Install Fibre-Optic Cables
This section discusses the hardware and methods required to connect and
route fibre-optic cables.
The Expansion Port Network (EPN) c a binet is normally p ositioned next to the
Processor Port Network (PPN) c abinet(s), but may also be installed in a different
room or a different building. Fibre-optic cables connect the cabinets together.
Fibre-Optic Cable Operation
Fibre-optic cables carry signals between the c a...

In the example Running List in Figure 4-12, connect a cable labeled 104266465
(20 feet long) from Cabinet 1, Carrier C, Slot 2, to Cabinet 2, Carrier B, Slot 2.
NOTE:
The following tasks refer to the Running List and offer typical installation
instructions. If any conflict b etween s pecific details in the Running List and
the instructions given in the following procedures arise, cable...

Rule 3
Route fibre-optic cables away from groups of other c a bles where they may b e
stretched by the weight of metal cable bundles, as fi bre-optic cables are q uite
flexible.
Rule 4
Avoid bending fibre-optic cables to a radius smaller than 1-1/2 inches (4 cm), to
prevent mechanical stress on the cables, as they are rather delicate. Plan your
use of c a ble ties to avoid crimping the cable or creating a fixed stress point
where, at a later...
