Active Optical Cable (AOC) CBO SFP28-AOC-50M 50 m — SFP28 25Gb/s direct attach fiber

CBO SFP28-AOC-50M is a 50-metre Active Optical Cable (AOC) with SFP28 connectors supporting 25 Gb/s data rates. Designed for short-range high-speed interconnects in servers, switches and data centre environments, the cable delivers low latency and immunity to electromagnetic interference while extending reach compared with copper direct attach cables. Its plug-and-play design integrates the optical transceivers into the cable assembly to reduce transceiver power consumption and simplify installation for dense rack deployments.

Advantages

The AOC construction provides stable 25 Gb/s performance over 50 metres with lower weight and improved thermal behaviour compared with equivalent copper solutions. Optical transmission makes the cable insensitive to electromagnetic noise sources common in data centres. Built-in SFP28 modules eliminate the need to install separate transceivers, reducing configuration steps and helping to control power draw at the port. The flexible assembly eases cable management in high-density racks and reduces the risk of signal degradation over the specified distance.

Suitable for

• Server-to-switch and switch-to-switch connections inside the same room or row
• Top-of-rack and end-of-row data centre interconnects
• High-density rack installations requiring reliable 25 Gb/s links
• Environments where electromagnetic interference must be minimised

Key specifications

• Connector type: SFP28 on both ends
• Nominal data rate: 25 Gb/s per channel
• Length: 50 metres
• Cable type: Active Optical Cable (integrated optical transceivers)
• Transmission medium: multimode optical fibre within AOC assembly
• Latency: low, suitable for short-range interconnects
• Electromagnetic immunity: inherent to optical transmission

How to use

Insert each SFP28 connector into the compatible port on the network devices until the latch engages, ensuring devices are powered according to their manufacturer instructions. No separate transceiver configuration is required in most modern switches and servers; the link is typically detected automatically. Route the cable to avoid sharp bends and excessive tension; maintain the minimum bend radius specified by the device vendor and avoid routing alongside high-heat sources. For first-time installations, verify link status and speed in the device management interface and consult the switch or server logs if the link does not come up.

Recommendations

Use this 50 m SFP28 AOC for reliable in-room 25 Gb/s connections where longer reach than copper DACs is required. Confirm SFP28 port compatibility and any vendor-specific compatibility lists before deployment, and handle the optical connectors by the housing to avoid contamination. For optimal performance, avoid tight bundles, maintain proper airflow around ports, and follow your equipment vendor’s installation guidance.
