Abstract

The performance of a hybrid AM-VSB/BPSK optical fiber transmission system utilizing a 1.55 micrometer distributed feedback (DFB) laser and an Er doped optical amplifier is presented. A BPSK modulated 2 MHz pseudo-random digital channel is substituted for one of the AM channels in a 60 channel CATV system and optically transmitted using a directly modulated 1.55 micrometer DFB laser. The intermodulation distortion effects with and without optical amplification were studied. No degradation of the AM channels is observed unless the modulation depth of the BPSK channel is increased to the point where laser clipping effects become significant.
