Connecting and Handling Fiber Optic Cables
Optical Cross-Connect Hardware
Optical cross-connects consist of Lightguide Interconnect Units (LIUs) with lightguide troughs in between them. Typical Optical Lightguide Interconnect Unit shows a typical LIU. One LIU terminates the incoming cables and the other terminates the outgoing cables. A fiber optic patch cord or jumper is used to connect the circuits. Circuits can be rerouted the same as on 110-type connecting blocks, by moving the patch cord from one point on the Main Distribution Frame (MDF) to another.
Optical interconnects consist of Lightguide Interconnect Units (LIUs) without a trough between them. Typical Optical Interconnect Field shows a typical Interconnect field. Incoming and outgoing multi-mode and single-mode cables are connected directly to each other. This arrangement makes circuit changes more difficult, but reduces optical losses.
