NTP-G43 Perform the ROADM Node Acceptance Test
Note Because the node is isolated and no line-side fibers are connected during the test, the power levels going
into the line-side components will not be the same as a real network setup. Therefore, if the ROADM
shelf does not contain OPT-BST and OPT-PRE amplifiers on both the east and west sides, you must
lower the OPT-PRE power thresholds so that it turns on properly. At the end of the test, you will run
automatic node setup to configure the node with the correct parameters for the network acceptance test.
Step 1 Make a copy of Table 4-2 and place it in a convenient location for reference throughout this procedure.
The table shows the 32WSS ports and the wavelengths assigned to them. The 32 wavelengths are divided
among four physical MPO connectors on the 32WSS card. Each MPO connector is assigned eight
wavelengths. In CTC, the MPO connector appears in the card view Provisioning > Optical Connector
tab. Each Optical Connector subtab represents an MPO connector. Ports 1 through 32 are the receive
(RX) ports; Ports 33 through 64 are the PT ports.
Purpose The ROADM node acceptance test verifies that the node is operating
properly before you connect it to the network. The test verifies that each
add/drop and pass-through port on the 32WSS and 32DMX card operates
properly and verifies the operation of the amplifiers. The test also checks
the power levels at each transmit and receive port to ensure that power loss
in the cabling is within tolerance.
Tools/Equipment A tunable laser or eight TXP cards covering the 32 C-band wavelengths
(see Table 4-1 on page 4-4)
An optical power meter or optical spectrum analyzer
2 bulk attenuators (10 dB) with LC connectors
