4.4.2 Real –time test
When the OTDR test mode is set as real time test, users need to set the measurement range, pulse
width , and other parameters according to the length of the optical fibers to be tested; press the key
, OTDR can perform real time scanning test of the tested optical fiber link. The test curves in the
main operating window will be refreshed continuously until pressing the key
again, and then
OTDR will stop testing.
4.4.3 Average test
When the OTDR test mode is set to the average test, users need to set the range, pulse width, and
other parameter according to the length of the tested optical fibers; press down the
key, OTDR
can perform average test on the the tested optical fibre link according to the set test parameters and
the test curves in the main operating window will be subject to average processing until the average
number of times displayed ih the interface is equal to the set one, OTDR stops the testing. In the
average test process, press down the key
again, OTDR will immediately stop testing.
4.5 Description of test items of 5302 series OTDR
The test items of 5302 OTDR include average loss, connection loss and reflection loss.

4.5.1 Average loss test
At this time, OTDR can perform test on the distance between cursor A and cursor B, the loss between
them and the average loss of the optical fiber segment where cursors A and B are located. Through the
navigation key, the cursors A and B can be switched and the positions of them can be modified, so that
customers can observe the detailed characteristics of each fiber link distance.
