BlueOptics QSFP-AOC-3M-PS-BO cable de fibra óptica InfiniBand 3 m conector macho/conector macho

The BlueOptics QSFP-AOC-3M-PS-BO is a 3-meter active optical cable (AOC) with QSFP-to-QSFP male connectors, designed for high-speed InfiniBand and multimode fibre optic links. It supports 40G transmission rates compliant with 40GBASE-SR4 and MSA QSFP AOC electrical, mechanical and functional specifications. The cable integrates optical transmitters and receivers at each end and provides a pre-assembled, plug-and-play alternative to patch cords for short-reach interconnects in racks and data centre equipment.

Advantages

This BlueOptics AOC delivers low-latency, high-bandwidth links while being immune to electromagnetic interference due to optical transmission. As an MSA-compliant QSFP solution, it offers interoperability with major network, switch and storage platforms that support QSFP AOCs. The integrated digital diagnostics (DDM/DOM) enable real-time monitoring of supply voltage, laser bias current, transmit output power, receive input power and temperature, simplifying remote troubleshooting and maintenance.

Suitable for

• High-performance computing clusters and InfiniBand fabric interconnects
• Top-of-rack and leaf-spine switch-to-switch connections
• Storage systems and SAN uplinks supporting 40G AOC interfaces
• Short-reach multimode fibre links inside data centres and server rooms

Key specifications

• Connector type: QSFP (male) to QSFP (male)
• Cable length: 3 metres (pre-assembled AOC)
• Data rate: up to 40 Gbps (40GBASE-SR4 compatible)
• Fiber type: multimode optical transmission with integrated Tx/Rx
• Digital diagnostics: DDM/DOM (MSA SFF-8472 compliant)
• MSA compliance: QSFP AOC mechanical, electrical and functional compatibility
• Shielding and EMI immunity: optical link avoids electromagnetic interference

How to use

Connect each QSFP male end to the QSFP port of the devices you wish to interconnect, ensuring the connector orientation matches the port keying. The active optical cable is plug-and-play with compatible QSFP ports; devices that support DDM/DOM can report diagnostic values through their management interfaces. No field termination or patching is required—use standard handling precautions for fibre-optic assemblies and avoid sharp bends or crushing the cable to maintain optical performance.

Recommendations

Verify that the target hardware explicitly supports QSFP AOCs and the 40GBASE-SR4 transmission protocol. Maintain bend radii according to manufacturer guidance, keep connectors clean and protected when not in use, and confirm DDM/DOM support in host equipment to enable remote diagnostics. For critical installations, test the link in your environment before large-scale deployment.
