Huawei WDM-OTN Equipment Test Procedure
In this topic, we take Huawei OSN 8800 as example to show you how to test the WDM/OTN equipment (Huawei OSN 6800 etc)Description
Interleaver Board(C Band)
Occupies three slots.
Can be substituted by TN12ILT.
The ITL board is mainly used to multiplex and demultiplex signals, and to detect online optical spectrum
Multiplexes/demultiplexes optical signals between C_ODD signals and C_EVEN signals.
Provides an in-service monitoring port (MON).
TN11ITL01 is a 40-channel Demultiplexing Board.TN11ITL01 part number is 03030GDY, some other version like TN12 with different system compatibility and feature supported. TN11ITL have feature code like 01, 04 and 06, different channels
