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

CBO SFP28-DAC-5M-HU-BL is a 5 meter SFP28 direct attach cable (DAC) with male-to-male connectors that supports a 25 Gbit/s data rate. It is designed for short-reach, high-speed connections between switches, servers and network interface cards (NICs). The passive twinax construction provides low latency and stable signal integrity for rack-to-rack and top-of-rack connections in data center environments where active optical transceivers are not required.

Advantages

The cable delivers a reliable 25 Gbit/s link over a fixed 5 m length with low power consumption and minimal propagation delay. Its male-to-male SFP28 fittings ensure direct compatibility with SFP28 ports on switches, servers and NICs, allowing plug-and-play installation. The twinax DAC format offers a cost-effective alternative to fiber transceivers for short-distance interconnects, reducing component count and simplifying cable management in dense rack installations.

Suitable for

• Short-reach 25 Gbit/s connections between switches in the same rack
• Server-to-switch direct links in data centers
• NIC-to-switch interconnects for high-performance computing and virtualization hosts
• Rack-to-rack connections within the same equipment room

Key specifications

• Length: 5 m
• Connector type: SFP28 male-to-male
• Data rate: 25 Gbit/s
• Cable type: Direct attach twinax (DAC)
• Typical use: Short-reach, passive connection for data center equipment

How to use

Insert each SFP28 connector into the corresponding SFP28 port on the two devices to be connected, ensuring the latch engages securely. No additional configuration or external power is required for passive operation; the devices will detect the link once both ends are seated. Route the cable to avoid sharp bends and mechanical stress, keeping it clear of airflow paths and moving parts to maintain performance and reliability.

Usage recommendations

Use this 5 m SFP28 DAC for short-distance links inside racks or between adjacent racks. Verify port compatibility with SFP28 interfaces and consult switch or server documentation for any vendor-specific compatibility notes. Avoid tight bends and excessive tensile force when installing to preserve signal quality and cable lifespan.
