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).

12
Disconnect the optical power meter and reconnect the fiber to the receive port of
LP1.1.
...................................................................................................................................................................................................
13
Remove the optical loop from the ODF and install a variable optical attenuator.
...................................................................................................................................................................................................
14
Increase the attenuation until the PDH analyzer reports single bit errors.
...................................................................................................................................................................................................
15
Decrease the attenuation a little until no errors are reported.
...................................................................................................................................................................................................
16
Wait approximately 5 minutes (no errors may occur).
...................................................................................................................................................................................................
17
Disconnect the fiber from the Line Port “input” at the physical NE port and measure
the optical output level (refer to Figure 7-2, “Line port connection to optical
distribution frame test” (p. 7-9)).
...................................................................................................................................................................................................
18
Verify that the requirements mentioned in the table below are met.
Result:
Receiver sensitivity ranges:

S4.1 1310 ≤ –28
L1.1 1310 ≤ –34
L1.2 1550 ≤ –34
L4.2 1550 ≤ –28
