Chapter 4 Perform Node Acceptance Tests
DLP-G89 Verify OADM Node Pass-Through Channel Connections
DLP-G89 Verify OADM Node Pass-Through Channel Connections
Step 1 Identify the first band connection configured in pass-through mode in both directions.
Step 2 Set the tunable laser or TXP_MR_2.5G card to the wavelength of the band to be tested. Refer to the
tunable laser manufacturer’s documentation or the “DLP-G268 Provision TXP_MR_2.5G Cards for
Acceptance Testing” task on page 4-4.
Step 3 Complete the “DLP-G90 Verify an AD-xB-xx.x Pass-Through Connection Power” task on page 4-50 for
the first pass-through connection.
Step 4 (Optional) Complete one of the following:
• If OSCM cards are installed, connect a power meter to the east OPT-BST LINE TX port and verify
that the east amplifier is turned on by the pass-through wavelength.
• If OSC-CSM cards are installed, complete the “DLP-G84 Verify the OSC-CSM Incoming Power”
task on page 4-44 for the east OSC-CSM card.
Step 5 Complete Steps 2 through 4 for all band connections configured in pass-through mode in both directions.
Step 6 If channel pass-through connections are not present, continue with Step 15. If channel pass-through
connections are present, continue with one of the following steps:
• If the pass-through channel connections use an AD-xC-xx.x card, continue with Step 7.
• If the pass-through channel connections use a 4MD-xx.x card, continue with Step 11.
Step 7 Tune the tunable laser on a wavelength (1 of 4) belonging to the channel to be tested.
Step 8 Complete the “DLP-G91 Verify an AD-xC-xx.x Pass-Through Connection” task on page 4-51 for the
first pass-through connection.
Step 9 (Optional) Complete one of the following:
• If an OSCM card is installed, connect a power meter to LINE TX port on the front-pane and verify
that the east OPT-BST amplifier is turned on by the pass-through wavelength.
• If an OSC-CSM card is installed, complete the “DLP-G84 Verify the OSC-CSM Incoming Power”
task on page 4-44 for the east OSC-CSM card.
Step 10 If the pass-through connections use a 4-channel multiplexer/demultiplexer (4MD-xx.x), continue with
Step 11. If not, continue with Step 15.
Step 11 Identify the first channel connection that is configured in pass-through mode using the 4MD-xx.x cards
in both directions.
Step 12 Tune the tunable laser on the corresponding wavelength.
Step 13 Complete the “DLP-G92 Verify 4MD-xx.x Pass-Through Connection Power” task on page 4-52.
Purpose This task verifies the pass-through channel connections during an OADM
node acceptance test.
Tools/Equipment A tunable laser or eight TXP_MR_2.5G cards covering the 32 C-band
wavelengths (see Table 4-1 on page 4-4)
