Active Optical Cable CBO SFP28-AOC-2M-QN-BO 2 m SFP28 twinax compatible for 25GbE links

CBO SFP28-AOC-2M-QN-BO is a 2 m active optical cable with SFP28 connectors designed for 25 Gigabit Ethernet links. It delivers a fixed fiber connection that lowers latency compared with longer copper assemblies and eliminates susceptibility to electromagnetic interference. The cable is intended to interconnect compatible SFP28 ports on switches, servers and storage systems, offering a compact point-to-point solution for short-reach high-speed links in data center and enterprise network environments.

Advantages

The active optical assembly combines SFP28 form-factor connectors with an optical fiber medium to provide stable 25GbE signal transmission over a 2 m reach. Its design reduces weight and bulk relative to traditional copper twinax while maintaining low power consumption at the transceiver endpoints. The optical link simplifies cable management in dense racks and minimizes crosstalk and EMI issues that can affect copper connections, supporting reliable high-speed interconnects in rack-to-rack and server-to-switch scenarios.

Suitable for

• 25 Gigabit Ethernet short-reach links between switches
• Server-to-switch direct connections in data centers
• High-speed storage system interconnects
• Dense rack environments where reduced cable bulk is required

Key specifications

• Form factor: SFP28-compatible connectors
• Nominal reach: 2 metres (fixed-length active optical cable)
• Data rate support: 25 Gbit/s physical lane for 25GbE links
• Medium: active optical fiber with integrated transceivers
• Latency: low, suitable for short-reach high-speed interconnects
• EMI performance: immune to electromagnetic interference compared with copper
• Cable design: compact, lightweight fixed assembly for point-to-point connections

How to use

Install the cable by inserting the SFP28 connectors into compatible SFP28 ports on each device until the connector latch engages. Ensure both ports support 25GbE and are enabled in the device firmware or operating system. No additional configuration is required at the physical layer beyond standard port settings; higher-layer network configuration should be performed according to the network design. Avoid sharp bends near the cable heads and maintain the recommended bend radius for optical fiber to preserve signal integrity.

Usage recommendations

For best results, verify port compatibility and firmware support on switches and servers before deployment. Route the cable to minimize mechanical stress and maintain airflow in racks. Use this active optical cable for short-distance 25GbE links where reduced EMI and compact cabling are priorities.
