Blue Cable Co 100GbE QSFP28 passive direct attach copper (DAC) cables are a power-efficient, plug-and-play alternative to optical fibre for short-reach 100G connections between QSFP28 ports, compatible with NVIDIA Mellanox platforms. Available in lengths from 1m to 5m, cables up to 2m operate as CA-25G-N (no FEC required) for low-latency deployments, while 2.5m to 5m variants are CA-25G-L and require RS-FEC to be enabled on the host. All variants feature an LSZH jacket and halogen-free PCB construction, and are backed by Blue Cable Co’s 5-year advanced hardware replacement warranty.
