Our programming & 3rd party brand compatibility

All our Direct Attach Copper (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.
