BlueOptics QSFP-AOC-3M-QL-BO InfiniBand fibre optic cable 3m Male/Male

The BlueOptics QSFP-AOC-3M-QL-BO InfiniBand fibre optic cable 3m Male/Male is a 3-metre active optical cable with QSFP form-factor connectors at both ends. It is intended for high-bandwidth, short-reach links in data center and networking racks, providing reliable, low-latency connectivity between switches, adapters and servers. The cable supports InfiniBand signaling over an optical link, combining the electrical QSFP interface with the benefits of fibre for reduced crosstalk and improved thermal performance.

Advantages

This male-to-male QSFP active optical cable delivers consistent high-speed data transfer with minimal signal degradation over a 3 m reach. The optical construction reduces electromagnetic interference and heat generation compared with direct-attach copper, while the QSFP connector ensures compatibility with systems that accept QSFP transceivers or QSFP ports. The compact, integrated cable assembly simplifies installation and eliminates the need for separate transceivers and patch cords for short interconnects.

Suitable for

• Short-reach, high-bandwidth links in data center racks
• Interconnects between InfiniBand switches, host adapters and servers
• High-performance computing (HPC) clusters requiring low latency
• Network equipment setups where QSFP ports are available for direct connection

Key specifications

• Cable length: 3 metres
• Connector type: QSFP (male) on both ends
• Transmission medium: active optical cable (AOC)
• Link type: InfiniBand-compatible high-speed data link
• Use case: short-reach interconnect for data center environments

How to use

Insert each QSFP connector into the corresponding QSFP port on the devices to be connected, ensuring alignment of the connector latch and port. No separate SFP/QSFP transceivers or patch panels are required for a direct connection; the integrated AOC handles optical transmission internally. Verify device port compatibility and link negotiation settings on connected equipment, then confirm link status and performance through the host or switch management interface.

Recommendations

Route the cable with gentle bends and avoid sharp kinks; maintain the manufacturer’s minimum bend radius for optical assemblies. Use the QSFP-AOC-3M-QL-BO in rack environments for short interconnects and avoid extended outdoor or harsh-environment exposure. Before deployment, confirm that connected devices support InfiniBand signaling over QSFP AOCs and update firmware if necessary to ensure compatibility.
