【Abstract】 The optical code division multiplex access communication system, which encodes the spectral amplitude of incoherent optical sources , is proposed. Compared with the prevenient system encoding the information in the time domain by ultra short pluses, the OCDMA system works with low cost incoherent sourcs and encodes orthogonal signaling. The system not only utilizes the bandwith of fiber well, but also reduces the cost of system. The effect of spectral shape of light source on system performance is also studied.更多还原
