Active Optical Cable CBO SFP28-AOC-20M 20 m — SFP28 direct-attach, 20-meter

Active Optical Cable CBO SFP28-AOC-20M is a 20-meter SFP28 direct-attach optical link built for high-speed server, switch and storage interconnects. The pre-terminated SFP28 AOC integrates optical transceivers and a multimode fiber link into a single cable assembly, removing the need for separate transceivers and patch cords. Designed for 25/28 Gbps-class connections, this AOC delivers low latency and stable signal integrity over longer distances than copper direct-attach options, while reducing cable bulk and simplifying rack and cable management in data center and enterprise environments.

Advantages

This SFP28 AOC provides a single-piece solution that reduces installation time and potential points of failure compared with discrete transceivers and patch panels. Its optical construction offers lower electromagnetic interference susceptibility and extended reach compared to copper DACs of equivalent class. The pre-terminated design ensures consistent optical performance and simplifies upgrades or reconfigurations by eliminating on-site fiber termination and additional patching.

Suitable for

• 25/28 Gbps server-to-switch and switch-to-switch links
• Top-of-rack and end-of-row cabling in data centers
• High-performance storage area network interconnects
• Environments requiring reduced cable weight and improved airflow

Key specifications

• Connector type: SFP28 direct-attach active optical cable
• Length: 20 meters
• Data rate class: 25/28 Gbps-class link
• Physical format: pre-terminated duplex cable assembly with integrated transceivers
• Typical use: short-to-medium reach within data center racks and rows
• Signal characteristics: low latency, optical transmission with immunity to electromagnetic interference

How to use

Install the cable by inserting each SFP28 module end into the corresponding SFP28 port on your network devices until the latch engages. Verify link status through the host device indicators or management interface. The cable requires no separate transceivers or fiber patching; ensure panels and ports are compatible with SFP28 form-factor modules and that devices support the required 25/28 Gbps link speed. Handle connector ends by the housing to avoid contaminating optical surfaces and store the cable without sharp bends to preserve fiber integrity.

Recommendations

Use the AOC for intra-rack and inter-rack connections where 20 m reach meets layout needs, and maintain cleanliness of optical interfaces. Avoid tight bending radii and exposure to mechanical stress; follow device vendor guidance for supported SFP28 modules to ensure compatibility and stable operation.
