General introduction
Principle
FiberComplete is used to perform automatically and through a single
connection port, the following tests:
– Bidirectional insertion loss (IL)
– Bidirectional optical return loss (ORL) using the continuous wave
method (OCWR)
– Distance/length measurements
– Unidirectional / Bidirectional OTDR or fault analysis
To carry out the measurements, 2x T-BERD/MTS are needed, both
equipped with FiberComplete capable modules (see references in
Chapter 11 ) and broadband power meters on the mainframes.
Using one unit at each end of the fiber under test and without any
connection/disconnection, IL/ORL and distance measurements are
performed and results exchanged via the fiber under test (FUT).
If the OTDR is selected, an OTDR measurement is launched automati-
cally:
–
Unidirectional mode
: the OTDR acquisition is performed from the
primary unit where the test has be initiated. Traces are saved locally
–
Bidirectional mode
: the OTDR acquisition is initiated successively
from each unit. The traces are saved locally.
A failed value of IL or ORL may trigger the Fault Finder function automat-
ically in order to identify the faulty event.
