PowerPoint Presentation On Fiber Optics

Fiber Optics PPT


Fiber Optics Presentation Transcript:
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

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.
