LR-LINK 10G SFP+ DAC twinax cable, 3m, passive copper with SFP+ ends

LR-LINK

LR-LINK 10G SFP+ DAC Twinax Cable 3m

SKU CH-38Z4-R3CE6

A 3-metre SFP+ direct-attach copper cable carrying 10 Gb/s bi-directional links with AC-coupled I/O

  • 10 Gb/s bi-directional throughput for fast data transfer
  • Passive copper twinax construction for low-latency links
  • AC-coupled inputs and outputs maintain signal integrity
  • SFP+ to SFP+ direct attach eliminates separate transceivers
  • Plug-and-play installation works with standard SFP+ ports

High-Speed 10G SFP+ Direct Attach Cable

The LR-LINK SFP+ 10G Direct Attach Cable provides a 3-metre twinax copper link for 10 Gb/s bi-directional data transfer between SFP+ ports. Its passive, AC-coupled design requires no external power, offering a low-latency connection for high-demand networking applications. The plug-and-play construction simplifies deployment in compatible switches, servers, and storage arrays.

Suited for Short-Rack 10G Links; Not for Longer Runs

This cable suits installers connecting top-of-rack switches to servers within a single rack or adjacent cabinets where a three-metre reach is sufficient. It supports 10 Gb/s Ethernet and compatible storage protocols without the cost or power draw of optical transceivers. Buyers who need longer distances between racks or across data centre rows should look at active optical cables or transceiver-and-fibre combinations instead.

10 Gb/s Bi-Directional Passive Twinax Specification

The defining specification is the 10 Gb/s bi-directional data rate delivered over a passive twinax copper assembly with AC-coupled inputs and outputs. This electrical interface determines compatibility with SFP+ ports that support passive direct-attach cables and sets the practical reach limit for reliable signal integrity. Verify that your equipment lists passive copper support at this speed before purchasing.
