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 Fiber-
Complete capable modules (see references in
meters on the mainframes.
Using one unit at each end of the fiber under test and without any connection/disconnec-
tion, 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 automatically:
• 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 automatically in order
to identify the faulty event.
