摘要
A method for analyzing the transmission capacity of DWDM system in C band has been proposed according to the data rate of a channel and the fiber link configuration. Aiming at three typical systems at 112Gbps, 480Gbps, and 1.2Tbps channel speed respectively and the link is composed by several spans with 80km SSMF, the result of the analysis indicates that 480Gbps system can afford the biggest capacity in C band when distance of transmission without electric regenerator is in range of 300km to 1000km, while the distance is longer than 2200km, 1.2Tbps system becomes the one with the biggest capacity.
