When routing the fiber-optic cables to the Fiber Remote Multi-IPE Interface
units, take the following precautions:
•
•
•
•
Handle fibers with extreme care. Observe a minimum bending radius at all
times. Optical connections to the optical units should be finger-tightened
only.
The link fiber labeled XMIT A at the remote site must be labeled RCV A at
the local site, and the link fiber labeled RCV A at the remote site must be
labeled XMIT A at the local site. For a redundant link, label XMIT B at the
remote site as RCV B at the local site, and RCV B at the remote site as
XMIT B at the local site as shown in

.
Do not bend the fiber-optic cable or individual fibers beyond the
minimum bending radius specified by the cable manufacturer.
Protect the exposed parts of the cable and fibers with plastic conduit.
Terminate each selected fiber with an ST optical connector (a
fiber-optic cable may contain more fibers than required by the single
or redundant link design). At the fiber management frame, the type
of optical connectors used depends on the available frame optical
connectors.
Label optical fibers with XMIT A (transmit) and RCV A (receive)
designator behind the ST optical connector for the primary link and
XMIT B and RCV B for the redundant link to identify the function of
each fiber in the link.
