## Summary description

Lightwin LWO-DAC-SFP28-3M is a 25Gbit Direct Attach Cable (DAC) with SFP28 connectors on both ends for short-range high-speed interconnects. Designed for use with SFP28 ports, this passive copper cable provides low-latency, energy-efficient connectivity for switches, servers and network appliances in data centers and rack-to-rack links.

## Long description

Lightwin LWO-DAC-SFP28-3M is a 25 Gbit/s Direct Attach Cable (DAC) with SFP28 connectors on both ends, engineered for short-range, high-speed interconnects. The 3 m passive copper assembly is intended for direct connections between SFP28 ports on switches, servers and network appliances. The cable offers low latency and energy-efficient performance for data centre rack-to-rack links, server top-of-rack setups and short switch-to-switch links.
Advantages
This DAC delivers fixed-speed 25 Gbit/s connectivity with SFP28-compliant plug-and-play compatibility, reducing the need for separate transceivers. As a passive copper solution, it consumes no additional power for signal conversion and provides inherently low latency and predictable performance at short distances. The 3 m length offers flexibility for rack and cabinet layouts while maintaining reliable electrical signal integrity. The black jacket provides a discreet appearance and easy cable management in dense deployments.
Suitable for
 Short-range high-speed links between switches and top-of-rack servers
 Direct connections in data centre racks and cabinet-to-cabinet links
 Network appliances and servers with SFP28 ports requiring 25 Gbit/s
 Environments where low latency and power-efficient links are required
When it may not be suitable
This passive SFP28-to-SFP28 copper cable is designed for short-distance interconnects and is not suitable for long-distance runs; for connections beyond typical rack-to-rack ranges, optical transceivers and fibre cabling are preferable. It is a fixed-length, non-field-terminable assembly and cannot be used where adjustable or longer spans are required.
Key specifications
 Cable type: Direct Attach Copper (DAC)
 Nominal data rate: 25 Gbit/s
 Connectors: SFP28 male to SFP28 male
 Length: 3 m
 Colour: Black
How to use
Power off or follow hot-plug guidelines of your networking equipment if required by the vendor. Insert each SFP28 connector into the corresponding SFP28 port until it latches; ensure the cable is routed to avoid sharp bends and mechanical strain. Verify link negotiation and speed on the connected devices and consult switch or server interface status LEDs or management interfaces to confirm a 25 Gbit/s link. For best results, place the cable away from sources of electromagnetic interference and secure it with appropriate cable management accessories.
What to consider before purchase
 Confirm that both devices have SFP28 ports and support 25 Gbit/s direct attach copper cables
 Verify that a 3 m fixed-length passive DAC meets your rack layout and distance requirements
 Check vendor compatibility lists if the networking equipment requires certified or tested cables
Usage recommendations
Use this 3 m SFP28 DAC for short, high-performance interconnects where low latency and power efficiency are priorities. Avoid exceeding recommended bend radius, and consult equipment vendor documentation for hot-swap and compatibility guidance.
