SSN1SLQ4A(S-4.1,LC) Huawei 4-Port STM-4 622M Interface Board
The SSN1SLQ4A(S-4.1,LC) Huawei is a high-performance STM-4 (622 Mbps) 4-port optical interface board designed for the Huawei OptiX OSN series, including OSN1500, OSN2500, and OSN3500 platforms. Supporting the S-4.1 short-reach specification (up to 2 km) over LC-type single-mode fiber, this board is ideal for metro aggregation, access rings, and carrier-grade SDH optical networks.
With built-in features such as loopback, alarm monitoring, and error detection, the SSN1SLQ4A ensures reliable and efficient transport of high-speed SDH services in both point-to-point and ring network topologies.
