QSFP28 to QSFP28 100GbE DAC

Dell 470-ABQE-RFB is a refurbished QSFP28 direct-attach copper cable for connecting active network equipment in a 100GbE setup. Its twinax construction provides a direct cable link between compatible QSFP28 ports.

The cable is 3 m long and has a male QSFP28 connector at each end. As a passive 100GBase DAC, it is intended for short interconnects between network devices, without a separate optical cable assembly.

Dell lists systems including PowerEdge R640 and PowerSwitch S4128 among compatible equipment. The refurbished item is identified by MPN 470-ABQE-RFB.
