InfiniBand Active Optical Cable CBO QSFP-AOC-2M-DL-BO 2 m QSFP+ to QSFP+

InfiniBand Active Optical Cable CBO QSFP-AOC-2M-DL-BO 2 m QSFP+ to QSFP+ is a 2‑metre Active Optical Cable (AOC) with QSFP+ connectors on both ends, intended for InfiniBand environments. The cable delivers a direct optical link between QSFP+ ports on switches, servers and storage devices, providing electrical isolation and short-range high-speed connectivity without separate transceiver modules. It is designed for data center and high-performance computing (HPC) applications where compact, low-latency interconnects and reliable throughput are required.

Advantages

This Active Optical Cable reduces rack congestion by combining optical fibre performance with the simplicity of a direct-attached cable, eliminating the need for standalone transceivers. The QSFP+ form-factor on both ends supports straightforward plug-and-play installation and ensures full compatibility with QSFP+ InfiniBand ports. As an optical solution, the cable provides electrical isolation between connected devices and supports consistent signal integrity over the specified 2 m length, making it suitable for short-reach, high-bandwidth links in dense network topologies.

Suitable for

• Short-range interconnects between QSFP+ ports on switches and servers in data centres
• High-performance computing (HPC) cluster fabric links requiring low latency
• Direct-attached storage and switch connections where compact cabling is needed
• Low-electrical-interference environments that benefit from optical isolation

How to use

Install the QSFP-AOC-2M-DL-BO by inserting each QSFP+ connector into the corresponding QSFP+ port on your network devices until the latch engages. Ensure both devices are powered down or follow hot-plug guidelines from the device manufacturers if connecting live. Verify link status via device management interfaces or LEDs to confirm negotiation and proper operation. Use cable routing that avoids excessive bending; maintain minimum bend radius recommended by the device or cable vendor to preserve optical performance.

Recommendations

Use this 2 m QSFP+ AOC for short-distance links inside racks or between adjacent racks. Avoid kinking or tightly coiling the cable, and keep connectors free from dust when not connected. Refer to your switch or server documentation for supported QSFP+ modes and link settings to ensure compatibility with InfiniBand configurations.
