SSN1SLQ4A(L-4.2,LC) Huawei Brand New 4-Port Interface Board
The SSN1SLQ4A(L-4.2,LC) Huawei is a 4-port STM-4 optical interface board built to deliver high-speed optical transmission at 622 Mbps per port. Designed for Huawei’s SDH-based MSTP platforms, this board uses L-4.2 standard transmission (up to 40 km reach) via LC-type single-mode fiber interfaces. It ensures robust and reliable service delivery in metro core and aggregation networks.
Fully compatible with Huawei OSN1500, OSN2500, and OSN3500 transmission platforms, the SSN1SLQ4A is engineered for carrier-grade performance, providing seamless SDH signal termination, loopback testing, and real-time performance monitoring.
