Abstract

This paper successfully demonstrate point-to-point (P2P) 2.5 TB/s DWDM system in downstream for 100 wavelengths having 0.4 nm (50 GHz) channel spacing by using post-dispersion compensation scheme. Each channel is transmitting 25 GB/s data rate in down link. A 20 km dispersion compensating fiber (DCF) followed by 80 km standard single mode fiber (SSMF) which passes 20 times through fiber span for compensating the chromatic dispersion. The maximum reach of designed system is (100×20) 2,000 km. In this paper we also performed the comparison of different modulation formats such as NRZ, RZ and CRZ. It has been observed that CRZ modulation format can achieve BER as better as e−9 for each channel, which gives best performance. The performance of designed system is compared in terms of Q-factor, eye diagrams and BER.

Keywords: dense wavelength division multiplexing (DWDM); non-return to zero (NRZ); return to zero (RZ); chirped return to zero (CRZ); single mode fiber (SMF); dispersion compensation fiber (DCF); bit error rate (BER); quality factor (Q-Factor).
