Effects of EDFA on the Capacity of Optical Communication System
The information capacities of optical communication system with erbium-doped fiber amplifier (EDFA) are studied. Ignoring fiber nonlinearities and dispersion, the expression of system information capacities with EDFA is derived using information entropy theory. It is shown that EDFA introduces information loss, and 4-11 (bit/s/Hz) of information capacities is obtained.
