. Fiber optic
Communication system has emerged as most important communication system.
Compared to traditional system because of following requirements :
1. In long haul
transmission system there is need of low loss transmission medium.
2. There is need of
compact and least weight transmitters and receivers.
3. There is need of
increased span of transmission.
4. There is need of
increased bit rate-distance product.
. A fiber optic
communication system fulfills these requirements, hence most widely accepted.
