BlueOptics 100G-QSFP-QSFP-AOC-20M-BO Cabo de fibra ótica InfiniBand 20m QSFP28 macho/macho

The BlueOptics 100G-QSFP-QSFP-AOC-20M-BO is a 20-metre active optical cable (AOC) with QSFP28 male connectors on both ends, designed for high-speed InfiniBand and 100GBASE-SR4 applications. The pre-assembled multimode fibre link integrates transmitters and receivers at each end, enabling 100 Gbit/s bi-directional links between QSFP28 ports in switches, routers, servers and storage systems. The cable follows QSFP28 MSA electrical and mechanical interfaces to ensure interoperability with systems that support QSFP28 AOC modules.

Advantages

This BlueOptics AOC provides a factory-terminated, plug-and-play fibre connection that eliminates the need for separate transceivers and patch panels, reducing insertion points and potential signal loss. The integrated transceivers and multimode design reduce latency and susceptibility to electromagnetic interference compared with copper alternatives. Digital Diagnostics Monitoring (DDM/DOM) is supported to report operational parameters such as optical power and temperature when the host hardware supports these features. Components and manufacturing conform to MSA guidelines and common industrial standards, delivering stable performance and extended operational lifetime in data centre environments.

Suitable for

• High-density data centre interconnects between switches and leaf/spine fabrics
• Server-to-switch and switch-to-switch 100G links over short-reach multimode fibre
• High-bandwidth storage and compute clusters requiring low-latency links
• Environments where EMI immunity and predictable optical performance are required

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 20 metres
• Type: Active Optical Cable (AOC) with integrated Tx/Rx
• Supported data rate: up to 100 Gbit/s (100GBASE-SR4 / InfiniBand applications)
• Fibre type: multimode fibre for short-reach optical links
• Monitoring: Digital Diagnostics (DDM/DOM) support when hosted by compatible equipment
• Compliance: QSFP28 MSA mechanical/electrical interoperability and common industrial directives

How to use

Power down or follow hot-plug procedures recommended by your equipment vendor, then insert each QSFP28 connector into the corresponding QSFP28 port until it latches. Ensure ports are compatible with QSFP28 AOC modules and that firmware or host software supports the module type if DDM/DOM data is required. After insertion, verify link status on the connected devices and monitor DDM parameters if available. For removal, use the release mechanism on the connector and withdraw straight out to avoid damaging the module cage or port.

Recommendations

Route the 20 m cable to avoid sharp bends and ensure minimum bend radius is respected; maintain separation from high-heat sources and mechanical strain. Use multimode-compatible patch panels or cages if intermediate connections are necessary, and confirm that the host hardware supports QSFP28 AOCs and DDM/DOM if diagnostic access is required. Store and handle the cable by its connector bodies and keep dust caps in place when not connected.
