SFP28 direct-attach cable CBO SFP28-DAC-5M-MR-BL 5 m Male-to-Male 25 Gbit/s

CBO SFP28-DAC-5M-MR-BL is a 5-metre direct-attach copper cable with SFP28 male connectors on both ends that supports 25 Gbit/s data rates. It is designed for short-range, high-speed connections between compatible switches, network interface cards (NICs) and servers, providing reduced latency and a simplified cabling approach by eliminating the need for separate optical transceivers. The cable is suitable for dense rack environments and typical data centre topologies where reliable, short-reach 25GbE links are required.

Advantages

The direct-attach design offers lower latency and lower power consumption compared with optical transceivers plus patch cords, while maintaining full 25 Gbit/s throughput. Being a fixed copper assembly with SFP28 male connectors at both ends, it reduces component count and simplifies installation and inventory management. The 5 m length provides flexibility for rack-to-rack or within-rack connections without excess slack, and the construction is intended for consistent signal integrity over short distances.

Suitable for

• 25GbE uplinks between switches in data centre top-of-rack or leaf-spine architectures
• Direct connections from servers or NICs to switches for high-performance computing or virtualised environments
• Short-range rack-to-rack or within-rack links where optical transceivers are not required

Key specifications

• Connector type: SFP28 male to SFP28 male
• Rated data rate: 25 Gbit/s
• Cable length: 5 metres
• Media: direct-attach copper (DAC)
• Typical use range: short-reach / within-rack and adjacent-rack connections
• Interface compatibility: SFP28 ports on switches, NICs and servers supporting DAC

How to use

Insert each SFP28 connector into the corresponding SFP28 port on the devices to be linked, ensuring correct orientation and a secure latch engagement. Verify that both devices support passive or active SFP28 DAC connections as required by your hardware vendor. After physical installation, check link status and interface configuration in the device management interface and enable or configure the 25GbE port settings as needed for your network design.

Recommendations

Use this 5 m SFP28 direct-attach cable in short-reach scenarios inside racks or between adjacent racks; avoid using it for distances beyond its rated 5 m. Confirm vendor compatibility for SFP28 DAC assemblies to ensure reliable operation and consider proper cable routing to prevent sharp bends and mechanical strain on connectors.
