SFP28 Direct Attach Cable CBO SFP28-DAC-5M-NK-BL 5 m Male-to-Male 25 Gbit/s

The BlueOptics SFP28 Direct Attach Cable CBO SFP28-DAC-5M-NK-BL is a 5-meter male-to-male copper assembly designed for 25 Gbit/s links. Engineered for short-reach, high-throughput interconnects, this fixed-length SFP28 DAC provides a low-latency, low-power alternative to optical modules for direct connections between switches, network interface cards (NICs) and servers. The plug-and-play design requires no external transceivers or fibre terminations, simplifying rack-to-rack and top-of-rack deployments in data center and enterprise environments.

Advantages

This direct attach cable delivers predictable signal integrity and minimal latency for 25 Gbit/s links while consuming less power than active optical solutions. Its fixed 5 m length removes the need for separate transceivers and reduces inventory complexity. The male-to-male SFP28 connectors support standard hot-plug operation and provide a straightforward installation process. The copper construction offers robust performance for short-range connections with consistent throughput and reliability.

Suitable for

• Short-range 25 Gbit/s connections between switches in data center racks
• Direct links from network interface cards (NICs) to servers
• Top-of-rack to aggregation switch uplinks where distance is within 5 m
• Environments seeking low-latency, power-efficient interconnects

Key specifications

• Transmission rate: up to 25 Gbit/s
• Cable length: 5 meters
• Connector type: SFP28 male-to-male
• Media: direct attach copper (DAC)
• Form factor: fixed-length, no external transceivers required
• Typical use range: short-reach data center and enterprise links

How to use

Insert each SFP28 connector into the corresponding SFP28 port on network devices until the latch engages; ensure both ends are seated firmly to establish a reliable electrical connection. No additional configuration is required on most modern switches and NICs — devices will detect the direct attach cable and enumerate the link. Verify link status and speed in the device management interface and monitor for any port-specific alarms. For safe handling, avoid sharp bends near the connectors and route the cable to prevent strain on ports.

Recommendations

For optimal performance, use this 5 m DAC for intra-rack or adjacent-rack connections where distances do not exceed the specified length. Keep cable runs clear of sources of electromagnetic interference and secure cords to prevent accidental unplugging; check device compatibility lists for SFP28 copper modules when deploying across heterogeneous hardware.
