Aktívny optický kábel CBO AOC-SFP-25G-20M-BO 20 m SFP28 25 Gbit/s

The Active Optical Cable CBO AOC-SFP-25G-20M-BO is a 20-meter SFP28 AOC engineered for 25 Gbit/s short-reach links. It connects SFP28 ports on switches, servers and storage appliances without separate transceivers, delivering high-speed, low-latency optical transmission over a single pre-terminated cable assembly. The cable provides electrical isolation and immunity to electromagnetic interference while simplifying rack-to-rack and within-rack cabling in data center and enterprise network environments.

Advantages

This active optical cable supports 25 Gbit/s line rates with SFP28 form-factor compatibility, reducing the need for standalone transceivers and associated power and heat. Its optical link over 20 meters minimizes signal loss compared with long copper assemblies at equivalent data rates and avoids issues related to electromagnetic interference. The pre-terminated design eases installation and inventory management while the low-latency optical path is suitable for latency-sensitive applications.

Suitable for

• Short-reach interconnects between top-of-rack and aggregation switches
• Server-to-switch connections in dense rack deployments
• High-performance storage and compute clusters requiring 25 Gbit/s links
• Data center environments where EMI immunity and reduced power/heat are desired

Key specifications

• Connector type: SFP28 to SFP28
• Data rate: 25 Gbit/s per pair
• Cable length: 20 meters
• Type: Active optical cable (AOC)
• Transmission medium: Multi-mode optical fibre with integrated transceivers
• Typical latency: low, suitable for latency-sensitive applications
• EMI performance: immune to electromagnetic interference

How to use

Install the Active Optical Cable by inserting each SFP28 connector into corresponding SFP28 ports on the devices to be connected. No additional transceivers or fibre termination are required. Ensure ports are powered and enabled in the host equipment; some devices may require link negotiation or port configuration to operate at 25 Gbit/s. Route the cable to avoid sharp bends and mechanical strain, securing it with cable ties or guides to maintain recommended bend radius and prevent damage to the optical assembly.

Recommendations

Verify compatibility with the host equipment’s SFP28 ports and firmware requirements before deployment. Maintain the specified bend radius and avoid crushing the cable. For best performance in data center installations, combine this 20 m AOC with proper airflow and cable management to minimize thermal impact and to sustain reliable 25 Gbit/s links.
