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 for approximately 5 minutes (no errors may occur).
...................................................................................................................................................................................................
17
Disconnect the fiber from the Line Port “input” at the physical E port and measure the
optical output level (refer to
Figure 7-2, “Line port connection to optical distribution
frame test” (p. 7-8) ).

18 Verify that the requirements mentioned in the table below are met.
Result:
Receiver sensitivity ranges:
Interface Wavelength [nm] Receiver sensitivity [dBm]
S1.1 1310 ≤ –28
S4.1 1310 ≤ –28
L1.1 1310 ≤ –34
L1.2 1550 ≤ –34
L4.1 1310 ≤ –28
L4.2 1550 ≤ –28

19 Repeat test for Line Port 1.2, LP 1.3, LP1.4 , if applicable.
Cleaning up
The following tasks must be performed to clean up the system:
•
Disconnect the PDH analyzer
•
Disconnect the optical attenuator
