    摘要: A ladder architecture (10) comprises an input optical fiber bus (12) and an output optical fiber bus (14). A plurality of input optical couplers (16A, 16B, etc.) couple light between the input bus (12) and a plurality of branching fibers (18A, 18B, etc.). A plurality of output couplers (20A, 20B, etc.) couple light from the branching fibers (18A, 18B, etc.) to the output bus (14). The input bus (12) and the branch fibers (18A, 18B, etc.) may be single mode optical fibers while the output bus (14) is a multimode optical fiber. The input couplers (16A, 16B, etc.) may be symmetrical, single mode devices, and the output couplers (20A, 20B, etc.) may be asymmetrical and single mode to multimode devices. The input bus (12) may also be a multimode fiber, and the input couplers (16A, 16B, etc.) may also be multimode to single mode devices. The asymmetrical coupling reduces the amount of signal lost at fiber ends.

    摘要: A lattice (10)includes a transmit bus (14) formed of a single mode optical fiber and a return bus (16) formed of a multimode optical fiber. An optical transmitter (12) applies input signals to the transmit bus (14), and an optical receiver (20) receives the signals guided by the return bus (16). The return fiber bus (16) is looped around the couplers (18A, 18B, etc.) so that the signal output from each segment of the lattice (10) passes through all the preceding segment sbefore reaching the receiver (20). The optical couplers (18A, 18B, etc.) have asymmetric coupling efficiencies so that recirculating light is attenuated.
