QUICK CARD
► Use the VIAVI P5000i or FiberChek Probe
microscope to inspect both sides of every
connection being used (OCC Port, bulkhead
connectors, patch cables, etc.)
► Focus fiber on the screen. If dirty, clean the
end-face.
► If it appears clean, run inspection test.
► If it fails, clean the fiber and re-run inspection
test. Repeat until it passes.

DWDM Optical Channel Checker
This quick card describes how to connect to a fiber under test, configure DWDM Optical
Channel Checker (OCC) test setups, run tests, and analyze results with a T-BERD/MTS-
2000 equipped with an OCC-4056C module.
Note: The OCC module is used to monitor wavelengths on a live network. Care
should be exercised when unplugging fibers from the network as the fibers
may be carrying traffic.
► T-BERD/MTS-2000 equipped with the
following:
► Fiber Optics Software Release V21.0 or
greater
► OCC-4056C DWDM OCC Module
► Fiber optic cleaning and inspection tools
► Fiber optic patch cable (Launch Cable)
► Optical Coupler to connect patch cable to
Fiber Under Test

CONNECT TO FIBER UNDER TEST (FUT)
All fibers and connectors should be cleaned and inspected prior to connection, as described on page 1.
The Nano OSA is typically connected to the FUT via a Monitor Port or splitter/tap to not disrupt service.
The Nano OSA can also be directly connected to the common port or common fiber via a coupler during
turn up or maintenance:
1. Inspect the OCC port on top of the test set.
2. If connecting to the Common Cable, connect the Common
Cable to an optical coupler with the same connector type and
inspect the fiber end face in the coupler.
3. If connecting to the Monitor Port or Common Port on the Mux,
inspect the Mux Port.
4. Inspect the fiber end face of the Patch Cable and connect the
cable to the OCC port.
5. Inspect the other fiber end face of the Patch Cable and Connect
the Launch Cable to the coupler or Mux port.
