Cable SFP28 Direct Attach CBO SFP28-DAC-5M-FR-BL 5 m macho a macho 25 Gbit/s

The SFP28 Direct Attach Cable CBO SFP28-DAC-5M-FR-BL is a 5 m passive twinax cable with SFP28 male connectors at both ends, engineered for 25 Gbit/s short-range links. It enables direct, low-latency connections between servers, switches and storage devices in rack-to-rack or chassis environments. The cable supports plug-and-play operation and is intended for high-density data center topologies and network equipment interconnects where reliable, low-power transmission is required.

Advantages

This SFP28 direct attach cable provides a fixed low-latency electrical link for 25 Gbit/s applications without the need for separate transceiver modules, reducing power consumption and simplifying installation. Its passive design offers predictable performance for short distances and a robust mechanical connector interface minimizes signal loss and physical wear during repeated insertions. The 5 m length suits common rack-to-rack runs while maintaining signal integrity for 25 Gbit/s traffic.

Suitable for

• Short-range connections between network switches and top-of-rack servers
• High-density rack-to-rack interconnects in data centers
• Direct links between storage arrays and host adapters
• Environments requiring low-latency, low-power 25 Gbit/s links

Key specifications

• Connector type: SFP28 male to SFP28 male
• Data rate: up to 25 Gbit/s
• Cable type: passive twinax copper
• Length: 5 meters
• Typical applications: server, switch and storage interconnects
• Form factor compatibility: SFP28 port devices

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the devices until the latch engages. Confirm the link status on both devices and ensure firmware or operating system settings recognize the 25 Gbit/s connection. No external power or configuration is required for basic operation; follow vendor guidance for any device-specific compatibility checks. Avoid sharp bends and maintain recommended bend radius to preserve signal performance.

Recommendations

For reliable performance, use the cable in short-range data center interconnects and confirm compatibility with device vendors for passive SFP28 DACs. Keep the cable within its specified 5 m length, avoid excessive bending or crushing, and ensure proper airflow and rack management to prevent mechanical stress on connectors.
