Selective broadcast interconnection: a novel scheme for fiber-optic local-area networks

Opt Lett. 1985 Dec 1;10(12):629-31. doi: 10.1364/ol.10.000629.


We introduce a passive, unswitched scheme for directly interconnecting N stations, each of which has C transmitters and receivers. Implementations using fiber optics with spatial multiplexing and optionally wavelength multiplexing are discussed. This scheme utilizes the same resources as standard topologies with C parallel buses but outperforms them in two respects: (1) the aggregate throughput is proportional to C(2) rather than to C and (2) the power of each transmitter need reach only N/C, instead of N, receivers.
