400G OSFP to OSFP DAC Cable 0.5m (1.64ft), Flat Top Passive Direct Attach Copper Twinax, 4x100G PAM4, for Compatible 400GbE Ethernet Switches and Network Adapters

400G ETHERNET CONNECTIVITY Supports 400GbE connections using 4x100G PAM4 signaling. Designed for short-distance links between compatible Ethernet switches and network adapters in data centers, AI clusters and H-PC environments.
OSFP FLAT TOP CONNECTORS Features OSFP flat-top connectors on both ends for equipment designed to accept this connector style. Verify your devices port and cooling requirements before ordering.
PASSIVE COPPER DAC Integrated twinax copper cable and connectors provide a direct connection without separate optical transceivers or an external power supply. A practical solution for short-reach Ethernet connections.
0.5M SHORT-LENGTH DESIGN The 0.5m (1.64ft) length suits closely positioned equipment, helping reduce excess cable and keep rack connections organized. Check the required routing distance and allow room for gentle cable bends.
CHECK DEVICE COMPATIBILITY Requires compatible OSFP ports, supported 400GbE operation and matching cable coding at both ends. This cable does not convert Ethernet to InfiniBand. Confirm the exact switch or adapter model before purchase.
