Cavo InfiniBand CBO AOC-S-S-25G-1M-BO — 25G, 1 m, cavo ottico attivo

Active optical InfiniBand cable CBO AOC-S-S-25G-1M-BO is a 1 metre Active Optical Cable (AOC) engineered for 25G data links in data centres and high-performance computing environments. The cable combines optical transmission with integrated transceivers to deliver low-latency, high-bandwidth connectivity between servers, switches and storage systems. Compared with copper alternatives, the AOC offers electrical isolation and reduced electromagnetic interference for reliable short-reach interconnects.

Advantages

This InfiniBand AOC supports 25G signalling over a short 1 m span while keeping power consumption and latency low through optical transmission. Its active optical design integrates transceiver electronics with fibre to maintain signal integrity and error performance at high data rates. The cable provides electrical isolation between connected devices, minimising ground-loop issues and improving system stability in dense rack environments. The small form factor and flexible jacket simplify routing in confined spaces.

Suitable for

• Short-reach server-to-switch or switch-to-switch links in racks and top-of-rack deployments
• High-performance computing clusters requiring low-latency 25G interconnects
• Storage arrays and SAN nodes that need reliable optical connectivity with reduced EMI
• Data centre environments where electrical isolation between devices is necessary

Key specifications

• Nominal data rate: 25 Gbps
• Length: 1 metre
• Cable type: active optical cable (AOC)
• Connector type: SFF-style low-profile optical connectors (infiniBand-compatible)
• Signal characteristics: low latency, optical transmission for EMI immunity
• Typical use: short-reach interconnects within racks and across adjacent racks

How to use

Connect each end of the AOC to compatible InfiniBand ports on servers, switches or storage devices. Ensure ports are powered down or follow hot-plug precautions recommended by the equipment manufacturer when inserting or removing the cable. Route the cable to avoid sharp bends and mechanical strain on connectors; maintain the minimum bend radius specified by the device vendor. Verify link status and negotiate 25G speeds through the host or switch management interface.

Recommendations

Inspect optical connectors for dust or debris before installation and use dust caps when the cable is not connected. For best performance, avoid running the AOC alongside high-power copper cables for extended distances. Use within data centre temperature and humidity ranges and follow vendor guidelines for hot-plugging and cable handling to preserve signal quality and device longevity.
