Abstract:
1. A transition device for an optical fiber connection system, the transition device adapted to interconnect a trunk cable with a plurality of transceivers, the transition device comprising: a first set of at least four optical fibers, each of the optical fibers having a trunk end and a transceiver end; a single trunk end terminal having a plurality of trunk ports, each port connected with a respective one of the set of optical fibers at its trunk end, wherein a first axis of symmetry divides the ports; and a plurality of transceiver end terminals, each of the transceiver end terminals having even numbers of transceiver ports, each of the transceiver ports receiving a respective one of the set of optical fibers at their transceiver ends; wherein the fibers received by each transceiver end terminal meet either of the following two conditions: (a) a first fiber originates from a first port in the trunk end terminal, and a second fiber originates from a second port in the trunk end terminal that is positioned at the mirror image location of the first port about the first axis of symmetry; or (b) each fiber is received in a first transceiver end terminal that has a corresponding second transceiver end terminal with the same number and arrangement of transceiver ports, and each fiber received in the first transceiver end terminal originates from a port in the trunk end terminal that has a mirror image port about the first axis of symmetry from which a fiber that is received in the second transceiver end terminal originates; wherein at least one of the transceiver end terminals has a different number of ports than at least one of the other transceiver end terminals.
