Extreme Networks 25G Passive DAC SFP28 0.5M — 25 Gbps SFP28

Keep 25 Gbps uplinks and spine-to-leaf connections running through maintenance windows and peak loads with a 0.5 m passive SFP28 direct-attach cable. Engineered for short-reach, high-density environments, this twinax assembly delivers deterministic latency and a compact routing profile that reduces cable bulk in top-of-rack and end-of-row deployments. Passive construction eliminates local optics and active power draw at the connector, lowering port power consumption while preserving link integrity for 25 Gbps signaling. Use this DAC where ports are adjacent or within the same rack and where length predictability and thermal control matter. Because it is a vendor-specific MSA SFP28 form-factor cable, it pairs cleanly with SFP28 ports and avoids introducing unnecessary optics costs—an efficient choice when optical transceivers would add hardware and operating expense without benefit.
