Cable óptico activo CBO InfiniBand SFP28 AOC-S-S-25G-30M-BO 25G 30 m

The CBO InfiniBand SFP28 Active Optical Cable AOC-S-S-25G-30M-BO 25G 30 m is a 30-meter active optical cable equipped with SFP28 connectors for 25 Gigabit data transmission. Designed for server, switch and storage interconnects, this AOC provides an optical alternative to copper direct-attach cables, delivering low latency and high bandwidth over a 30 m reach while eliminating susceptibility to electromagnetic interference common in copper links.

Advantages

The active optical cable combines SFP28 compatibility with optical transceivers integrated into the cable ends to support 25G links with minimal signal loss and improved insertion loss characteristics compared with passive solutions. Its 30 m length enables flexible rack-to-rack and equipment-to-equipment connections in data center and HPC layouts. The optical medium reduces electrical noise and heat generation in dense deployments and simplifies cable management due to a thinner, more flexible cable profile.

Suitable for

• 25G connections between servers and top-of-rack or leaf switches
• High-performance computing (HPC) cluster interconnects requiring low latency
• Storage area network (SAN) links and access to NVMe-oF targets
• Data center rack-to-rack optical links up to 30 meters
• Environments where reduced electromagnetic interference and improved signal integrity are required

Key specifications

• Data rate: 25 Gigabit per second per lane
• Connector type: SFP28 on both ends
• Medium: active multimode optical cable with integrated transceivers
• Maximum reach: 30 meters
• Latency: low-latency optical link suitable for performance-sensitive applications
• Cable profile: thin, flexible fiber assembly for improved routing and management

How to use

Install the cable by inserting each SFP28 connector into compatible SFP28 ports on network switches, servers or storage systems until the retention latch engages. Verify link status via device LEDs or management interfaces and configure the connected equipment for 25G operation if required. Handle the cable by the connector housings, avoid tight bends that exceed the manufacturer's minimum bend radius, and secure the cable to racks or cable management paths to prevent strain on the connectors.

Recommendations

For reliable performance, use this AOC in matching SFP28-capable equipment and avoid mixing passive copper DACs and active optical links on the same port pairs without confirming compatibility. Maintain bend radius guidelines, keep connector end-faces clean, and perform routine port diagnostics after installation to ensure stable 25G links in data center and HPC environments.
