022NVL Huawei OptiX OSN System Module

The Huawei 022NVL is a TNS1PIU01 Power Interface Unit (PIU) designed for use in Huawei’s OptiX OSN series optical transmission platforms. This board provides power distribution and interface functionality within the equipment shelf, managing the conversion and supply of DC power to system components and ensuring stable operation of the transmission node.

The TNS1PIU01 is typically deployed in OptiX OSN 1500, OSN 2500, or OSN 3500 wavelength division multiplexing (WDM) and SDH/MSTP transmission systems. These platforms are widely used in telecommunications backbone networks, metro aggregation, and enterprise private network applications where reliable optical transport is essential.

This is a legacy product from Huawei’s established OptiX transmission portfolio. While newer platforms have since been introduced, the OSN series remains in active service across many operator and enterprise networks globally, sustaining demand for replacement and spare components.
