Keep high-speed rack connections short, predictable, and easy to procure. This ENET compatible 100GBASE-CR4 QSFP28 direct attach copper cable is designed for 50 cm links between adjacent ports, making it a practical choice for top-of-rack and same-rack interconnects where optical modules are unnecessary. Built for RUCKUS (formerly Brocade) environments, it supports 100 GbE connectivity in a compact passive form factor that helps reduce power draw, heat, and bill-of-materials cost versus transceiver-and-fiber alternatives. The short 50 cm length is ideal when equipment sits in the same chassis row or adjacent rack position, where excess cable length only adds clutter. TAA compliance makes this cable easier to specify in regulated procurement environments. For infrastructure teams standardizing on QSFP28-based 100 GbE, it delivers the direct-attach simplicity that keeps deployments clean and serviceable while preserving the throughput expected from modern spine, leaf, and aggregation layers.
