Active Optical Cable CBO SFP28-AOC-20M 20 m SFP28 (Direct-attach QSFP28/SFP28 compatible)

CBO SFP28-AOC-20M is a 20-meter active optical cable with SFP28 interfaces engineered for 25 Gbps connections between compatible SFP28 ports. The cable creates a low-power, low-latency optical link suitable for top-of-rack switches, servers and storage systems in data centers and telecommunications equipment. It replaces equivalent copper direct-attach assemblies where optical transmission is preferred for improved noise immunity and tidier cabling across short to medium reaches.

Advantages

The Active Optical Cable offers stable 25 Gbps throughput with reduced electromagnetic interference and lower heat dissipation compared with copper alternatives. Its integrated SFP28 transceivers eliminate the need for separate modules, simplifying installation and inventory management. At 20 meters length the cable supports flexible rack-to-rack or intra-row interconnects while maintaining low latency and modest power consumption typical of AOC solutions.

Suitable for

• Top-of-rack and leaf-spine switch connections
• Server-to-switch high-speed links
• Storage array interconnects and SAN fabric links
• Telecommunications equipment cabinets and patching in data halls

Key specifications

• Interface type: SFP28 on both ends for 25 Gbps operation
• Length: 20 meters optical cable
• Transmission rate: up to 25 Gbit/s per lane
• Form factor: active optical cable with integrated transceivers
• Latency: low-latency optical signal suitable for switch and server interconnects
• Power consumption: typical AOC-class low power draw compared with active copper equivalents

How to use

Install the CBO SFP28-AOC-20M by inserting each SFP28 connector into the corresponding SFP28 port on your network devices until the latch engages. Ensure both ends seat fully and that devices are powered according to manufacturer guidance. Verify link status via the switch or server management interface and confirm negotiated speed at 25 Gbps. For hot-plug operations, follow your equipment’s safe insertion and removal procedures to avoid port damage.

Recommendations

Use the cable in indoor data center or telecommunications environments free from excessive moisture, direct sunlight or mechanical strain. Avoid sharp bends and secure the cable to prevent tension at connector ends. When replacing copper direct-attach assemblies, confirm compatibility of SFP28 ports and firmware support for AOC modules in your hardware.
