Complete Connects SFP28 25G Direct Attach Copper (DAC) cable assemblies offer customers a high performance, cost effective I/O solutions for 25G Ethernet and 25G Fibre Channel applications.

DAC SFP28 to SFP28 Cables offer the lowest cost connectivity for 10GBASE-CU as well as a high port density and low power requirement. For short distances DAC cables offer a lower cost alternative to SFP28 Transceivers and fibre patch cables.

There are 2 versions of Direct Attach Copper Cable; passive and active. Passive DAC Cables enable connection up to 5m. Active DAC cables have an increased distance (to 10m) and also have a reduced size cable diameter. Note – Some equipment brand will only accept active DAC cables.

Each DAC cable is programmed prior to dispatch with correct code to ensure it is compatible with the brand of equipment. All Complete Connect DAC cables are fully tested for compatibility prior to dispatch and are MSA (Multi Source Agreement) compliant.

MSA Compliant

All our Direct Attach Copper (DAC) cables are built to MSA (Multi Source Agreement) standards and are extensively tested to ensure 100% compatibility with a huge range of leading switch and device manufacturers. Our SFP28 DAC cables are fully compliant with MSA SFF-8402 &  SFF-8432

Lifetime Performance Warranty

We are very confident in the performance and reliability of our DAC (direct attach copper) cables that we offer a lifetime performance warranty. This is combined with our outstanding service and support levels to ensure complete peace of mind.

Our programming & 3rd party brand compatibility

All our SFP28 DAC cables are coded with the correct EEPROM (electrically erasable programmable read-only memory) to match your manufacturers codes. Not all manufacturers require a code, only the ones that try to tie you into buying their optics at inflated prices. Complete Connect have a professional team who are able to engineer code and new firmware releases from manufacturers to ensure we offer up to date compatibility with all major OEM, switch, router and storage device vendors.
