## Summary description

Direct attach copper cable (DAC) Lightwin LWO-DAC-SFP28-3M-HPE provides a 25 Gbit/s SFP28 to SFP28 connection over a 3 m fixed twinax link. Designed for short-reach interconnects in data centers and network racks, it is compatible with HP Aruba SFP and XFP ports and offers a low-latency, cost-effective solution for server-to-switch and switch-to-switch links.

## Long description

The Lightwin 25GbE SFP28 to SFP28 DAC Cable LWO-DAC-SFP28-3M-HPE is a fixed twinax direct attach copper cable designed for short-reach connectivity in racks and data center topologies. With a 3 m length and SFP28 connectors on both ends, it supports 25 Gbit/s links and is compatible with HP Aruba SFP and XFP ports. The cable is supplied in a black jacket and provides a low-latency, cost-efficient option for server-to-switch and switch-to-switch connections where fiber transceivers are not required.
Advantages
This DAC cable delivers 25 Gbit/s bandwidth with minimal latency and power consumption compared with optical solutions, while offering a lower total cost of ownership for short-distance links. The fixed 3 m twinax construction simplifies installation in rack environments and eliminates the need for separate transceivers, reducing component count and simplifying inventory. Compatibility with HP Aruba SFP/XFP ports ensures straightforward interoperability in mixed vendor deployments where these port types are supported.
Suitable for
 Short-reach server-to-switch connections inside the same rack or adjacent racks
 Switch-to-switch uplinks within data center rows or pod architectures
 High-performance networking environments requiring 25GbE links with low latency
 Environments aiming to reduce power and transceiver costs for short links
When it may not be suitable
This direct attach copper cable is intended for short distances; it is not suitable for long-reach links or routed connections between distant rooms or buildings. Environments that require optical isolation, very long runs, or flexible patching with separate transceivers should use optical fiber and SFP28 optics instead.
Key specifications
 Data rate: 25 Gbit/s
 Cable type: Direct attach copper (twinax)
 Length: 3 m
 Connectors: SFP28 male to SFP28 male
 Colour: Black
 Typical use: Short-reach, rack-level interconnects
How to use
Install the Lightwin SFP28 DAC by inserting each SFP28 connector into the corresponding SFP28 port on your switches or servers until the connector latches. Ensure devices are powered down or that hot-plugging is supported by your hardware and operating system before insertion if required by your change control policies. Verify link status and speed in your network device management interface and confirm 25GbE operation. Route the cable within the rack to avoid sharp bends and minimize strain on the connectors.
What to consider before purchase
 Confirm your switches/servers support SFP28 ports and 25GbE operation
 Verify compatibility with HP Aruba SFP/XFP port firmware and vendor interoperability notes
 Assess cable length needs—3 m is intended for in-rack or adjacent-rack links
 Decide between DAC and optical solutions based on distance, flexibility, and power considerations
Usage recommendations
For best results, use this 3 m DAC for connections inside the same rack or between adjacent racks, avoid tight bends (maintain gentle loop radii), and keep cable runs clear of high-heat sources. Check device link settings after installation and maintain firmware updates on HP Aruba equipment for ongoing compatibility.
