Abstract :
Demonstrates a two-channel FDMA-FSK star network using frequency-tunable two-electrode DFB lasers. Channels are demultiplexed by a tunable fibre Fabry-Perot filter, which also converts the FSK signal to ASK format for noncoherent detection. Bit error rates of 10-13 have been measured at 600 Mbit/s transmission rate for (223-1) word lengths. High bit rate and frequency tunability have thus been combined for use in an FDMA.
