## Summary description

Lightwin LWO-DAC-SFP28-1M is a 25 Gbps SFP28 direct attach copper cable (DAC) designed for short-reach, high-speed connections between SFP28 ports. It provides a low-latency, power-efficient direct link for switches, servers and NICs supporting SFP28 modules. Ideal for data center top-of-rack interconnects and server-to-switch links where fiber transceivers are unnecessary.

## Long 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.
