The QSFP-100G-CU3M is a passive twinax direct-attach cable that builds a 100GBASE-CR4 link between QSFP28 ports with no transceivers, no fiber, and essentially no power draw or latency.\u003c\/p\u003e\n\u003cp\u003eThese are real Cisco cables, the same assemblies Cisco ships for Nexus 9000 and Catalyst 9500 builds — not a coded compatible. Twinax is factory-terminated at both QSFP28 ends, so installation is two clicks and done.\u003c\/p\u003e\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e Cisco QSFP-100G-CU3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Type:\u003c\/strong\u003e 100GBASE-CR4 passive direct-attach copper (twinax), 30 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnectors:\u003c\/strong\u003e QSFP28 to QSFP28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 3 meters (9.8 ft)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eData Rate:\u003c\/strong\u003e 100 Gbps (4 x 25G NRZ lanes)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Refurbished — tested and verified\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eOnly need an in-rack run?
