CBO Active Optical Cable SFP28 LinkSys SFP28-AOC-1M 1 m for 25Gb/s SFP28 ports

The CBO Active Optical Cable SFP28 LinkSys SFP28-AOC-1M 1 m for 25Gb/s SFP28 ports is a 1-metre active optical cable designed for direct, short-reach connections between devices with SFP28 interfaces. It supports 25 Gb/s line rates and provides a low-latency optical link suitable for data centre top-of-rack interconnects, server-to-switch links and high-performance NIC connections. The single-cable design eliminates the need for separate transceivers and fibres, offering a compact, power-efficient alternative to copper DACs for 25Gb/s environments.

Advantages

This active optical cable delivers consistent 25 Gb/s throughput with reduced electromagnetic interference compared with copper solutions, and its optical construction lowers heat generation in dense rack environments. The plug-and-play form factor enables straightforward installation without additional configuration. The 1-metre length is intended for short-distance interconnects inside racks or between adjacent racks, providing predictable signal integrity and low latency for latency-sensitive applications.

Suitable for

• Top-of-rack switch to server connection at 25 Gb/s
• Inter-switch short-reach links within the same rack or adjacent racks
• High-performance NIC to switch direct connections for virtualization and storage traffic

Key specifications

• Connector type: SFP28 form factor for hot-pluggable installation
• Data rate: 25 Gb/s per lane
• Cable type: Active optical cable (AOC) with integrated transceivers
• Length: 1 metre, designed for short-reach interconnects
• Latency: low-latency optical transmission suitable for time-sensitive traffic
• Power consumption: lower than equivalent copper direct-attach cables in high-density deployments
• Compatibility: designed for standard SFP28 ports on switches, servers and NICs

How to use

Insert each SFP28 connector into the SFP28 port on the corresponding devices until it latches. Ensure both devices are powered and that the ports are enabled in the device configuration if required by the host equipment. The cable is hot-pluggable; when connected properly the link status LEDs on the devices should indicate an active 25 Gb/s connection. For optimal performance avoid tight bends and do not subject the cable to excessive pulling forces.

Recommendations

Use this 1-metre AOC for short, direct links inside racks or between adjacent racks where 25 Gb/s throughput and low latency are required. Maintain bend radius specifications provided by the manufacturer and keep the environment free of excessive heat to preserve optical performance and longevity.
