  Jumper test

Jumper test method:
First open the light source and optical power meter, with the test connector to connect the light source and optical power meter for loss and insertion loss correction: first press the tester "CHANNEL" button, then press the second row of the second button to return correction, calibration After the loss of base for the 20db or so, and then by the optical power of the second key to insert loss to zero. Clearing the power meter The dBm value shown is the primary reference for measuring whether the light source is working properly. After removing the test connector head on the optical power meter, install the test adapter. With a calibration connector directly connected to the test adapter and optical power meter, this time the power meter shows the dB value is the test connector test connector insertion loss. From this value you can see that the test connector of the test connector is normal. The two connectors of the tested connector are wiped with alcohol and are connected to the test fiber connector, respectively. The resulting dB value is the insertion loss and return loss of the connector.
