| Summary: | In this article, a new 4-channel dense wavelength division multiplexing
(DWDM) optical transmission system model is proposed with
dispersion compensation techniques. Dispersion compensation
mechanism limits the pulse broadening effects of transmitted light in
optical communication systems. To overcome dispersion problem; Pre,
Post and Symmetrical dispersion compensation scheme are modeled,
analyzed and compared for investigate the performance of DWDM
system. The proposed model is designed for 8Gbps using non-returnto-zero (NRZ), return-to-zero (RZ) and Gaussian modulation format
with erbium doped fiber amplifier (EDFA) over a length of 150km
single mode fiber (SMF) and 30km dispersion compensation fiber
(DCF). The performance of designed model is compared in terms of bit
error rate (BER) & Q-Factor and it is observed that, the symmetrical
dispersion compensation scheme with RZ pulse generator modulation
gives best performance for long-haul transmission system.
