2 metre SFP+ passive twinax cable

This 10Gtek SFP+ Direct Attach Copper cable provides a 10.3 Gb/s link over 6.56 ft of 30 AWG twinax. It replaces two optical modules and a fibre patch cord with a single passive copper assembly for rack-to-rack or intra-rack connections. The cable is programmed for compatibility with Cisco SFP-H10GB-CU2M, Ubiquiti UniFi and Fortinet equipment.

Best for short low-power 10 GbE links

Network engineers who need a low-cost, low-power 10 Gigabit Ethernet connection between adjacent switches or servers inside a rack will suit this cable. Buyers who require longer runs beyond the 3 metre passive limit, or who must connect Intel NICs at distances over 3 metres, should look at active or 24 AWG alternatives instead.

Factory-tested signal integrity

Each unit passes TDR and VNA measurement on an automated line that includes laser cutting, aluminium shielding stripping, automatic soldering and UV curing. The built-in EEPROM over I2C stores the compatibility codes so the link negotiates immediately on supported Cisco, Ubiquiti and Fortinet ports.

Questions about this item

What SFP+ ports must my switches or NICs provide for this 2-metre passive twinax cable to work?

The cable plugs directly into standard SFP+ cages on both ends; each side must present an SFP+ receptacle that accepts a passive direct-attach copper assembly.

Will the 30 AWG construction limit link stability if I keep older 10 GbE gear that expects longer passive runs?

At 2 metres the 30 AWG cable meets the 10.3 Gb/s specification; instability only appears on passive runs beyond 3 metres with certain Intel NICs or beyond 5 metres on some Cisco switches.

How can I verify the link is running at the rated 10.3 Gb/s after I connect the cable?

Check the switch or NIC management interface: the port should report a 10 Gb/s link with no errors, and the SFP+ EEPROM data will show the 10GBase-CU compliant cable identifier.
