AOC cable CBO SFP28-AOC-3M 3 m passive for SFP28 ports

The BlueOptics AOC CBO SFP28-AOC-3M is a 3-meter passive active optical cable designed for SFP28 ports. It provides a direct optical link for devices that support 25Gb/s SFP28 interfaces, enabling low-latency, high-bandwidth connections between servers, switches and storage systems in data centre racks and short-reach network environments. The compact, fixed-length design reduces cable clutter and simplifies cabling routes while maintaining signal integrity for short interconnects.

Advantages

This AOC cable offers native compatibility with SFP28 ports and supports 25Gb/s data rates with low insertion loss and minimal latency compared to electrical copper alternatives. The 3 m length suits typical rack-to-rack or server-to-switch connections, and the optical medium removes concerns about electromagnetic interference. Its passive design reduces power consumption at the transceiver end and the integrated connectors simplify deployment without requiring separate transceivers or patch panels.

Suitable for

• Server-to-switch connections within the same rack or adjacent racks
• High-speed short-reach links in data centre topologies
• Storage area network interconnects requiring 25Gb/s throughput
• Clean, space-saving cabling in dense rack environments

Key specifications

• Interface type: SFP28 (25Gb/s)
• Cable length: 3 meters
• Optical medium: multimode active optical cable (AOC) technology
• Link type: fixed, direct attach optical link
• Latency: low, suitable for latency-sensitive applications
• EMI immunity: immune to electromagnetic interference due to optical transmission

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the network devices until the latch engages. Ensure both ends are seated securely and that connected devices are powered and configured for 25Gb/s operation. No additional transceivers or patch cords are required. Verify link status and speed from the device management interface and route the cable neatly within the rack to avoid excessive bending or mechanical stress.

Recommendations

For reliable performance, avoid tight bends and maintain the minimum bend radius recommended for AOC assemblies. Use this 3 m passive AOC for short-reach connections inside racks or between adjacent racks; for longer distances, consider suitable optical transceiver and fibre patch solutions. Confirm device compatibility with SFP28 optical modules and check port firmware policies if vendor lock or DAC/AOC restriction may apply.
