Huawei 022371 OMUb Optical Multiplexer Unit for DWDM transmission systems.
The Huawei 022371 OMUb is an Optical Multiplexer Unit designed for Dense Wavelength Division Multiplexing (DWDM) optical transmission systems. This board performs optical signal multiplexing functions, combining multiple wavelength channels onto a single fibre for high-capacity long-haul transmission.
The OMUb is deployed within Huawei’s optical transport network (OTN) platforms, typically the OptiX series of DWDM equipment. It serves as a critical component in the wavelength multiplexing chain, enabling carriers and enterprises to maximise fibre utilisation across metro and backbone networks.
This unit is part of Huawei’s established optical networking portfolio. As network operators continue to maintain and expand legacy DWDM infrastructure, demand remains for replacement and expansion boards to support existing deployments.
