摘要：

A total of 16 DFB lasers with 10 GHz frequency spacing were combined to transport 160-channel FM television signals to 16 locations; each link distance was 9km with an average power margin of 7·5 dB. The 16 optical carriers were simultaneously modulated by a composite of 10 FM-video signals. A high-finesse optical Fabry-Perot etalon with a half-intensity width of about 1·5 GHz and a free spectral range of 4 nm was used, both as an optical channel filter and as a frequency discriminator. An erbium doped fibre amplifier was used to provide a net gain of 9·2 dB. © 1990, The Institution of Electrical Engineers. All rights reserved.
