Active Optical Cable CBO SFP28 Radware SFP28-AOC-20M — 20 m SFP28 direct-attach AOC

Active Optical Cable CBO SFP28 Radware SFP28-AOC-20M — 20 m SFP28 direct-attach AOC is a 20‑meter SFP28 direct-attach active optical cable engineered for 25GbE/25G links between devices with SFP28 ports. The cable delivers an optical connection with low latency and reduced electromagnetic interference, suitable for data center topologies where rack-to-rack or row-to-row connectivity is required. Its direct-attach form factor simplifies installation compared with separate transceiver and patch cable combinations and supports high-density deployments.

Advantages

The SFP28 direct-attach AOC offers a lightweight and compact solution for 25GbE connectivity, providing consistent signal integrity over a 20 m distance while minimizing cable bulk in dense server and switch environments. Because it is an active optical cable, it reduces susceptibility to electrical interference and delivers lower power dissipation compared with some electrical cable alternatives. The integrated design eliminates the need for separate transceivers and fiber patch cords, simplifying inventory management and reducing insertion points that could affect link reliability.

Suitable for

• 25GbE interconnects between switches and top-of-rack or leaf switches
• Server uplinks and high-speed links within data center racks
• Aggregation layer connections requiring compact, low-latency cabling
• Environments where electromagnetic interference should be minimized

Key specifications

• Connector type: SFP28 direct-attach active optical cable
• Supported data rate: 25 Gbps per lane (25GbE)
• Cable length: 20 meters
• Signal type: optical with active electronics
• Form factor: hot-pluggable SFP28 modules at both ends
• Typical use: rack-to-rack and row-to-row data center interconnects

How to use

Install the cable by inserting each SFP28 module into the corresponding SFP28 port on the network devices until the latch engages. Ensure both devices are powered down or that the network supports hot-plug operations according to the device vendor guidelines. Verify link status through the switch or server management interface and confirm 25GbE negotiation where applicable. Route the cable to avoid sharp bends and secure it to prevent strain on the connector ends. For replacement, remove the cable by releasing the latch and pulling the module straight out to avoid damaging the port.

Usage recommendations

Use the AOC in typical data center ambient conditions and follow vendor recommendations for bend radius and handling. Confirm compatibility with your switch and server vendor for SFP28 AOC support and firmware requirements. For optimal performance, avoid running the cable alongside high-power electrical cabling and maintain proper airflow around networking equipment.
