Product information

Description

The Lightwin SFP28 DAC Cable LWO-DAC-SFP28-1M is a 25 Gbps direct attach copper cable designed to connect two SFP28 ports directly. At 1 metre length and with SFP28 male connectors on both ends, this black DAC cable offers a low-latency, power-efficient physical link suitable for short-reach interconnects in racks and server rooms. It is intended for environments where fiber transceivers are unnecessary and a cost-effective copper connection between compatible SFP28 ports is preferred.

Advantages

This direct attach copper cable provides 25 Gbps throughput with minimal latency and reduced power consumption compared with active optical solutions. Its fixed 1 m length simplifies rack planning for top-of-rack and server-to-switch links, and the SFP28 male connectors ensure plug-and-play compatibility with devices that support SFP28 modules. The black cable jacket offers a neutral appearance that fits standard cabling runs.

Suitable for

  • Top-of-rack switch to server connections
  • Short-reach links within data center racks
  • Direct connections between NICs and switches supporting SFP28
  • Environments where low latency and low power consumption are priorities

When it may not be suitable

This DAC cable is intended for short-reach applications; it is not suitable for long-distance links between separate rooms or buildings. It requires devices with SFP28 ports on both ends and will not work with equipment that lacks SFP28 compatibility or requires fiber transceivers.

Key specifications

  • Data rate: 25 Gbps
  • Cable type: Direct Attach Copper (DAC)
  • Connectors: SFP28 male to SFP28 male
  • Length: 1 m
  • Colour: Black

How to use

Ensure both devices support SFP28 modules and are powered down according to the equipment vendor guidelines if hot-plugging is not supported. Insert each SFP28 connector into the corresponding SFP28 port until it seats and latches. After connection, verify link status through device LEDs or management interfaces and configure speeds or interface settings as required by your network equipment.

What to consider before purchase

  • Confirm both endpoints have SFP28-compatible ports
  • Assess whether 1 m length meets rack layout and cable management needs
  • Verify that a copper DAC meets your distance and electromagnetic environment requirements

Usage recommendations

Use the Lightwin 25 Gbps SFP28 DAC for short, direct interconnects within the same rack or adjacent racks. Avoid excessive bending near the connectors and follow equipment vendor guidance for hot-plugging and link configuration to ensure reliable operation.
