Abstract:
1. A network for providing redundant, full duplex, communications, said network comprising: a first network end device; a second network end device; a plurality of complimentary, bi-directional, transceiver pairs, a first said transceiver pair communicatively coupled respectively to said first and said second network end devices to form a first separate network portion, a second said transceiver pair also communicatively coupled respectively to said first and said second network end devices to form a second separate network portion, said transceiver pairs configured for single mode operation, and allocated to said network end devices by transmission and reception wavelength to assure interoperability of redundant systems within said network; and a plurality of multimode optical fibers optically coupled to said transceiver pairs to provide the communicative coupling therebetween, each said multimode optical fiber configured for full duplex communication, each said multimode optical fiber forming at least a portion of a separate network portion between respective said transceiver pairs.
