Fiber Optic Interconnect Cabling
Signals between the cabinets are carried by fiber optic cables. Lightwave
transceivers provide the required fiber optic interface.
The fiber optic cables from the DEFINITY System route to a Lightguide
Interconnect Unit (LIU) or fiber optic shelf. Refer to Appendix A, ‘‘
Connecting
Fiber Optic Cables’’. Refer to this information for fiber optic equipment comcode
numbers, connecting to LIUs or shelves, and routing through lightguide
equipment.
Use multi-mode fiber transceivers and multi-mode fiber optic cables between
cabinets unless single-mode fiber is required (distance restrictions). Use metallic
cables between carriers.
