Connecting and Handling Fiber Optic
Cables
Signals between the cabinets composing the system are carried by fiber optic cables. To accomplish this,
the electronic signals at the connectors on the back of a cabinet must be converted into optical signals,
and optical signals from another cabinet must be converted back into electronic signals. Opto-electronic
devices (lightwave transceivers) provide this interface.

Detailed Information
See Optical Cross-Connect Hardware on page 763 for hardware details.
See Cleaning Fiber Optic Cables on page 768 for cleaning instructions.
Optical Cross-Connect Hardware
Optical cross-connects consist of Lightguide Interconnect Units (LIUs) with lightguide troughs in
between them.
Figure 300, Typical Optical Lightguide Interconnect Unit, on page 764 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
