Moving resources Moving users Adding servers.

7. Virtual local area network
VLANs or Virtual LAN are used to simulate several logical Ethernet networks on the same physical infrastructure. VLANs are independent broadcast domain which don’t share any layer two communications. There are two main ways of defining VLANs: Per service: common services are grouped in a common VLAN, across many locations. Per location: VLAN scope is limited to a location, for example to a floor or a computer center.

8. OSI MODEL:
The open system interconnection model is a layered frame work for the design of network system that allow for communication across all types of computer systems. It consists of seven separate but related layers: Physical layer Data link layer Network layer Transport layer Session layer Presentation layer Application layer

9. Transmission media in local area network
The Transmission medium is material substance (solid, liquid or gas) which can propagate energy waves. There are three types of transmission medium used in LAN’s. These are twisted pair, coaxial cable and optic fiber. Twisted pair is mostly used in connections of star and hub networks. Coaxial cable is one of the most important kinds of transmission medium used in LAN’s. It is mainly used in bus network with baseband and broadband transmission. An optic cable is often used in backbone networks because its wide bandwidth is cost effective.

Specific Getting an “A” in Math and a “B” in Accounts is much more specific than just saying that you would like to get good grades this semester Measurable You’re more likely to keep up if you can see progress toward your goal. For example, getting an “A” on your midterm is measurable progress toward getting an “A” in the class.

3. Moderately
difficult A goal that is too hard or too easy will decrease your motivation and won’t show you what you’re really capable of accomplishing. Use what you’ve accomplished in the past as a guide Self-chosen You are much more likely to achieve a goal that you set for yourself than one that has been set for you

 4. Positive
Say what you do want to accomplish instead of what you don’t want to do. “I will attend all classes,” is much better than “I won’t skip any classes.” Realistic Winning a marathon after two weeks of training is an unrealistic goal. Use what you’ve accomplished in the past to set a reasonable goal for the future.

5. Flexible
If it looks like you can’t reach your original goal, be flexible and redraw your plan Associated with a deadline When do you plan on accomplishing this goal, in a month, day, or year?

6. Written down
It will serve as a better reminder to keep you motivated

7. Where goal setting can go wrong
When goal setting is disorganized For example, keep personal and academic goals separate When goals are unrealistic For example, becoming a company CEO immediately after graduation is an unrealistic goal Goals that are ‘beyond’ your control For example, winning the lottery is definitely beyond your control

8. When goals are vague For example, “becoming successful” or “becoming a better student” are not clear goals to work toward. When you set too many goals At any one time you should focus on achieving only three or four goals

 9. SMART Goals:
S – Specific
M – Measurable
A – Attainable or Achievable
R – Realistic
T – Time-bound

4. The Present
Yesterday is History Tomorrow’s a Mystery But Today is a Gift That’s Why They Call it The Present

 5. Time is a Non Renewable Resource
Once it is gone, it is gone. You will never see this moment again.

6. A Fordham University Study of first year students found the following: On weekdays students spent TWICE as much time on leisure activities as on studying. On weekends students spent SIX TIMES as much time on leisure activities as on studying.

7. Finding your LQ
For the next week, keep a close record each day of how much time you spend on leisure activities. Leisure activities are important to help you recharge, but too much can be detrimental.

8. Eighty Six Thousand Four Hundred
Picture this: Each day your bank deposits Rs. 86,400 in your checking account. There’s just one catch. You have to spend it all in one day. You can’t carry over any money to the next day.

9. What would you do? You’d spend it all, Right?

Assertiveness Presentation Transcript:
1. ASSERTIVENESS
“DON’T SAY YES WHEN YOU WANT TO SAY NO”
-Herbert Fensterhein

2. DOES IT HAPPEN TO YOU?
 Do you often find that others coerce you into thinking their way? Is it difficult for you to express your feelings openly and honestly? Do you sometimes lose control and become angry at others?

3. Do you yell at your group mates when they don’t pay any heed to your idea?
 “YES” is an expression of “LACK OF ASSERTION OR ASSERTIVENESS IN COMMUNICATION”

4. “I’m OK, you’re OK”: people are in the ‘get on with’ position “I’m OK, you’re not OK” : people are in the ‘get rid of’ position “I’m not OK, you’re OK”: people are in the ‘get away position’ “I’m not OK, you’re not OK” : people are in the ‘get nowhere’ position All four positions have bearing on individual thinking and subsequent verbal manifestations (communication)

5. AGGRESSION
Getting my own way anyway – cost to others, not my concern No interest or respect for the rights, wants or needs of others Usually destructive – physically or psychologically or both The basic message remains: “This is what I think – you’re stupid for believing differently. This is what I want – what you want is not important.”

6. AGGRESSION IMPORTANT PROCESS VARIABLES:
Invasive/angry staring-eye contact Loud strident voice, Invasion of spatial boundaries, Use of aggressive gestures Stiff or muscled up posture, Towering over others, etc

7. AGGRESSION AFTERMATH:
Aggression often breeds aggression- a vicious cycle Aggression can make us unpopular Aggression discourages helping hands in the future Short-term and myopic “feel-good” factor

8. PASSIVITY
Violating one’s own rights by failing to express honest feelings, thoughts and beliefs in a manner easily disregarded by others The basic message: “My feelings don’t matter – only yours do. My thoughts aren’t important – yours are the only ones worth listening to. I am nothing – you are superior.”

9. PASSIVITY
Behaving as other people’s rights matter more than our own Goal is to appease others and to avoid conflict at any cost Passive people don’t consider as if they have the right to: Have an opinion, Contribute, and Be valued

New Product Development Presentation Transcript:
1. WHAT IS PRODUCT PRODUCT LIFE CYCLE NEW PRODUCT DEVELOPMENT TYPES OF NEW PRODUCT CHALLENGES IN NEW PRODUCT DEVELOPMENT WHY NEW PRODUCT FAILS NEW PRODUCT DEVELOPMENT PROCESS

2. Before knowing what is New Product Development we must know what is product ? A product is anything that can be offered to a market to satisfy a need or want. Or We can say that product is anything which have the capability to satisfy the needs and wants of the customers or end users.

3. New Product Development (NPD); is “The term used to describe the complete process of bringing a new product or service to market.” “New product development refers to original products, product improvements, product modifications, and new brands developed from the firm’s own research and development” Or We can say that “The process of designing and launching the product into the market. Products that are either original, improved modified or new brands by means of research and development activities.”

4. Bozz, Hamilton & Allen identified six categories of New Products:- New to the world product New product lines Addition to the existing product lines Improvement & revisions of existing products. Repositioning Cost reduction

5. Several factors tend to hinder the new product development :- Social and government constraints. Shortage of ideas in certain areas. Fragmented market. Cost of developments Capital shortage. Faster required development time. Shorter product life cycle.

6. Poor organization system for handling New Product Ideas. Poor market planning. Poor forecasting and market research. High product development cost. Questionable pricing strategy. Bad timing of introduction of new product. Lack of advertisement. Poor product decision. Over optimism about market plans.

7. The following steps which are followed in New product development process are as follows:- Idea generation Idea screening Concept development and testing Marketing strategy development Business analysis Product development Marketing strategy Test marketing Commercialization

8. It is necessary for growth of enterprises. It ensures the sales and profit maximization of the firm. All products decline with time (life cycle)‏ The market is dynamic. Technical innovation is permanent etc…….

9. So to conclude we can say that new product development is necessary to establish an effective organization for managing the development process. Marketing should participate with other departments in every stage of new product d development.

Fiber Optics Presentation Transcript:
1. HISTORY
It began about 40 years ago in the R&D labs (Corning, Bell Labs, ITT UK, etc.) first installed commercially in Dorset, England by STC and Chicago, IL, USA in 1976 by AT&T. By the early 1980s, fiber telecommunications networks connected the major cities . Modern fiber-optic communication systems generally include an optical transmitter to convert an electrical signal into an optical signal to send into the optical fiber. The information transmitted is typically digital information.

2. Why Optical Fibers ?
As mans need for communication increased, the amount of bandwidth required increased exponentially. Initially we used smoke signals, then horse riders for communicating. But these ways were way to slow and had very little bandwidth or data caring capacity. Optical Fiber,~ the diameter of human hair, can carry 5,00,000 circuits of voice and data. This capacity is increasing day by day as supporting electronics is developing.

3. The light source (LAZER) at the transmitting (Tx) end is modulated by the electrical signal and this modulated light energy is fed into the Optical Fiber. At the receiving end (Rx) this light energy is made incident on photo-sensors which convert this light signal back to electrical signal.

4. Telecommunications
Internet Access Cable and Satellite Television Decorative Light Source

5. Components
Cladding-cover with a protective or insulating layer of other material

6. Characteristics
Glass Core Glass Cladding Ultra Pure Ultra Transparent Glass Made Of Silicon Dioxide Low Attenuation Popular among industries

7. VARIOUS TYPES OF OPTICAL FIBER CABLES
OPGW Cable ADSS type OF Cable Self-Support AERIAL figure 8 type OF Cable LASHED type OF Cable UNDERGROUND / BURRIED type OF Cables DUCT Type OF Cable

8. Fiber Optic Connectors
Since fiber optic technology was introduced in the late 70s, numerous connector styles have been developed - probably over 100 designs. Each new design was meant to offer better performance

9. Types Of Fiber Optic Connectors
The ST/SC connectors about 0.1 inch - so they can be mixed and matched to each other Volition is a simple, inexpensive duplex connector It aligns fibers in a V-groove like a splice.
