Performance analysis of 4 channel CWDM using EDFA based on extinction ratio and fiber length
... In this paper we enlightened the use of EDFA in order to compensate dispersion loss in optical fibers. From the above simulations we got some optimized value for 40,50,60,70,80 Km long distance communication. Optimized ...
