Chapter 4 Perform Node Acceptance Tests
DLP-G312 Verify the West ROADM Add/Drop Channels
Step 19
Click the
Performance > Optics PM > Current Values
tabs.
Step 20
In the Port 2 (Trunk) column, locate the RX Optical Power value. Verify that the value matches the
power in
, +/– 2 dBm. If the power values do not match (+/– 2 dBm), remove, clean, and replace
the cable connecting the TXP_MR_2.5G RX port to the east fiber patch panel DMX port for the tested
wavelength. See the
“NTP-G115 Clean Fiber Connectors” procedure on page 13-25
. Repeat this step. If
the power values still do not match (+/– 2 dBm) contact your next level of support.
Step 21
Repeat Steps
through
for the remaining wavelengths.
Step 22
Display the east 32WSS in card view.
Step 23
Click the
Maintenance
tab.
Step 24
Click the table cell under Operating Mode and choose
Not Assigned
from the drop-down list for all
wavelengths.
Step 25
Click
Apply
, then click
Yes
to confirm.
Step 26
Remove the TXP or tunable laser from the east side patch panel.
Step 27
Unplug the physical loopback fiber from the line TX and RX in the OPT-BST or OSC-CSM card.
Step 28
Return to your originating procedure (NTP).
DLP-G312 Verify the West ROADM Add/Drop Channels
Note
Throughout this task, west refers to Slots 1 through 8, and east refers to Slots 10 through 17.
Step 1
In node view, display the Alarms tab.
Step 2
Create a physical loopback on the west OPT-BST or OSC-CSM by connecting a fiber with 10-dB bulk
attenuator from the OPT-BST LINE TX port to its LINE RX port. For OPT-BST cards, connect a 10-dB
bulk attenuator to the fiber. (OSC-CSM cards do not require attenuation.)
Caution
Failure to use proper attenuation might damage equipment.
Purpose
This procedure verifies the signal flow through the west side of a ROADM
node for add/drop channels.
Tools/Equipment
A tunable laser or eight TXP_MR_2.5G cards covering the 32 C-band
wavelengths (see
An optical power meter or optical spectrum analyzer
2 bulk attenuators (10 dB) with LC connectors
