Active Optical Cable CBO SFP28-AOC-20M 20 m SFP28 AOC for 25Gbps links

Active Optical Cable CBO SFP28-AOC-20M is a factory-terminated 20-metre SFP28 AOC engineered for 25Gbps server, switch and data centre interconnects. The single-assembly optical cable provides low latency and power-efficient connectivity for environments with SFP28 ports, enabling reliable short-reach links within high-density racks or between adjacent racks. Its pre-terminated construction removes the need for separate transceivers and fibre patching, simplifying installation and rack cabling management.

Advantages

The cable delivers a compact, all-in-one optical connection that reduces equipment footprint and eliminates compatibility concerns associated with separate optical transceivers and patch cords. Its factory termination ensures consistent signal performance and repeatable insertion loss across installations. The AOC design provides lower power consumption compared with direct-attach copper alternatives at equivalent reach, and the single-cable assembly reduces crosstalk and mechanical strain on port connectors in high-density environments.

Suitable for

• 25Gbps server-to-switch connections within server racks
• Short-reach spine-to-leaf or top-of-rack interconnects
• Data centre aggregation links across adjacent racks
• High-density network deployments requiring predictable optical performance

Key specifications

• Connector type: SFP28 on both ends compatible with SFP28 ports
• Nominal data rate: 25 Gbps
• Length: 20 metres
• Transmission medium: multimode active optical assembly
• Latency: low insertion latency suitable for server and switch interconnects
• Power consumption: lower than equivalent copper direct-attach at the same reach
• Form factor: single-cable, factory-terminated assembly for simplified cabling

How to use

Install the AOC by inserting each SFP28 connector into the corresponding SFP28 port on your network devices until the connector latches. Ensure both devices are powered off or follow hot-swap procedures recommended by the device manufacturer when plugging into live ports. Route the cable to avoid sharp bends and excessive pull force; maintain the manufacturer’s recommended bend radius. Verify link status and network configuration on both endpoints after connection to confirm 25Gbps operation and link integrity.

Recommendations

For optimal performance, use the AOC in short-reach top-of-rack or adjacent-rack interconnects and avoid routing through switches of significantly different port designs. Keep connectors clean and handle by the connector body to prevent contamination. Monitor link integrity after installation and use standard fibre-optic cleaning tools if required.
