  • Fiber quadrupler device method for providing full duplex communications to a synchronous optical network over a single optical fiber
    Patent number: 6597479
    Abstract: A fiber quadrupler device and method multiplexes the four optical fibers in a synchronous optical network (SONET) ring into a single linking fiber for full duplex optical transmission. The fiber quadrupler device optically couples two of the SONET fibers to a transmit converter for communications of downstream data from the SONET ring to a network element linked to the quadrupler by a single linking fiber. Two other SONET ring fibers are optically coupled to a receive converter for communications of upstream data from the network element over the single linking fiber to the SONET. An optical transceiver processes and directs the downstream and upstream signals to the receive and transmit converters. Either subcarrier modulation (SCM) or wavelength division multiplexing (WDM) is used in the receive and transmit converters.
