    Overview

    Huawei QSFP-40G-CU3M Overview

    The Huawei QSFP-40G-CU3M is an enterprise-grade QSFP+ high speed direct-attach copper cable designed for short-range 40Gbps connections in modern data centers. With a compact 3-meter length and 100 Ohms impedance, it delivers reliable full-duplex data transmission between top-of-rack switches, servers, and storage. IEEE 802.3ba compliance and QSFP+38M compatibility ensure seamless integration, while the PVC jacket, metal connectors, and low 1.5W per end power draw support efficient, cost-effective indoor deployments.
