AOC cable CBO SFP28-AOC-20M 20 m length — Active Optical Cable for SFP28

The AOC cable CBO SFP28-AOC-20M is an Active Optical Cable designed for direct connection between SFP28 ports over a 20 meter optical link. It supports 25GbE data rates and is intended for high-performance interconnects between servers, switches and storage devices. The construction provides low latency data transmission, immunity to electromagnetic interference and a lightweight, flexible cable assembly suitable for densely cabled racks and equipment rooms.

Advantages

This Active Optical Cable delivers 25GbE performance with lower power consumption and reduced signal loss compared with long copper assemblies. The optical design eliminates susceptibility to EMI, offers improved signal integrity over the full 20 m length and reduces rack clutter through thinner, more flexible cabling. The integrated SFP28 connectors provide a plug-and-play interface compatible with standard SFP28 ports, simplifying installation and replacement.

Suitable for

• High-speed server-to-switch links in data centers
• Switch-to-switch stacking and aggregation connections
• Storage array interconnects requiring 25GbE bandwidth
• Environments needing EMI immunity and minimal crosstalk
• Dense cabling scenarios where flexible, space-saving cabling is preferred

Key specifications

• Interface: SFP28 to SFP28
• Link length: 20 m optical cable
• Supported data rate: 25 Gigabit Ethernet (25GbE)
• Transmission medium: multimode active optical cable
• Connector type: SFP28 form factor with integrated optical transceivers
• Latency: low-latency optical transmission suitable for enterprise networks
• Immunity: resistant to electromagnetic interference (EMI) due to optical media
• Cable design: flexible, lightweight jacket for improved routing in racks

How to use

Insert each SFP28 connector into the corresponding SFP28 port on the devices to be linked, ensuring the module latches are engaged. Verify link status LEDs on both devices and confirm the negotiated speed is 25GbE where supported. Use standard network management tools to monitor link health and traffic. Avoid sharp bends in the optical cable and secure the cable to prevent mechanical strain on the connectors.

Usage recommendations

Install the cable in environments that meet equipment manufacturer guidelines for temperature and humidity. For optimal performance, maintain a bend radius according to the cable manufacturer’s specifications and avoid routing the cable alongside high-power electrical conductors to ease maintenance and reduce mechanical stress.
