    Overview

    Huawei TNU3N402T53 Overview

    The Huawei TNU3N402T53 is a carrier-class line service processing board designed for high-capacity optical transport in metro and backbone networks. Delivering 2×100G coherent line rate over 50GHz channel spacing with LC optical interfaces, it enables efficient DWDM deployment across Asia, Europe, Africa, and North America. Advanced SDFEC2 forward error correction improves reach and resilience, while tunable wavelengths simplify sparing and planning. Hot-swappable installation, SNMP management, and OptiX OSN series compatibility make it ideal for distributors, integration partners, and end users building scalable optical infrastructures.
