Aktívny optický kábel CBO SFP28-AOC-7M 7 m SFP28 twinax-kompatibilný, 25 Gbit/s

Active Optical Cable CBO SFP28-AOC-7M is a 7 m SFP28-compatible fiber cable engineered for 25 Gbps links between switches, servers and other network devices. The cable uses an SFP28 form-factor on both ends to provide a plug-and-play optical connection for short-reach, high-speed interconnects. Its optical design reduces electromagnetic interference and cabling bulk compared with copper twinax, while supporting low-latency data transmission suitable for data center and enterprise top-of-rack and leaf-spine deployments.

Advantages

The Active Optical Cable offers a lightweight, flexible alternative to passive copper twinax for 25 Gbps links over a 7-meter distance. It provides a small form-factor SFP28 interface that simplifies installation and hot-plug replacement without additional transceivers. Because the link is optical, it eliminates susceptibility to electromagnetic interference and enables longer clean reach than equivalent copper solutions. The design supports low power consumption and consistent signal integrity across the full length, helping maintain predictable latency and throughput in dense cabling environments.

Suitable for

• Short-reach server-to-switch and switch-to-switch connections in data centers
• Top-of-rack and leaf-spine network architectures
• Hyperconverged and high-performance computing clusters requiring 25 Gbps links
• Environments where reduced electromagnetic interference and lower cable bulk are required

Key specifications

• Connector type: SFP28 form-factor on both ends for direct module-style insertion
• Length: 7 meters optical cable
• Nominal data rate: 25 Gbps duplex
• Transmission medium: active optical fiber (AOC)
• Typical use: short-reach high-speed interconnects between network devices
• Latency: designed for low-latency data transmission suitable for switch and server interconnects

How to use

Insert each SFP28 end into the corresponding SFP28 port on the network devices until the module latches. Ensure both devices are powered and that the ports are configured for 25 Gbps operation if manual configuration is required. The cable is plug-and-play with systems that support SFP28 AOC modules; software-level link negotiation and diagnostics are handled by the host equipment. Avoid sharp bends and maintain manufacturer-recommended bend radius along the cable run to preserve optical performance.

Recommendations

For optimal performance, route the cable to minimize stress and avoid routing near high-heat sources. Verify compatibility with the host devices' SFP28 ports and update firmware if required for SFP28 AOC support. When installing in dense racks, label both ends to simplify future maintenance and avoid excessive compression or kinks that could affect optical signal quality.
