BlueOptics 100G-QSFP-QSFP-AOC-3M-BO cable de fibra óptica InfiniBand 3m conector/conector

The BlueOptics 100G-QSFP-QSFP-AOC-3M-BO is a 3-metre Active Optical Cable (AOC) with QSFP28 male connectors at both ends, designed for high-speed InfiniBand and 100G Ethernet links in data centres and high-performance computing environments. The cable integrates optical transmitters and receivers and uses multimode fiber to provide a pre-assembled, low-latency connection without the need for separate transceivers or patch cords. The BlueOptics AOC conforms to QSFP28 MSA electrical and mechanical specifications and supports simultaneous send/receive operation suitable for short-reach 100GBASE-SR4 style applications.

Advantages

The cable delivers a compact, plug-and-play solution that removes the need for fibre patching and cleaning while offering immunity to electromagnetic interference. Built to MSA-compatible QSFP28 interface standards, this BlueOptics AOC supports digital diagnostics monitoring for real-time reporting of supply voltage, laser bias, transmit output power, received input power and temperature when the host hardware supports DDM/DOM. Components and assembly are aimed at high availability and long service life, with factory testing for interoperability on major hardware platforms that accept QSFP28 AOC modules.

Suitable for

• Short-reach 100G Ethernet links in data centre racks and top-of-rack switches
• InfiniBand high-performance computing interconnects requiring QSFP28 ports
• Inter-switch or switch-to-server 3 metre connections where low latency is required
• Storage systems and SAN fabrics supporting QSFP28 AOC connectivity

Key specifications

• Length: 3 metres
• Connector type: QSFP28 male to QSFP28 male
• Supported protocols: 100G Ethernet (100GBASE-SR4-style), InfiniBand and analogous high-speed optical links
• Fiber type: multimode optical fibre with integrated optical transceivers
• Digital Diagnostics Monitoring (DDM/DOM): supported when host hardware provides access
• Compliance: QSFP28 MSA compatible electrical and mechanical interface

How to use

Plug the QSFP28 connectors into the corresponding QSFP28 ports on each device, ensuring the latch engages securely and that both ends are seated fully. Check that the host devices support QSFP28 AOC modules and, if required, enable or verify DDM/DOM support in the management interface to monitor optical parameters. No separate transceivers or fibre patching is necessary; route the cable to avoid sharp bends and mechanical strain on the connectors. If the link does not come up, verify port configuration and compatibility with the device vendor’s supported module list.

Recommendations

Handle the BlueOptics AOC by the connector housings; avoid pulling on the cable jacket. Maintain bend radii above the manufacturer’s minimum to prevent increased attenuation. Confirm DDM/DOM visibility and monitor optical power and temperature metrics during commissioning and periodic maintenance. Use the 3 m length where short-reach, low-latency connections between adjacent racks or within the same rack are required.
