Abstract :
The transmission bandwidth of SCM systems is not determined by the availability of electronics, but by the modulation characters of high speed semiconductor lasers. The authors analyze the limitations on SCM systems imposed by laser modulation depth and by second order laser intermodulation products. The performance potential of wideband SCM systems is demonstrated with three systems experiments: a 120 channel FM video transmission using the 2.8-7.6 GHz band; the combination of 60 FM channels and a 100 Mb/s baseband digital signal; and a 20 channel FSK system transmitting 100 Mb/s channel in the 2-6 GHz band
