    Overview

    Huawei SL91SL1DA03 Overview

    The Huawei SL91SL1DA03 is a carrier-grade SL91 Series optical interface board designed for SDH/SONET transport networks. Featuring 2xSTM-1 ports over single-mode fiber, it uses the L-1.1 optical standard at 1310 nm to deliver stable 155M-class transmission up to 15 km. LC/PC connectors, low 15W power consumption, and hot swapping make it ideal for telecom service providers and enterprise backbones. With comprehensive alarms, performance monitoring, and rich diagnostic functions such as optical power measurement and PRBS tests, the SL91SL1DA03 simplifies maintenance while ensuring high availability.
