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

CBO SFP28-DAC-5M-QL-BL is a 5 m direct-attach copper cable with SFP28 male connectors on both ends, engineered for 25 Gbit/s short-range links. It connects switches, routers and servers directly without separate optical transceivers, enabling low-latency, power-efficient connections inside racks and between adjacent racks. The cable is intended for use in data centre topologies and high-density switch environments where reliable, high-speed point-to-point links are required.

Advantages

The SFP28 direct-attach cable offers a compact, plug-and-play solution that reduces component count by eliminating separate transceivers. Its fixed copper construction yields lower latency and reduced power consumption compared with optical modules that require powered optics. The 5 m length strikes a balance between flexibility and signal integrity for rack-to-rack and within-rack connections, while SFP28-compatible connectors ensure interoperability with equipment supporting 25 Gbit/s SFP28 ports.

Suitable for

• Short-range 25 Gbit/s links between switches and routers
• Server-to-switch connections inside racks
• High-density data centre top-of-rack and leaf-spine architectures
• Temporary or permanent rack-to-rack interconnects where optical transceivers are not required

Key specifications

• Connector type: SFP28 male to SFP28 male
• Length: 5 metres
• Maximum data rate: 25 Gbit/s
• Cable medium: direct-attach copper
• Typical use: short-reach, point-to-point links
• Latency characteristics: low-latency copper interconnect

How to use

Insert each SFP28 connector into the corresponding 25 Gbit/s SFP28 port on the network devices until the latch engages. Ensure ports and devices support SFP28 passive DAC connections and that link speed is configured appropriately on both ends. Route the cable to avoid excessive bending and mechanical stress; maintain manufacturer-recommended bend radius and secure the cable to prevent strain on the connectors. No additional modules or transceivers are required.

Recommendations

For reliable operation, use the cable in short-reach environments such as within racks or between adjacent racks and verify device compatibility with SFP28 passive DACs. Avoid tight bends, excessive pulling force and exposure to liquids or extreme temperatures. When deploying in dense cable runs, label both ends for easy identification and perform link testing after installation to confirm full 25 Gbit/s operation.
