Stand-alone test procedures
Note: Subtract 0.50 dB per optical connection (for the suggested set-up 1.5 dB (3
connections)) and subtract 0.2 dB per fiber segment (0.4 dB for 2 fiber segments).
...................................................................................................................................................................................................
Disconnect the optical power meter and reconnect the fiber to the receive port of
12
LP1.1.
...................................................................................................................................................................................................
Remove the optical loop from the ODF and install a variable optical attenuator.
13
...................................................................................................................................................................................................
Increase the attenuation until the PDH analyzer reports single bit errors.
14
...................................................................................................................................................................................................
Decrease the attenuation a little until no errors are reported.
15
...................................................................................................................................................................................................
Wait approximately 5 minutes (no errors may occur).
16
...................................................................................................................................................................................................
Disconnect the fiber from the Line Port "input" at the physical NE port and measure
17
the optical output level (refer to
distribution frame test" (p.
