Abstract : A low-cost multichannel optical network testbed is described based on optical subcarrier multiplexing with low-coherence self-pulsating laser diodes and multimode fiber links. The testbed uses commercially available 79Onm self-pulsating laser diodes (SP-LDs), multimode fiber, and GaAs OEIC single-chip receivers. The choice of these components virtually eliminates the laser beat-noise and modal noise and thereby makes the implementation practical. Potential applications of the network include workstation clusters, multiprocessor interconnection, and switch emulation.
