Design and Implementation DWDM Toward Terabit for Long-Haul Transmission System

In this paper we present design and implementation of high-speed transmission system toward Terabit/sec based on Denise Wavelength Division Duplexing (DWDM) system. The presenting system consider new solution to carrying rise data rate for long-haul optical transmission system. The system examined for various number of channel (4, 8, 16, and 25). The obtained results show that the propose system immunity for the non-linear impairments. As well as, the performance analysis of different number of optical channels with different data formatting technique such as Return-to-Zero (RZ) and Non-Return-to-Zero (NRZ) is presented.
