Active Optical Cable CBO SFP28-AOC-50M for 25Gbps SFP28 ports, 50 m, for SonicWall

CBO SFP28-AOC-50M is a 50-meter active optical cable designed for use with 25Gbps SFP28 ports and is compatible with SonicWall equipment. The cable provides a single-assembly connection for high-speed, low-latency links between networking devices such as switches, routers and firewalls. By replacing longer copper links with an optical assembly, it reduces susceptibility to electromagnetic interference and supports stable data centre interconnect and rack-to-rack connections at a 50 m reach.

Advantages

The active optical design delivers consistent 25Gbps performance with lower power consumption compared to some legacy electrical alternatives. Its fixed twin-ax assembly simplifies installation by providing a ready-made plug-and-play cable, eliminating the need to terminate or align separate transceivers. Optical transmission reduces signal degradation and crosstalk over the 50 m span, and the cable’s form factor is suitable for dense rack environments where space and airflow considerations matter.

Suitable for

• Data centre top-of-rack and spine-to-leaf interconnects
• Rack-to-rack links in enterprise and colocation environments
• High-performance firewall and router uplinks using 25Gbps SFP28 ports
• Environments requiring reduced electromagnetic interference compared with copper cabling

Key specifications

• Nominal data rate: 25 Gbps per lane
• Cable type: active optical cable with fixed connectors
• Physical length: 50 metres
• Connector interface: SFP28-compatible plug ends for 25Gbps ports
• Transmission medium: optical fibre within a twin-assembly cable
• Typical use case: short-reach interconnects inside racks and between adjacent racks

How to use

Install the cable by inserting each SFP28-compatible plug into the corresponding 25Gbps SFP28 port on your networking devices until the connector latches. Ensure both devices are powered down or follow hot-swap procedures recommended by the device vendor if supported. After connection, verify link status and speed through the device management interface. Route the cable to avoid sharp bends and mechanical strain; maintain recommended bend radius to preserve optical performance.

Usage recommendations

For reliable operation, use the cable within its specified 50 m reach and avoid running it alongside strong electromagnetic sources. When deploying in dense rack environments, secure and label both ends to simplify maintenance. If the connected equipment supports vendor-specific DOM or diagnostics, monitor link health periodically and follow SonicWall and BlueOptics guidance for port configuration and firmware compatibility.
