10Gtek 10G SFP+ DAC Passive Twinax Cable 2m

SKU CH-N73D-H4G0R

A 2-metre passive twinax cable with SFP+ connectors for 10 GbE direct-attached links between switches, servers or NICs

  • Cable categoryTwinaxial
  • Overall length6.56 ft (2 m)
  • Product colorBlack
  • Delivers 10 GbE connectivity with passive SFP+ direct attach copper
  • 2-metre twinax length suits short-range rack and server links
  • AWG30 high-purity anaerobic copper core ensures low latency and signal quality
  • Reinforced connector ends protect against bending stress for long service life
  • Broad vendor compatibility via SFF-8431 EEPROM including Cisco, Ubiquiti and Mikrotik

10G SFP+ Passive DAC Cable 2m

This passive direct-attach copper cable connects two SFP+ ports at 10 Gbps for storage, server and high-performance computing links. The 2-metre length suits adjacent rack equipment or short cross-connect runs. It is built for new deployments that need a low-latency twinax link without active optics.

Passive twinax distance limit

Passive copper twinax is specified for short-reach connections; the supplier lists available lengths from 0.82 ft to 16.4 ft. Beyond that range an active or optical cable is required to maintain signal integrity. This 6.56 ft assembly stays within the passive envelope.

SFF-8431 EEPROM compatibility

The cable uses an open SFF-8431 EEPROM so it works with any device that follows that standard. It is not compatible with Juniper, HP, H3C, Arista, Dell Force10, Extreme, Mellanox, Allied Telesis or Foundry equipment that expects proprietary coding.

Questions about this item

Should I pick the 0.5 m, 1 m, 2 m or 3 m version?

Choose the shortest length that reaches between your SFP+ ports; the range offered is 0.82 ft to 16.4 ft, so the 2 m cable covers runs up to 6.56 ft.

What does the 10 GbE rating deliver in a live link?

It provides a 10 Gbit/s direct copper connection between two SFP+ ports with low latency and low power draw, suited for NAS, SAN or HPC traffic.

Which interface standard governs the cable and what does it limit?

The cable follows the SFF-8431 specification, which defines the SFP+ electrical interface and caps the passive assembly at the lengths offered.
