Abstract

This paper investigates the performances of 16×100Gbit/s return-to-zero differential quadrature phase shift keying (RZDQPSK) coded modulation signals in dense wavelength division multiplexing (DWDM) system and compares three different dispersion compensation fiber (DCF) methods. The performance has been evaluated by using Q value as the major parameter along with the variation of the input power for different channels with different dispersion compensation schemes. It is observed that symmetrical compensation of DCF is more excellent than pre-compensation and post-compensation methods. Corresponding to symmetrical compensation of DCF method, the maximum values of Q factor are 11.7026, 10.5128 and10.5138 for channel NO.1, channel NO.8, and channel NO.16, respectively. Meanwhile, the eye diagram shape of symmetrical compensation method is superior to the others.
