Cabo SFP28 CBO 7Z57A03541-BO 3 m macho-macho 25 Gbit/s

The SFP28 Cable CBO 7Z57A03541-BO 3 m Male-to-Male 25 Gbit/s is a direct-attach copper cable designed for short-reach, high-speed interconnections. With a fixed 3 m length and SFP28 male connectors at both ends, this cable provides a reliable 25 Gbit/s link between switches, servers and network interface cards that support SFP28 ports. It is intended for rack-to-rack and within-rack connections in data centers and enterprise networks where compact cabling and predictable latency are required.

Advantages

This direct-attach SFP28 cable offers a cost-effective alternative to optical transceivers by integrating the connector and cable into a single assembly, reducing component count and power consumption. The cable’s fixed length and male-to-male SFP28 terminations simplify installation and help maintain consistent latency and signal integrity over short distances. Its compact form factor helps reduce cable clutter in dense rack environments.

Suitable for

• Short-reach connections between switches and top-of-rack devices
• Direct links from servers to network interface cards with SFP28 ports
• High-density cabling in data centers and server rooms
• Environments requiring low latency and predictable performance

Key specifications

• Connector type: SFP28 male to SFP28 male
• Data rate: 25 Gbit/s
• Cable length: 3 meters
• Type: Direct-attach copper (DAC)
• Typical use: Short-reach interconnects, within-rack and rack-to-rack

How to use

Install the cable by inserting each SFP28 male connector into the corresponding SFP28 port on networking equipment or server NICs. Ensure both devices are powered down or support hot-plugging per manufacturer guidance before insertion or removal. Verify that the connected devices are configured for 25 Gbit/s operation and check link status in the device management interface. Route the cable to avoid sharp bends and secure it to maintain airflow and prevent strain on the connectors.

Recommendations

Use this direct-attach cable for distances up to 3 meters in controlled ambient environments. Avoid excessive bending or pulling and keep the cable away from high-interference sources. For longer distances or different form factors, consider optical transceivers and fiber cabling.
