2.3.2 Optical Fiber Connection
Most cable manufacturers identify individual fibers in the
fiber cable. Select an appropriate terminated fiber. Each
unit’s optical ports in the system are specified for use with
Multimode (62.5/125 micron) fiber, or Singlemode (9/125
micron) fiber. Follow the ensuing instructions on installing
and connecting the fiber optic links:
1. Ensure the power is off before proceeding with the fiber
optic cable installation.
2. Prior to connecting the fiber optic cables, remove and
save the dust caps from the optical port of both the
4900 units. Clean the fiber optic connector and use a
lint-free cloth dampened with alcohol to thoroughly wipe
the side and end of the ferrule.
3. Cross-connect the fibers from one unit to the other,
connecting the near end 4900 unit’s optical TX port to
the far end 4900 unit’s optical RX port, as illustrated in
Figure 2-1. Observe the type of connector you have
and connect the optical connector.
