2 Checking Tail Fiber Connection

OUT port
To check tail fiber connection, you need to check the deviation of the optical power between an optical interface on the
board and the peer interface on the ODF. If the optical power meter reads a value less than or equal to 1 dB, it
indicates that the tail fiber connection is correct. Otherwise, check the fiber.
If the fiber is connected through a flange, the deviation should be less than 2 dB.
When using an optical power meter during a test, you are recommended to record the launched optical power of each
optical interface and check whether the launched optical power is normal.
Consult the project supervisor or software engineer and determine whether it is necessary to test the received optical
power by using an optical power meter, with an intention to check whether the received optical power is normal.
