1-Meter 100GbE QSFP28-to-QSFP28 Direct Attach Copper Cable
$ 39,48 Price excluding tax
The 1M 100GbE QSFP28-to-QSFP28 DAC Cable is a high-speed 100Gbps passive Direct Attach Copper (DAC) cable designed for short-distance data-center and high-performance networking connections. It uses QSFP28 connectors on both ends and is ideal for switch-to-switch and server-to-switch connections within the same rack.
Description
The 1-Meter 100GbE QSFP28-to-QSFP28 Direct Attach Copper Cable provides a cost-effective, low-latency solution for connecting compatible 100GbE QSFP28 ports.
The cable uses a passive copper/twinax construction, making it particularly suitable for short-distance, in-rack connections where high bandwidth and minimal latency are required. The QSFP28 interfaces support 100Gbps Ethernet, commonly using four 25Gbps electrical lanes.
Its compact 1-meter length helps reduce cable congestion in high-density server racks while providing direct connectivity between compatible switches, servers, storage systems, and network adapters.
If this is the Dell P7C7N version, Dell identifies it as a 100GbE QSFP28-to-QSFP28 passive copper DAC, 1 meter, with alternative part numbers 0P7C7N and DAC-QSFP28-100G-1.0M.
