Product information

Description

Lightwin SFP28 DAC cable 25Gbps LWO-DAC-SFP28-0.5M-HPE is a passive direct attach copper cable designed to connect SFP28 ports over a short reach. The 0.5 m twinax assembly provides a fixed, low-latency 25 Gbps electrical link for high-density rack environments, top-of-rack interconnects and adjacent switch-to-server connections. The cable uses SFP28 male connectors on both ends, comes in black, and is suitable for use where short, cost-effective, and power-efficient connectivity is required.

Advantages

The Lightwin passive SFP28 DAC delivers 25 Gbps throughput with minimal power consumption and negligible protocol conversion since it is a direct copper link. Its short 0.5 m length reduces signal attenuation and crosstalk in rack-to-rack or switch-to-server scenarios, while the pre-terminated SFP28 connectors simplify installation and reduce the need for transceivers. The product’s compatibility with HP/Aruba SFP devices and its twinax construction make it a cost-effective option for dense data center deployments.

Suitable for

  • Top-of-rack (ToR) switch to server connections within the same rack
  • Adjacent switch-to-switch interconnects in high-density cabinets
  • Short-reach patching in network racks and blade chassis
  • Environments where low latency and reduced power draw are important

When it may not be suitable

This passive DAC cable is intended for very short distances; it is not suitable for long-reach or campus links that require fiber optics or active transceivers. It also may not be compatible with devices that do not support SFP28 electrical interfaces or with equipment that enforces vendor-locking on third-party direct attach cables.

Key specifications

  • Cable type: passive direct attach copper (DAC)
  • Data rate: 25 Gbit/s
  • Connector type: SFP28 male to SFP28 male
  • Length: 0.5 m
  • Colour: black
  • Use case: short-reach, rack-level connectivity

How to use

Install the Lightwin SFP28 DAC by inserting each SFP28 connector into the corresponding SFP28 port on the two devices to be linked, ensuring the retention latch engages. No additional transceivers, power sources, or configuration are required beyond standard port enablement and network configuration on the connected devices. Verify link status through the host device LEDs or management interface and ensure firmware or switch settings allow passive DAC operation if vendor compatibility checks are present.

What to consider before purchase

  • Confirm both devices have SFP28 ports and support 25 Gbps passive DAC connections
  • Verify vendor compatibility or firmware requirements to avoid vendor-lock issues
  • Ensure 0.5 m length matches rack layout and clearance for intended placement
  • Assess whether a passive solution meets thermal and power constraints in your environment

Usage recommendations

Use this 0.5 m SFP28 DAC for intra-rack and adjacent-rack links where short, high-speed, low-latency connections are required. Avoid excessive bending at the connector heads and keep the cable within recommended bend radius. Check device port LEDs and system logs after installation to confirm stable 25 Gbps operation.
