    Overview

    Huawei TN11DCU11 Overview

    The Huawei TN11DCU11 is a carrier-grade dispersion compensation unit engineered for long-haul DWDM transport over G.655 fiber. Providing 20 km dispersion compensation across the 1525 nm to 1565 nm C-band, it stabilizes high-speed optical signals and extends link reach without regeneration. With low insertion loss, controlled dispersion slope, and LC/UPC interfaces, this module is ideal for service providers, data centers, and enterprise backbone networks in Asia, Europe, Africa, and North America seeking reliable optical performance.

    Product Applications Scenarios

    Service Providers
    TN11DCU11 enhances long-haul optical links, correcting dispersion so carriers can push higher bit rates over G.655 spans while avoiding costly regeneration sites and reducing backbone upgrade costs by up to 25%.
    Data Center
    Used in inter‑DC DWDM trunks, the module stabilizes high-speed wavelengths over regional fiber routes, minimizing latency penalties from dispersion and improving link margins for critical cloud workloads.
    Enterprise Network
    Enterprises running metro and national DWDM backbones can deploy TN11DCU11 to keep optical performance within design limits, extending fiber life and cutting backbone expansion CAPEX by up to 20%.
