Abstract :
The design and performance are described of a field-deployable fiber-optic video distribution system using bi-phase-shift-keyed (BPSK) microwave subcarrier multiplexing techniques to provide each subscriber with twenty 107-Mb/s digitized video signals and one 2.04-Mb/s voice/data signal, giving a total transport capacity of 2.144 Gb/s. The microwave subcarrier frequency covers the range from 1.9 GHz to 5.9 GHz. The 21 microwave subcarriers are multiplexed together to intensity modulate a high-speed 1.3- mu m single-mode laser dedicated to each subscriber. Each subscriber station is equipped with a high-frequency p-i-n diode detector followed by microwave receivers. A bit-error rate of 10/sup -9/ is achieved at a laser modulation depth of 5% and a received optical power of -12 dBm.<>
