摘要

高输出功率且无失真退化的掺铒光纤放大器(edfa)在调幅残余边带(AM-VSB)传输系统中非常有用，该系统需要较高的接收功率以获得首选载波噪声比(CNR)和低失真[1][2]，进行了现场试验并证实了干线多重分布的可行性[3]。

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

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].
