Table 3 Quality of connection
Possible causes of a bad result:
- There are several connectors close to the external connector of the T-BERD/
MTS.
Bad - One of the connectors is dirty or badly connected. Replace the launch cable,
make the connection again properly or clean the connector of the OTDR or of
the jumper.
- No fiber is connected.
If the state of the connection is bad, it is still possible to carry out a measurement, but
the results will not be very reliable.
NOTE
If the connection is bad, check and clean the connector / jumpers (see
"Cleaning the universal connector" on page
Battery saver
When running on battery, if no acquisition has been performed for two minutes, the
power supply of the module is cut off to save the battery.

Performing OTDR acquisitions

Once the configuration for acquisition and file storage has been defined, the instrument
is ready to launch an OTDR measurement.

Acquisition in Real Time mode

Principle of Real Time mode

Acquisition in real time must not be used if a precise measurement is required because
of the high noise level, but it is sufficient for rapid optimization of a connection and for
observing a fiber in process of utilization.

Performing an acquisition in Real Time mode

To carry out an acquisition in real time, after selection of the requisite acquisition param-
