## Summary description

Passive SFP28 direct attach copper (DAC) cable by Lightwin, model LWO-DAC-SFP28-0.5M-HPE, providing 25 Gbps connectivity between SFP28 ports. 0.5 m length suitable for short-reach interconnects inside racks or between adjacent switches and servers. Compatible with HP Aruba SFPs/XFPs as specified, offering low-latency, cost-effective twinax connectivity for data center top-of-rack and high-density network environments.

## Long 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.
