2.2 Fiber Inspection Guidelines
• All fiber end-faces must be
clean and pass an inspection
test prior to connection.
• Use the VIAVI P5000i or
FiberChek Probe microscope
to inspect both sides of
every connection being used
(SFP Port, bulkhead
connectors, patch cables,
etc.)
2.3 Fiber Testing
All fibers and connectors should PASS the fiber inspection guidelines prior to connection.
The OTDR may be connected to the fiber under test as follows:

Launch Cable is directly
connected to the OVP.
- Set RRU Jumper to Yes if there
is a Junction Box/OVP at the top
of the tower between the Trunk
Cable and RRU
- Set RRU Jumper to No if there is
no Junction Box or no RRU
Jumper.
Configure Link Description settings
as follows:
- Set Base Station ID to the Base
Station or BBU Identifier.
