About the Huawei QSFP-40G-CU3M Direct Attach Copper Cable
QSFP+ Direct Attach Copper Cable for 40 Gbps connectivity up to 3 meters: The Huawei QSFP-40G-CU3M is a passive direct attach copper (DAC) cable engineered for high-speed, short-reach interconnects in enterprise data center environments. This cable delivers 40 Gbps aggregate throughput across four 10 Gbps lanes, utilizing the 40GBASE-CR4 standard to enable cost-effective connectivity between Huawei CloudEngine series switches and compatible QSFP+ infrastructure without the overhead of active transceiver modules. Network engineers and IT procurement teams seeking reliable, low-latency fabric solutions will find this cable essential for dense switching architectures.
Built to IEEE 802.3ba 40GBASE-CR4 and SFF-8436 QSFP+ MSA specifications, the Huawei QSFP-40G-CU3M employs integrated EMI shielding within its QSFP+ connector housing to ensure signal integrity across its full 3-meter reach. As a passive copper solution, the cable draws no active power from transceiver circuitry, reducing overall infrastructure power consumption while maintaining 64B/66B encoding per lane. Operating across a temperature range of 0°C to 70°C with storage capability from -40°C to 85°C, this cable is designed for reliable deployment in standard and controlled data center environments. The SKU-HUAWEIQSFP40GCU3MDIRECTATTACHCABLE part number is your reference for sourcing.
