Fiber - Optical Communications - Links (P2P) The point-to-point connection is a fiber-optic link (or fiber channel) which is a part of an optical fiber communications system. It comprises of :  Data Transmitter  Transmission Fiber  Receiver

Transmitter

The transmitter is a device that converts the electronic input signal into a modulated light beam, in this case. This could be encoded using • Optical power • Optical phase • Polarization

If high data rates are required, the transmitter needs to meet a number of requirements particularly • a high extinction ratio • a low timing jitter • low intensity noise • a precisely controlled clock rate • Stable and reliable operation

Optical Fiber

The transmission fiber chosen in general is single-mode fiber for handling both medium or long-distance transmission and a multimode fiber for short distances, preferably. But the usage of Multimode Fiber could possibly limit the transmission distance or bit rate intermodal dispersion.

Receiver

A photodetector, normally a photodiode along with suitable high-speed electronics is utilized to amplify the weak signal and extract the analog/digital data. The circuitry for electronic dispersion compensation can be added in order to ensure higher data rate transmission.
