Connecting an FP cable
Connect an FP cable to enable an installed or replaced FP to transmit and
receive traffic signals, and connect all cables in sequence for an initial
installation to minimize cable congestion on the front of the Passport 15000
or 20000.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You must ensure that all FP cables are routed and labelled as described
in “Routing FP cables” (page 827).
• You must install all attenuators that are required by an optical FP, as
described in “Determining if you need to use inline attenuators with
optical FPs” (page 345).
• For FPs requiring small-form pluggable (SFP) optical transceiver
modules on the faceplate sockets (ports), you must ensure that the part is
installed according to“Installing an SFP optical module” (page 588).
CAUTION
Risk of service loss
Before connecting any cables to an FP, ensure it is
properly seated. Seating a cabled FP can cause a traffic
loss on the other FPs in the sparing configuration.
CAUTION
Risk of damage to the fiber transceivers on the FPs
When engaging or disengaging a fiber optical cable
connector to the connector on the FP faceplate (the
transceiver), you can damage the nose shield on the
connector or the optic transceiver by improper coupling.
This especially applies to MT-RJ connectors.
Refer to the table “Actions to engage types of FP
connectors” (page 324)
