Active Optical Cable CBO SFP28-AOC-50M-DL-BO — 50 m SFP28 AOC for 25GbE connections

CBO SFP28-AOC-50M-DL-BO is a 50-meter active optical cable (AOC) with SFP28 connectors engineered for 25 Gigabit Ethernet interconnects between servers, switches and storage devices. The cable offers a factory-terminated, hot-pluggable solution that replaces equivalent copper direct-attach cables for short to mid-range links, delivering low latency, reduced weight and immunity to electromagnetic interference. Its pluggable SFP28 form factor is compatible with SFP28 ports on networking equipment that support 25GbE links.

Advantages

The AOC provides stable 25GbE throughput with minimal signal loss over a 50 m distance, while eliminating susceptibility to RF interference common to copper cabling. Being fully factory-terminated, it reduces installation time and the need for field termination or testing. The lightweight fiber construction reduces rack-to-rack cable bulk and improves airflow compared with comparable copper assemblies.

Suitable for

• Short to mid-range data center links between servers and top-of-rack or spine switches
• Interconnects for storage arrays and SAN fabrics requiring 25GbE bandwidth
• High-density racks where reduced cable bulk and airflow are important
• Environments sensitive to electromagnetic interference

Key specifications

• Connector type: SFP28 to SFP28
• Cable type: Active optical cable (AOC)
• Maximum supported link speed: 25 Gigabit Ethernet
• Length: 50 meters
• Latency: low, suitable for latency-sensitive applications
• Plug-and-play: factory-terminated, hot-pluggable
• EMI immunity: optical transmission reduces electromagnetic interference
• Physical characteristics: lightweight fiber assembly for reduced cable bulk

How to use

Insert each SFP28 transceiver end into compatible SFP28 ports on the devices to be linked, ensuring the connectors are firmly seated. Verify that both endpoints support 25GbE operation and that firmware or switch settings allow the link to negotiate at 25 Gbps. No additional transceivers or external power are required beyond the host ports; the cable is factory-terminated and ready for immediate use. Monitor link status via your switch or server management interface to confirm a stable connection after insertion.

Usage recommendations

Route the cable to avoid sharp bends and mechanical strain; maintain the manufacturer’s recommended minimum bend radius. Use appropriate cable management to preserve airflow and avoid obstructing fans or vents. For mixed-vendor environments, confirm host compatibility and any required configuration for SFP28 AOC modules before deployment.
