Axiom Memory X66211B-3-AX 3m 100G QSFP28 Passive DAC Cable

Create a short-reach 100 Gigabit Ethernet connection between QSFP28-equipped devices using a passive direct-attach copper cable. This assembly supports 100GBASE-CR4, the four-lane copper Ethernet interface commonly used for high-bandwidth links between switches, servers, and storage equipment. Its QSFP28 termination provides a fixed cable connection rather than a pair of removable optical modules. At 3 m, the cable fits adjacent equipment in a rack or closely positioned racks where a copper interconnect is practical. Use it when both endpoints expose QSFP28 interfaces and require a 100GBASE-CR4 link. Passive construction means the cable does not perform signal conversion, making endpoint port compatibility and supported cable reach important considerations for the connected equipment. X66211B-3-AX carries NetApp-compatible QSFP28 port coding for deployments using compatible NetApp interfaces. The combination of 100GBASE-CR4 signaling, QSFP28 connectors, passive DAC construction, and a 3 m length distinguishes it as a short copper interconnect for 100 Gbps links rather than an optical transceiver or a longer-reach fiber assembly. It is suited to fixed point-to-point connections where cable length and endpoint compatibility are already defined.
