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)


40-channel Demultiplexing Board (C_Even,196.00THz~192.10THz,100GHz,Thermal AWG,LC) occupies two slots on Huawei OSN6800 and OSN8800.

Can substitute for TN11D4001.

Supports demultiplexing, online optical performance monitoring, alarms and performance events monitoring.

Demultiplexes main path signal to a maximum of 40 channels of service.

Demultiplexes one multi-wavelength signal into 40 C_EVEN wavelength signals.

Provides an in-service monitoring port (MON). 

Detects the optical power and reports the alarms and performance events for the board.


TN12D4001 is a 40-channel demultiplexing board applied to Huawei OSN6800 and OSN8800. TN12D4001 part number is 03030NAB, some other version like TN11D40 with different system compatibility and feature supported, TN12D4001 can substitute for TN11D4001. TN12D40 have feature like 01 and 02, different channels. TN12D4001 demultiplexes one main path into 40 C_EVEN channels, and TN12D4002 demultiplexes one main path into 40 C_ODD channels.
