To install the fiber-optic link to the Fiber Remote IPE, the link fibers
must be terminated with FC/PC optical connectors at the local site. At
the Fiber Remote IPE, the link fibers are also terminated with FC/PC
optical connectors for the floor-standing modular system. For the
wall-mounted cabinet system, however, the link fibers are terminated
into a fiber-management frame and continue from the fiber management
frame to the Electro-optical packlet FC/PC optical connectors on the Fiber
Peripheral Controller faceplate.
When routing the cables to the local column, the floor-standing Fiber
Remote IPE column, or wall-mounted Fiber Remote IPE cabinet, take the
following precautions:
•
Do not bend the fiber-optic cable or individual fibers beyond the
minimum bending radius of 1.4 inches (3.5 centimeters).
•
Protect the exposed parts of the cable and fibers with plastic conduit.
•
Terminate each selected fiber with an FC/PC 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.
Mark each fiber with Tx (transmitting) or Rx (receiving) designator behind
the FC/PC optical connector to identify its function in the link.
WARNING
When handling optical fibers, follow the recommended safety
procedures at all times.
Before handling optical fibers, take necessary training and
become certified in working with fiber-optic cables.
If possible, shut off power to all external transmission equipment so light
beams will not be present at the exposed ends of the fiber cables. Keep all
connectors capped while the cables are disconnected.
Handle fibers with extreme care. Observe a minimum bending radius of
1.4 inches (3.5 cm) at all times. Optical connections to the optical units
should be finger-tightened only.
