## Summary description

Lightwin LWO-DAC-SFP28-0.5M is a 25 Gbit/s SFP28 direct attach cable (DAC) for short-reach connections between SFP28 ports. Designed for server, switch and storage interconnects, it provides a fixed low-latency copper link suitable for high-speed networking, data center uplinks and top-of-rack aggregation where a short passive SFP28 cable is required.

## Long description

Lightwin SFP28 DAC direct attach cable 25 Gbit/s LWO-DAC-SFP28-0.5M is a 0.5 m passive SFP28-to-SFP28 copper cable engineered for short-reach high-speed links. It connects SFP28 ports on switches, servers and storage equipment to deliver a fixed low-latency 25 Gbit/s physical connection. The cable is supplied in black and is intended for applications where a reliable, cost-effective direct attach solution is required without the need for optical transceivers.
Advantages
The Lightwin 25 Gbit/s SFP28 DAC provides a stable electrical connection with low latency and predictable signal characteristics. Being a direct attach copper cable, it eliminates the need for separate optical modules and fiber patching, reducing component count and simplifying rack cabling. Its short 0.5 m length is convenient for top-of-rack and adjacent-rack connections, minimizing cable slack and improving airflow management in dense installations.
Suitable for
Short-reach interconnects between SFP28 ports on switches and servers
Top-of-rack (ToR) aggregation and spine/leaf uplinks within the same rack
Direct server-to-switch connections in data center and rack-mounted environments
High-speed storage network links requiring 25 Gbit/s electrical interfaces
When it may not be suitable
This passive DAC is intended for short-distance, direct copper connections and is not suitable for longer runs where optical fiber is required. It is not a field-replaceable transceiver and cannot be converted to an optical link; environments that require hot-pluggable optical transceivers, long-distance connectivity, or immunity to electrical interference should use appropriate fiber optic modules and fiber cabling.
Key specifications
Data rate: 25 Gbit/s
Cable type: Direct Attach Copper (DAC)
Connectors: SFP28 (male) to SFP28 (male)
Length: 0.5 m
Colour: Black
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port until the latch clicks into place. Ensure both devices support passive SFP28 DAC connections and are powered off or that hot-plugging is supported by your equipment according to vendor guidelines. After connection, verify link status on both endpoints and configure network interfaces and speeds as required by your switch or server operating system.
What to consider before purchase
Confirm that both devices support passive SFP28 DACs and the desired 25 Gbit/s electrical interface.
Check physical port spacing and rack layout to ensure a 0.5 m cable length is appropriate.
Verify that a passive copper solution meets your distance and electromagnetic environment requirements.
Ensure firmware and vendor compatibility if your switches enforce vendor lock or compatibility lists.
Usage recommendations
For reliable operation, use the cable for short, direct connections within the same rack or adjacent racks, avoid sharp bends and excessive pulling, and follow equipment vendor guidelines for hot-plugging and firmware compatibility checks before deployment.
