1.
WARNING:
Unterminated optical connectors may emit invisible laser radiation. Avoid
direct exposure to the beam. Do not view beam with optical instruments.
Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
!
CAUTION:
When handling optical pigtails or jumpers, take care to keep bending
radius as large as possible.
NOTE:
This procedure is used to connect OC-12, OC-3, and OC-1 optical fiber
spans. For each span, determine the loss of each optical fiber and install
the proper LBO. Then connect the fibers to the associated IN and OUT
connectors of each OLIU at the end of the span.
NOTE:
When installing LBOs, the rule for single-mode optical fibers is for the
LBO to be installed on the OUT transmit connector of the OLIU. For
multimode optical fibers, install the LBO on the IN receive connector of
the OLIU.
NOTE:
It is assumed that the optical jumpers used to connect the DDM-2000
OC-3 Multiplexer to an optical interconnection point are equipped with
®
ST , FCPC, or SC lightguide cable connectors.
Dress optical cables at bottom front of the shelf.
2. Route the optical jumpers up through the slotted hole(s) at the bottom left-front
corner of the shelf and up to the OLIUs. See Tables A and B.
