Active Optical Cable CBO SFP28-AOC-5M 5 m — SFP28 direct-attach AOC, 25Gbps per lane

CBO SFP28-AOC-5M is a 5-meter active optical cable with SFP28 interfaces designed for short-reach 25GbE direct-attach connections. It links switches, servers and network interface cards that support SFP28, offering a fiber-based alternative to copper direct-attach cables. The cable provides low latency and immunity to electromagnetic interference while reducing weight and heat dissipation in high-density installations, making it suitable for data center uplinks, top-of-rack connections and other short-distance interconnects.

Advantages

The active optical design delivers consistent signal integrity over the 5 m distance and removes susceptibility to electromagnetic noise common with copper solutions. Its SFP28 form factor ensures compatibility with standard 25GbE SFP28 ports, while the lighter fiber construction eases cable management in dense rack environments. The product supports low latency operation and contributes to lower overall power and cooling needs compared with equivalent copper assemblies.

Suitable for

• 25GbE uplinks between switches and aggregation equipment
• Top-of-rack (ToR) interconnects in data centers
• Direct connections between servers and NICs with SFP28 ports
• High-density rack deployments requiring reduced cable bulk

Key specifications

• Connector type: SFP28 on both ends
• Data rate: 25 Gbps per lane (SFP28 standard)
• Length: 5 meters
• Cable type: active optical cable (AOC)
• Latency: low-latency fiber transmission suitable for short-reach links
• Immunity: resistant to electromagnetic interference
• Physical: lightweight, flexible fiber construction for high-density routing

How to use

Install the CBO SFP28-AOC-5M by inserting each SFP28 connector into the matching SFP28 port on your switches, servers or NICs until the latch engages. Ensure both endpoints support 25GbE SFP28 operation and that link settings on devices are configured for the desired speed and duplex. No additional transceivers or external power are required for the AOC; hot-plugging is supported in equipment that allows it. Verify link status via device LEDs or management interface after insertion.

Recommendations

Keep connectors clean and protected when not in use; avoid excessive bending of the fiber cable and maintain the minimum bend radius specified by your equipment guidelines. Use this AOC for short-reach 25GbE links within racks or between adjacent racks, and combine with appropriate monitoring and port configuration for optimal performance.
