SSN1SLQ4A(L-4.1,LC) Huawei High Quality Interface Board
The SSN1SLQ4A(L-4.1,LC) Huawei is a robust STM-4 4-port optical interface board designed for high-capacity SDH transmission across metro and backbone networks. Each port supports 622 Mbps (STM-4) using the L-4.1 long-reach standard, enabling transmission distances up to 15 km over LC-type single-mode fiber.
Optimized for Huawei’s OptiX series — including OSN1500, OSN2500, and OSN3500 — the board is engineered for seamless service delivery, efficient multiplexing, and advanced error monitoring. Its hot-swappable design ensures easy maintenance without service interruption.
