400G OSFP-RHS to 400G OSFP-RHS Twinax Direct Attach Copper Cable, Passive DAC Cable, 4X 100G PAM4, 1-Meter, 30AWG

["This cable uniquely connects a standard OSFP-RHS port on the switch side to an OSFP-RHS port on the NIC side, enabling optimized thermal management for GPU servers. It provides reliable 400G data transmission in thermal managed environments.","Supports 400G Ethernet (4x 100G PAM4) and InfiniBand NDR. As a Passive Direct Attach Copper (DAC)​ solution, it requires no retimers or power, delivering high bandwidth with ultra low latency for intra rack connections up to 2 meters—ideal for AI training, HPC, and storage networks.","As a passive DAC, it draws <0.1W, significantly reducing thermal load in high density racks. This efficiency minimizes cooling overhead and supports sustainable data center operation.","10Gtek owns Compatibility LAB to meet the coding requirements for various brands of switches and routers. Each cable is individually tested before delivery."]
