25G DAC Cable SFP28 to SFP28 Passive Twinax Cable

SVNK 25G SFP28 Direct Attach Copper (DAC) Cable

The SVNK 25G SFP28 DAC cable is a high-performance, cost-effective copper interconnect solution designed for short-reach 25G Ethernet and InfiniBand EDR applications. Constructed with precision twinax copper cables and factory-terminated fixed SFP28 connectors, it provides a reliable, low-latency alternative to optical transceivers and fiber solutions for intra-rack and adjacent-rack connectivity.

SVNK 25G SFP28 DAC cables support high-speed electrical signaling up to 25.78125 Gb/s per channel while consuming ultra-low power (<0.1 W). The passive copper architecture eliminates the need for active electronics, resulting in minimal heat generation, near-zero latency, and excellent signal integrity, even in high-density environments.

Fully compliant with IEEE P802.3by, SFP28 MSA, SFF-8402, and SFF-8432, SVNK DAC cables ensure seamless interoperability with leading switches, servers, storage platforms, and network interface cards.
