10Gtek 400G QSFP112 to 400G QSFP112 Twinax Copper Passive DAC Cable, 1.5-Meter, 30AWG

["A high-speed, cost-effective Direct Attach Copper cable assembly for 400G short-reach interconnects. The passive design requires no retimers, delivering 400Gbps (4x 100G PAM4) connectivity with ultra-low power consumption for intra-rack and inter-rack links.","Supports 400G Ethernet (IEEE 802.3ck) and InfiniBand NDR protocols. Ideal for connecting 400G switches to servers, routers, or storage in high-density data center environments, enabling high-bandwidth AI, HPC, and cloud infrastructure.","As a passive DAC, it operates at <0.1W, generating negligible heat. This eliminates the need for active cooling on cables, reduces thermal load in crowded racks, and lowers overall power costs.","Fully compliant with QSFP112 MSA standards and CMIS management interface. Each cable is individually tested for signal integrity and mechanical reliability to ensure plug-and-play compatibility with major 400G platforms."]
