InfiniBand/fibre optic cable BlueOptics QSFP-H40G-AOC20M-AT-BO 20 m Male/Male

The BlueOptics QSFP-H40G-AOC20M-AT-BO is a 20 m Active Optical Cable (AOC) with QSFP-to-QSFP male connectors designed for high-speed InfiniBand and fibre optic links in data centre and enterprise network environments. It supports 40G transmission using a 40GBASE-SR4 compatible interface and integrates transmitter and receiver electronics at each end, enabling a pre-terminated, plug-and-play optical connection without the need for separate transceivers or patching.

Advantages

This 20 m BlueOptics AOC provides a reliable, low-latency optical connection that is not susceptible to electromagnetic interference, offering stable throughput for short-range high-bandwidth links. The cable is manufactured to MSA-compliant QSFP AOC specifications and is tested for compatibility with major hardware platforms that support the corresponding 40G AOC interface. Built-in digital diagnostics (DDM/DOM) enable real-time monitoring of operating parameters where supported by the host device.

Suitable for

• Data centre server-to-switch and switch-to-switch uplinks
• High-performance computing and InfiniBand clusters
• Storage system interconnects requiring 40G links
• Short-reach optical connections in enterprise networking racks

Key specifications

• Connector type: QSFP male to QSFP male
• Length: 20 metres
• Data rate: up to 40 Gbps (40GBASE-SR4 compatible)
• Cable type: Active Optical Cable (AOC) with integrated transceivers
• Optical medium: multimode fibre (integrated within AOC)
• Digital diagnostics: DDM/DOM support where host hardware permits
• Compliance: QSFP AOC Multi-Source Agreement (MSA) mechanical/electrical compatibility

How to use

Install the BlueOptics QSFP-H40G-AOC20M-AT-BO by inserting each QSFP connector into the corresponding QSFP port on your devices until the latch engages. Ensure both connected devices support 40G QSFP AOC modules and, if you intend to use digital diagnostics, verify that the host hardware or operating system can access DDM/DOM parameters. Avoid bending the cable sharply; route it within rack and chassis pathways to prevent stress on the connectors and fibre. Power and link negotiation are handled automatically by the connected network equipment once the cable is seated.

Recommendations

Use this AOC for short-range 40G links inside racks or across adjacent racks; confirm host compatibility with QSFP AOC modules and enable monitoring functions if required. Store and handle the cable in clean conditions to protect connector interfaces and prolong operational lifetime.
