The Huawei OptiX OSN 3500 is a highly flexible, carrier-class intelligent optical transport platform, widely adopted across global telecom networks for its reliability and multi-service capabilities. Designed as part of Huawei’s OptiX OSN series, the OSN 3500 serves as a core component in metro and backbone transmission networks, offering robust performance in SDH (Synchronous Digital Hierarchy) environments while also supporting packet-based services. This makes it an ideal solution for operators seeking to converge legacy and next-generation services within a single, compact chassis.
Built to support a wide range of interfaces — including PDH, SDH, Ethernet, ATM, and WDM — the OSN 3500 allows for seamless integration into existing infrastructures while enabling smooth migration toward all-IP networks. With high-density service boards and a scalable architecture, it offers network operators the flexibility to expand capacity and service delivery without significant hardware replacement or network redesign. Its intelligent control plane, advanced protection mechanisms, and simplified O&M tools also help reduce operational costs and improve service reliability.
