026741W Huawei OptiX OSN Telecom System Card

The Huawei 026741W is an SSN1OUO8 optical interface unit designed for use in Huawei OptiX OSN series SDH/MSTP transmission equipment. This board provides eight-channel STM-1 optical interface capabilities, enabling high-capacity tributary signal access and processing within optical transport networks.

The SSN1OUO8 is deployed in Huawei’s OptiX OSN 3500, OSN 7500, and related synchronous digital hierarchy platforms. It serves as a key component for aggregating lower-rate optical signals and facilitating interconnection between network elements in metro and regional transmission networks.

This is a legacy product associated with Huawei’s earlier generation SDH/MSTP portfolio. While these platforms remain operational in many existing network deployments, they have largely been superseded by newer OTN and packet-optical technologies. The board remains relevant for maintenance, capacity expansion, and life-extension of installed OptiX infrastructure.
