5.2.2 Manual mode test
Compared with the automatic mode, the measurement range and measurement
pulse need to be set independently. The measurement range is recommended to
be between 1.5-2 times of the actual length of the optical fiber, and the pulse size
can be selected by ourselves. (low pulse can improve the accuracy of events, but
the measurement range is small; high pulse can improve the measurement range,
but the accuracy of events will decrease)
The operation process of manual mode is as follows:
1. Clean the connector correctly
2. Connect a startup optical fiber between the tested equipment and the OTDR
port, and set the startup optical fiber length if necessary (refer to setting link
parameters in Section 4.3).
