Aktívny optický kábel CBO SFP28 BlueOptics BO272703Q20M 20 m

Active Optical Cable CBO SFP28 BlueOptics BO272703Q20M 20 m is a factory-assembled SFP28 AOC designed for 25GbE short-range interconnects. The cable integrates SFP28 transceiver modules with a fixed optical fiber, delivering high-speed data transmission between switches, servers and storage units over a 20 meter link. The design provides electrical isolation and reduced weight compared to copper direct attach cables, while maintaining low latency and signal integrity for data centre and high-performance networking environments.

Advantages

This SFP28 AOC offers a simplified cabling solution with plug-and-play deployment and no separate transceiver to install. Optical transmission reduces susceptibility to electromagnetic interference and provides electrical isolation between connected devices. The integrated active optics enable low-latency 25GbE links over 20 metres with consistent performance and lower power dissipation than some active copper alternatives. The cable’s construction reduces rack clutter and eases airflow management in dense installations.

Suitable for

• Short-reach 25GbE connections between switches in data centres
• Server-to-switch uplinks in high-performance computing and virtualization environments
• Direct links between storage arrays and networking equipment
• Top-of-rack to aggregation switch connections within the same equipment room

Key specifications

• Interface: SFP28 on both ends for 25 Gigabit Ethernet
• Length: 20 metres optical cable
• Transmission medium: active single/multi-mode optical assembly (factory-integrated)
• Data rate: 25 Gbit/s per lane (25GbE)
• Connector style: SFP28 module housing for hot-pluggable use
• Electrical isolation: optical link provides galvanic isolation between devices
• Typical use environment: data centre and enterprise network racks

How to use

Install the AOC by inserting each SFP28 module into compatible SFP28 ports on network switches, servers or storage controllers while the equipment is powered according to vendor guidelines. The cable is plug-and-play and requires no separate transceiver configuration in most modern network operating systems. Verify link status and speed on connected devices after insertion and follow standard hot-plug handling procedures to avoid mechanical damage. For best performance, route the cable to avoid sharp bends and excessive strain on the module housings.

Recommendations

Confirm SFP28 port compatibility and supported 25GbE firmware with your hardware vendor. Maintain bend radius guidelines and avoid exposing the cable to harsh mechanical stress or fluids. Use within controlled data centre temperatures and clean rack environments to ensure longevity and consistent signal performance.
