TN12D4001 Huawei High Quality 40-Channel Demultiplexing Board
The TN12D4001 Huawei Demultiplexing Board is a passive DWDM demux module designed to separate a single high-capacity DWDM optical signal into 40 individual ITU-standard channels. It is compatible with Huawei’s OSN6800 and OSN8800 WDM platforms, providing a reliable and high-performance solution for long-haul transmission and data center interconnection.
This unit uses Athermal AWG (Arrayed Waveguide Grating) technology, ensuring low insertion loss, high isolation, and zero power consumption for carrier-grade optical networks.
