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

CBO SFP28-DAC-5M-DL-BL is a 5 meter direct attach copper (DAC) cable with SFP28 male connectors on both ends, engineered for 25 Gbit/s short-reach interconnects. The cable provides a fixed, low-latency connection between compatible SFP28 ports in switches, network interface cards (NICs) and servers without the need for separate transceivers. Its passive copper construction is optimized for rack-to-rack links and other data center applications where cost-efficiency and reliable performance are required.

Advantages

The SFP28 male-to-male DAC delivers 25 Gbit/s line rate with minimal latency and reduced power consumption compared to optical transceivers. Its integrated connectors eliminate the need for hot-pluggable modules, simplifying installation and inventory management. The fixed 5 m length ensures predictable signal integrity for short-distance links, while the copper design offers a cost-effective alternative to fiber for intra-rack and short inter-rack connections.

Suitable for

• Short-range interconnects between switches in the same rack
• Direct connections from NICs to switches or servers
• Rack-to-rack links in data centers and server rooms
• Low-latency paths for storage and high-performance computing clusters

Key specifications

• Connector type: SFP28 male to SFP28 male
• Length: 5 meters
• Data rate: 25 Gbit/s
• Medium: Direct attach copper (passive)
• Typical applications: Short-reach data center links, server and switch interconnects

How to use

Install the DAC by inserting each SFP28 connector into the corresponding port until it seats firmly; no separate transceivers are required. Verify that the connected devices support SFP28 passive DACs and 25 Gbit/s operation, then enable the appropriate port configuration in the switch or host operating system. Avoid kinking the cable or bending it beyond the manufacturer’s recommended radius to maintain signal integrity.

Recommendations

Use this 5 m SFP28 DAC for short-distance links inside racks or between adjacent racks. Ensure both endpoints explicitly support passive SFP28 DACs at 25 Gbit/s; check device compatibility lists when available. For longer distances or fiber-based infrastructure, consider optical transceivers with appropriate fiber cabling.
