## Summary description

Direct Attach Cable (DAC) Lightwin LWO-DAC-SFP28-1M-HPE is a 1 m SFP28-to-SFP28 passive copper cable supporting 25 Gbps links. Designed for short-range high-speed connections, it provides low-latency, energy-efficient interconnects between switches, servers and NICs and is compatible with HP Aruba SFP and XFP ports for data center and network rack applications.

## Long description

Lightwin SFP28 DAC Cable LWO-DAC-SFP28-1M-HPE is a 1 m passive copper direct attach cable that provides a 25 Gbps electrical link between two SFP28 ports. Designed for short-reach, high-density environments, this SFP28-to-SFP28 cable offers a cost-effective, low-latency interconnect for switches, servers and network interface cards. The cable is finished in black and is compatible with HP Aruba SFP and XFP ports for use in data center racks and network cabinets.
Advantages
This direct attach cable delivers a reliable 25 Gbps connection without the need for separate transceivers, reducing power consumption and lowering overall link cost. The passive copper design supports low latency and predictable signal characteristics over short distances, while the fixed 1 m length helps maintain neat cable management in high-density rack deployments. Compatibility with HP Aruba SFP/XFP ports simplifies integration into existing infrastructures that use these interfaces.
Suitable for (tasks / use cases)
Short-reach interconnects between top-of-rack switches and aggregation switches
Direct connections from switches to servers or storage nodes with SFP28 ports
High-density rack installations where low-latency, high-bandwidth links are required
Environments seeking power-efficient alternatives to optical transceivers for 25 Gbps links
When it may not be suitable
This 1 m passive DAC is intended for short-distance connections within the same rack or adjacent racks; it is not suitable for long-haul or campus links that require fiber optics. Because it is a passive copper cable, it does not include the optical transceiver functions needed for conversion to optical media or for connections over long distances.
Key specifications
Data rate: 25 Gbps
Cable type: Passive DAC (direct attach copper)
Length: 1 m
Connectors: SFP28 (male) to SFP28 (male)
Colour: Black
How to use
Insert each SFP28 connector firmly into the SFP28 cage of the corresponding network device until the latch engages. Ensure both devices are powered and configured for 25 Gbps links and that port settings match on both ends. Route the cable to avoid sharp bends and excessive strain; keep the 1 m length within the intended rack area to maintain signal integrity. If link does not come up, verify port compatibility with HP Aruba SFP/XFP-supported cables and check device firmware or configuration.
What to consider before purchase
Verify that both endpoints have SFP28-compatible ports and support 25 Gbps electrical connections.
Confirm compatibility with your switch and server vendor, specifically HP Aruba SFP/XFP port support.
Assess rack layout to ensure 1 m length is appropriate for your use case.
Consider whether a passive copper DAC meets distance and electromagnetic requirements compared with active copper or fiber options.
Usage recommendations
Use this 1 m SFP28 DAC for short, direct connections inside racks where 25 Gbps bandwidth and low latency are required. Ensure proper port compatibility and avoid tight bends; store and handle the cable to prevent connector damage.
