Line coding method for fiber optic communication
Note: In order to ensure enough transitions in the data most communication systems, using fibre optics, use nonreturn–to–zero inverted (NRZI) coding. In NRZI coding, a 0 is represented as a change of state on the line and a 1 as the absence of a change of state, or vice–versa. ◮ Connections between nearby logic gates have bandwidth greater than switching speed, so no line coding is needed. The goals of line coding are to transmit binary data like voice, video or financial. Abstract- In this paper, different types of line coding techniques used for digital optical fiber communication have been discussed. Fiber-optic communication is a way of transmitting information from one place to another by sending pulses of light through an optical fiber (usually made of glass or plastic), and has formed an integral part of the core network across many countries.
