LEEBICHEN 1PACK 400G QSFP112 to QSFP112 DAC Cable for NVIDIA DGX Spark, 0.5m/1.64ft 30AWG Passive Direct Attach Copper Twinax, 400G Ethernet

Why it's a great deal

• Compatible with NVIDIA DGX SPARK: Connect two compatible DGX Spark systems through their QSFP network ports for high-speed inter-node communication. Suitable for desktop AI clustering, distributed inference, model development and fine-tuning workloads.

• UP TO 400GBPS CABLE CAPABILITY: QSFP112-to-QSFP112 direct attach cable compliant with the QSFP112 MSA and designed for 400G Ethernet applications. When used with DGX Spark, the system establishes its supported 200GbE direct connection.

• 0.5M 30AWG PASSIVE COPPER CABLE: The short 1.64ft twinax cable is designed for equipment positioned side by side or within the same rack. Its passive construction requires no separate optical transceivers and consumes no more than 0.125W.

• ETHERNET AND INFINIBAND SUPPORT: Supports 400G Ethernet and compatible InfiniBand EDR/HDR applications. Actual speed and protocol depend on the connected network card, switch, firmware and port configuration.

• HOT-PLUGGABLE AND QUALITY TESTED: Supports hot insertion and removal for easier installation. Each cable undergoes quality inspection for signal integrity and connection performance. Confirm that your equipment uses compatible QSFP112 ports before ordering.

• QSFP112 400G DAC Passive High-Speed Copper Cable / InfiniBand Cable, supporting HDR Ethernet and InfiniBand signals. Compatible with the NVIDIA DGX Spark Personal AI Supercomputer. Q112-400G-CU50CM high-speed stacking cable, passive direct-attach copper cable. Compatible with NVIDIA/Cisco/Huawei/Juniper/Mellanox/H3C/Intel and other fiber-optic communication equipment, network interface cards, servers and network switches.
