Local tests in OADM configuration in DWDM systems
Figure 3-13 Local test in OADM configuration in DWDM systems
Note:
B&W ports are provided by PIM10GE (on PP20G), 4P2G5SO, 8PSO,
1P10GSO units.
Note:
DWDM ports are provided by PIM10GE (on PP20G) and 1P10GSO units
[also refer to “DWDM Commissioning Overview” (p. 3-39) ].
Note:
Insert an X-dB optical attenuator, according to the client/B&W interface used.
Perform the procedure previously described in “Local tests in OADM configuration in
DWDM systems” (p. 3-45) for both EAST and WEST sides of the OADM configuration.
Only the added and dropped channels have to be checked.
If present, the pass-through channels will be tested in link test (End-to-end), described in
“Link tests in DWDM systems” (p. 3-46) .
