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.

Abstract: A glass composition well suited for use in optical amplification consists of an erbium-doped borate glass composition comprising at least 30 mole percent of B2O3, not over 30 mole percent of SiO2, preferably not over 5 mole percent of La2O3, a ratio of B2O3 to (SIGMAX2O+SIGMAYO) that is at least 3.5, preferably 4.5, where X2O represents monovalent metal oxides(s) and YO represents divalent metal oxides, the glass providing a wide useful bandwidth (50 nm and greater) for optical amplification around the 1545 nm region.
