WP13DPUD Huawei OptiX OSN Series System Module

The Huawei WP13DPUD is a DC Power Distribution Unit (DPUD) designed for use within Huawei’s OptiX optical transmission and network equipment platforms. This unit provides regulated DC power distribution to shelf-mounted boards and modules, ensuring stable power delivery across the system chassis.

The DPUD board is typically deployed in Huawei OptiX OSN or Metro series transmission equipment, serving as a critical component in the power subsystem architecture. It distributes -48V DC power from the system’s power input to the various functional boards within the subrack.

As part of Huawei’s established transmission platform, the WP13DPUD is commonly found in carrier-grade optical network deployments. This unit may be considered legacy equipment depending on the specific system configuration, though it remains widely deployed in operational networks requiring maintenance or expansion.
