ABSTRACT:
A passive optical network is provided that spectrally slices optical signals transmitted in both upstream and downstream directions utilizing wavelength division multiplexing routing. The passive optical network preferably includes a broadband optical signal source at both ends to provide signals that are spectrally sliced according to optical frequency. The downstream information may be transmitted in a conventional data format. The upstream transmissions may be segregated by subcarrier multiplexing, time scheduling or wavelength division multiplexing. At the subscriber end of the network there is an optical network unit which includes a device coupling the downstream fiber to the upstream fiber. Such coupling allows the passive optical network to perform enhanced diagnostic tests.
