WARNING:
Unterminated optical connectors may emit invisible laser radiation. Aviod
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.
NOTE:
This test is used locally at the DDM-2000 FiberReach shelf to verify the
integrity of the OC-1, OC-3, or OC-12 fiber lines between two DDM-2000
FiberReach shelves or between a DDM-2000 FiberReach shelf and a
DDM-2000 OC-3 or OC-12 shelf and may be performed with the
DDM-2000 in service or out of service.
NOTE:
It is assumed that each DDM-2000 has passed the local (looped)
transmission tests and a CIT is available. If these tests have not been
completed, refer to the appropriate procedure and perform the tests.
NOTE:
This test must be performed locally at each shelf location associated with
the optical span(s) being tested. See Figure .
