Abstract
A multi-star fiber optic network includes a series of two or more passive transmission stars disposed in different local areas, each star serving terminal devices in its local area. A pair of repeaters between each successive star of the series receive optical signals on one channel and transmit the information on at least one different channel, thereby avoiding repeated reflections between successive stars. Wavelength multiplexing, frequency modulation, and amplitude modulation techniques may be employed to provide the different channels, one of which may be a baseband channel. Modified amplitude techniques may be employed to provide directional enable or inhibit signals on different channels.
