SFP28 DAC cable CBO SFP28-DAC-5M-IA-BL 5 m, male-to-male, 25 Gbit/s

Direct attach SFP28 DAC cable CBO SFP28-DAC-5M-IA-BL is a 5 m, male-to-male copper interconnect designed for 25 Gbit/s links. It provides a fixed, short-reach connection between compatible SFP28 ports on switches, routers and network adapters. The cable delivers low latency and reduced power consumption compared with active optical transceivers, making it suitable for high-density server racks and data center topologies where reliable short-distance connectivity is required.

Advantages

The cable supports 25 Gbit/s data transfer and is constructed for consistent electrical performance over a 5 meter distance. Its direct-attach form factor simplifies installation with plug-and-play compatibility for devices that accept SFP28 copper modules. The passive copper design lowers both link latency and power draw relative to optical modules, while providing a stable physical connection for point-to-point links in congested rack environments.

Suitable for

• Short-reach 25 Gbit/s connections between top-of-rack switches and servers
• High-density rack interconnects in data centers
• Connections between network adapters and switches for low-latency applications
• Cost-sensitive deployments that prioritize lower power consumption over long reach

Key specifications

• Data rate: 25 Gbit/s per link
• Length: 5 meters
• Connector type: SFP28 male-to-male direct-attach copper
• Form factor: passive direct-attach copper (DAC)
• Typical use: short-reach, fixed-link interconnects in rack and chassis environments

How to use

Insert each SFP28 connector into the corresponding SFP28 slot on the two devices to be linked, ensuring secure seating until the retention latch engages. No additional configuration is typically required at the cable level; devices should recognize the link and negotiate the appropriate speed. Verify link status on both endpoints and check for any vendor compatibility notes in device documentation. For safe handling, avoid sharp bends and secure the cable to prevent strain on the connectors.

Recommendations

Use this 5 m SFP28 DAC cable for short, high-speed links inside racks or between adjacent racks where 25 Gbit/s performance, low latency and lower power consumption are priorities. Avoid deploying the cable for longer distances beyond its rated length or in environments requiring electrical isolation that active optics provide.
