We report the results obtained with a densely spaced FDM coherent optical fiber star network utilizing monolithic frequency-tunable lasers to generate optical signals FSK at 200 Mb/s, which provides an optical receiver sensitivity of 74 photons/bit at a BER of 10-9 and random access channel selection by computer control of the receiver LO laser frequency. The results indicate that this system has the potential to provide a throughput of 2000 Gb/s.
