A High Power and Low Noise Transmitter for AM-VSB Transmission Using Erbium-doped Fiber Post Amplifier

Abstract

Erbium doped fiber amplifiers(EDFAs) with high output power and no distortion degradation are very useful for the amplitude-modulated vestigial-sideband(AM-VSB) transmission systems which require a relatively high received power for a preferred carrier to noise ratio(CNR) and a low distortion[1][2], A field trial was conducted and feasibility of multidistribution for trunk lines was confirmed[3].
