Implementation of CATV Network Using Different Dispersion Compensating Techniques

The main objective of the paper is to implementation of 16-QAM CATV (Community Antenna TV) system. To achieve this task, various dispersion compensation techniques that are more suitable for CATV system in the near future, are determine. It is necessary to use dispersion compensation devices .Dispersion compensation techniques have many advantages as a smooth dispersion profile (i.e. no dispersion ripples or group delay ripples), are tunable, and potentially provide a high channel-to-channel variation in the dispersion. It describes the affect of different dispersion compensation techniques on the eye opening, eye closure, bit-error rate (BER), Q-factor without the use of an optical amplifier, with the use of optical amplifier.This paper uses OPTSIM V3.6 and MATLAB software to simulate various dispersion compensation techniques. To extend the transmission distance is the goal of the fiber optical CATV transport systems.
