Arista 100GBASE-CR4 QSFP to QSFP Twinax Copper Cable, 2 m

Two meters of 100GbE copper is the offer of the Arista CAB-Q-Q-100G-2M. The title calls it a 100GBASE-CR4 QSFP to QSFP twinax cable, and the connectors are QSFP28.

That length helps when ports are a few rack units apart or in neighboring racks. Copper keeps the cost of the link down compared with two optics and fiber, and the cable is ready to plug in. Check that your switch and server both use QSFP28 ports before ordering, and measure the cable path including the bends. Send us the device models with your request if you want us to confirm the match.

Because the connectors are attached, planning is simple: confirm both devices have QSFP28 ports and measure the path. Available conditions are new, refurbished and used. New and refurbished list 1 year or 3 years of warranty, while used lists 90 days.
