Cable óptico activo CBO SFP28-AOC-3M, 3 m SFP28 AOC para conexiones 25GbE

The BlueOptics Active Optical Cable CBO SFP28-AOC-3M is a 3-meter SFP28 AOC developed for 25GbE short-reach connections between servers, switches and storage devices. This fixed-length plug-and-play assembly replaces transceiver-plus-fiber combinations and twinax copper for data center interconnects. The integrated optical link reduces power consumption and maintains low latency while simplifying cable management in high-density racks.

Advantages

The cable delivers a compact, fixed-length form factor that eliminates the need for separate transceivers and fiber patch cords, reducing installation complexity. Its optical design offers lower power draw than equivalent transceiver-plus-fiber solutions and avoids electromagnetic interference associated with copper links. The SFP28 interfaces support 25 Gigabit Ethernet signaling with consistent low-latency performance and reliable hot-pluggable operation.

Suitable for

• Short-reach 25GbE server-to-switch connections in data centers
• Switch-to-switch leaf-spine links within racks or between adjacent racks
• Storage array uplinks and high-speed NIC interconnects
• Low-latency links for virtualized environments and high-performance computing clusters

Key specifications

• Interface: SFP28 on both ends for direct module-to-module connection
• Rated data rate: 25 Gigabit Ethernet
• Length: 3 meters fixed optical assembly
• Cable type: Active optical cable with integrated transceiver electronics
• Latency: optimized for low-latency short-reach use
• Power: lower power consumption compared with separate transceiver plus fiber assemblies
• Form factor: hot-pluggable SFP28 modules with compact housings

How to use

Insert each SFP28 connector into the corresponding SFP28 port on your network devices until the module clicks into place. Ensure both devices are powered and that ports are configured for 25GbE operation if required by the switch or NIC. No additional transceivers or fiber patch cords are needed; the fixed 3 m cable provides a direct optical link. For link validation, check device link LEDs and interface status via management software or CLI.

Recommendations

Install the cable in a managed routing path to avoid sharp bends; maintain the manufacturer’s minimum bend radius to preserve optical performance. Use the AOC for short-reach connections within the same rack or adjacent racks, and verify switch and NIC firmware compatibility with SFP28 AOCs when deploying at scale.
