Huawei SL91CSHUF CSHU Control and Switching Unit for OptiX OSN series optical transport systems.

The Huawei SL91CSHUF is a CSHU (Control and Switching Hub Unit) board designed for use in Huawei’s OptiX OSN optical transport network equipment. This system module provides essential control plane functions and cross-connect switching capabilities within the chassis, serving as a core component for managing traffic routing and system operations.

The CSHU board is typically deployed in Huawei OptiX OSN 3500, OSN 7500, or similar optical transmission platforms used in metro and backbone telecommunications networks. It handles system control, communication between boards, and switching functions critical to the operation of the optical transport node.

As part of Huawei’s established OptiX product line, the SL91CSHUF represents proven technology widely deployed in carrier networks. While newer generations of optical transport equipment are available, existing OSN installations continue to require spare and replacement boards to maintain network uptime and service continuity.
