Two-pack SFP+ passive twinax cable

This two-pack supplies two 10G SFP+ to SFP+ direct attach copper cables, each 3.28 ft long. They link switches, routers, servers or NICs equipped with SFP+ ports for storage or high-performance computing clusters. The passive twinax construction targets very short reach links inside or between adjacent racks.

30AWG twinax with SFP+ ends

Each cable uses 30AWG twinaxial copper terminated in SFP+ connectors on both ends, replacing two optical modules and a patch cord for higher density and lower cost. The passive design draws no extra power and suits runs up to 3 metres at 10GbE or 1-8G Fibre Channel speeds. Compatibility spans Cisco, Fortinet, Ubiquiti, Netgear, D-Link, Supermicro and other listed vendors.

Low power passive operation

Passive twinax cables consume minimal power compared with active optical or 10GBASE-T alternatives, generating no heat of their own and adding no fan noise to the rack. Each unit is TDR and VNA tested in the manufacturer's signal integrity lab and individually verified on switches before shipment. The 30AWG gauge supports stable 10.3Gb/s transmission at the supplied 1-metre length.

Questions about this item

What data rate does the 10Gtek SFP+ passive twinax cable support?

The cable is rated for 10 GbE and carries serial data up to 10.3 Gb/s per lane.

What SFP+ port spacing or clearance does the 1-metre cable require?

Each end uses a standard SFP+ connector; the 3.28 ft length is designed for within-rack or adjacent-rack connections.

How do you install the SFP+ DAC cable and what common mistake should be avoided?

Insert each SFP+ module until it clicks into the switch or NIC port; a frequent error is not seating the latch fully, causing intermittent link.
