Huawei WD22GTMUB GTMU gigabit transmission module unit for OptiX OSN equipment.

The Huawei WD22GTMUB is a GTMU (Gigabit Transmission Module Unit) board designed for use in Huawei OptiX optical transmission systems. This service processing board provides gigabit-level transmission capabilities for metro and backbone network applications.

The GTMU board is deployed within Huawei’s OptiX OSN (Optical Service Node) platform, supporting SDH/MSTP network architectures. It handles high-capacity data transmission and switching functions essential for carrier-grade telecommunications infrastructure.

This is a legacy board from Huawei’s established OptiX transmission portfolio. While newer platforms have since been introduced, the OSN series remains deployed across many operator networks requiring ongoing maintenance and expansion support.
