Do NOT stare directly into the beam as this can damage your eyesight.
When handling the fiber optic cables, be sure to implement the following
points:
Excessive bending of the Fiber Optic Cable can cause distortion and signal
losses
Ensure the minimum bending radius recommended by the Fiber Optic Cable
supplier
Maximum Fiber Optic Cable length for multimode fiber is 2 km
Maximum Fiber Optic Cable length for monomode fiber is 22 km
Incoming optic cabling from the network infrastructure can originate from the
top of the rack or from another shelf within the rack. Preserve the minimum-
bending ratio indicated by the cable manufacturer.
To assure full high-availability capabilities, the configuration of the interface
to the IP backbone must include certain redundant features from which two
separate fiber optic cables are incoming to the Media Gateway 3500 Media
Gateway. For more information on, refer to the section below.
