Line port connection to optical distribution frame test
...................................................................................................................................................................................................................................
Overview
This test checks the connections of the optical (STM-1 or STM-4) Line Ports. The
correct labeling on the ODF is checked by monitoring the source of the reported alarm.
The quality of the physical optical connections to the ODF is checked by measuring
the optical power and by performing a receiver sensitivity test.
Estimated duration
10 minutes per port.
Test setup
The following figure illustrates a possible test setup.
Procedure
Proceed as follows to perform the test:
...................................................................................................................................................................................................
1
Provision a cross-connection from the first tributary port TP1.1 to Line Port 1.
...................................................................................................................................................................................................
2
Set the Line Ports to “Not Monitored”.
...................................................................................................................................................................................................
3
Set the Alarm Reporting/Severity of STM*cNES (STM* Not Expected Input Signal)
alarm from reported “No” to “
Yes”. (* stands for “1” or “4”, depending on the port
type under test).
...................................................................................................................................................................................................
4
Install a fiber loop on LP1.1 on the ODF.
