LR-LINK 10G SFP+ DAC 5m twinax cable with SFP+ connectors on both ends

LR-LINK

LR-LINK 10G SFP+ DAC 5m Twinax Cable network ethernet cable

SKU CH-HX46-EW1DA

A 5-metre SFP+ direct-attach copper cable carrying 10 Gb/s bi-directional links, compliant with 10GFC and SFF-8431, AC-coupled for low EMI and rated 0 to 70 °C operating

  • Up to 10 Gb/s bi-directional throughput for fast data transfer
  • AC coupled inputs and outputs reduce electromagnetic interference
  • Operates from 0 to +70 °C and stores from -40 to +85 °C
  • Compliant with 10GFC and SFF-8431 for broad compatibility
  • Single +3.3 V power supply ensures stable operation

High-Speed 10 Gb/s SFP+ Direct Attach Cable

This LR-LINK SFP+ DAC provides up to 10 Gb/s bi-directional data links for short-reach networking. It is built for server racks and storage arrays that use SFP+ ports and need a fixed 5 m copper link. The passive twinax design requires no external power beyond the port supply.

Passive Cooling and Low EMI in Standard Racks

The cable operates from 0 to 70 °C and stores from -40 to 85 °C without active cooling. AC coupled inputs and outputs reduce electromagnetic interference in dense patches. A single 3.3 V supply from the host port keeps power draw minimal and silent.

Replaces Optical Modules for Short Copper Runs

This passive twinax replaces SFP+ optics and patch cords when the link stays within the cable length. The jump is worth it when latency, cost and power must stay low and the 5 m reach satisfies the topology. It is not for links that exceed the fixed length or require media conversion.

Questions about this item

How do I plug this LR-LINK DAC cable into the SFP+ ports and what step is often missed?

Insert each SFP+ connector fully until the latch clicks, then remove the dust caps only at that moment; the cable is passive and draws +3.3 V from the port so no external power is needed.

What maintenance or replacement will this 5 m twinax cable need over time?

No scheduled maintenance is required; inspect the latch tabs and connector gold fingers if link errors appear, and replace the cable if the copper twinax is kinked or the housing cracks.

What is the first limit I will hit when running this cable at 10 Gb/s continuously?

The operating ceiling is +70 °C; sustained full-rate traffic in a hot rack can push the cable to that limit before signal integrity degrades.
