Abstract

A multichannel fiber optic communication network incorporates multichannel fiber optical amplifiers having different functions but designed to use substantially identical gain flattening filters. This is achieved by designing the amplifiers to have total insertion losses such that their respective internal gains (internal gain=net gain+total insertion loss) are substantially the same, most preferably within 1 dB.
