Active Optical Cable CBO SFP28-AOC-3M 3 m SFP28 DAC for 25Gbps connections

CBO SFP28-AOC-3M is a 3-meter active optical cable with SFP28 connectors engineered for 25Gbps links. The cable provides a direct fiber connection between devices equipped with SFP28 ports, offering low latency and energy-efficient data transmission for short-reach environments. It is intended for use where reliable 25Gbps interconnects are required between switches, servers, or network adapters in data center and enterprise network topologies.

Advantages

The Active Optical Cable reduces power consumption compared with some traditional copper direct-attach alternatives while maintaining signal integrity over a 3 m distance. Its SFP28 form-factor connectors ensure compatibility with standard SFP28 ports and support the full 25Gbps data rate. The optical construction minimizes electromagnetic interference and provides stable performance in dense rack and cable environments.

Suitable for

• Interconnecting top-of-rack switches and aggregation switches at 25Gbps
• Direct links between servers and storage or network adapters requiring 25Gbps
• Short-reach fiber connections in data centers and telecom rooms
• High-performance networking environments needing low-latency links

Key specifications

• Connector type: SFP28 on both ends
• Data rate: 25 Gbps per link
• Length: 3 meters
• Cable type: Active optical cable (AOC)
• Latency: low, suitable for latency-sensitive applications
• EMI immunity: optical transmission reduces electromagnetic interference
• Typical use: short-reach, intra-rack or adjacent-rack connections

How to use

Ensure both devices have SFP28 ports and are configured to support 25Gbps links. Insert one SFP28 connector into each device's SFP28 slot until the latch engages. Verify link status on both devices and confirm the negotiated speed and link integrity via device interfaces or management software. If necessary, check firmware and driver compatibility on switches, servers, or adapters to ensure proper recognition of the active optical cable.

Recommendations

Route the cable to avoid sharp bends and excessive compression; maintain the manufacturer’s minimum bend radius. Use the 3 m length for short-reach connections inside racks or between adjacent racks. Verify compatibility with the host equipment and update device software when required to guarantee stable operation at 25Gbps.
