100GBASE-CR4 QSFP100 Twinax Cable 2.5 m Arista Compatible

Move 100 GbE traffic with a direct attach cable built for short-reach infrastructure. This 100GBASE-CR4 QSFP100 to QSFP100 twinax copper cable is sized at 2.5 m for tight rack layouts, switch-to-switch links, and nearby high-speed connections where optical modules are unnecessary. Arista compatibility makes it a practical fit for enterprise environments standardizing on QSFP100 ports. The copper twinax design keeps the path direct, reducing component count and simplifying deployment compared with separate transceivers and fiber patching. For teams building dense leaf-spine or top-of-rack architectures, that translates into cleaner cable management and a lower cost per link. At 2.5 m, this cable is optimized for the short runs where passive copper performs best. It is a straightforward way to extend 100 GbE connectivity between adjacent devices while preserving the speed and reliability expected in production networks. Choose it when you need a compact, high-speed interconnect that fits the rack, fits the port, and fits the budget better than optical alternatives for short distances.
