InfiniBand/fibre optic cable BlueOptics 10316-BO 20 m QSFP Male/Male

The BlueOptics 10316-BO is a 20 m InfiniBand/fibre optic active optical cable (AOC) with QSFP male connectors on both ends. Designed for high-speed short-reach interconnects, this QSFP-to-QSFP cable follows MSA-compatible 40GBASE-SR4 conventions and provides an optical link over multi-mode fiber for up to 20 meters. It is intended for use in networking equipment that accepts QSFP-based 40G optical AOCs and supports point-to-point connections between switches, routers, storage systems and compatible server adapters.

Advantages

The cable transmits optical signals in both directions using built-in transmitter and receiver modules at each end and supports 40G protocols such as Ethernet and Fibre Channel over Ethernet where the host hardware accepts 40GBASE-SR4 AOCs. As an active optical cable, it avoids electromagnetic interference typical of copper links, offers reduced weight and easier routing compared with separate transceivers and patch cords, and includes digital diagnostics monitoring (DDM/DOM) support for real-time parameters like supply voltage, laser bias current, optical output and input power, and temperature when the host hardware exposes those diagnostics.

Suitable for

• Short-reach 40G interconnects in data centers and server rooms
• Direct QSFP-to-QSFP links between switches and routers
• Connecting storage systems and high-performance compute nodes
• Environments requiring immunity to electromagnetic interference

Key specifications

• Cable type: Active optical cable (AOC) with multi-mode fiber
• Connector type: QSFP male to QSFP male
• Supported nominal data rate: 40 Gbit/s (40GBASE-SR4 applications)
• Length: 20 meters
• Diagnostic interface: Digital Diagnostics Monitoring (DDM/DOM) compliant with common MSA standards
• Designed for short-reach, multi-mode fiber transmission

How to use

Install the BlueOptics 10316-BO by inserting each QSFP male connector into the corresponding QSFP port on compatible network devices while both ends are powered off or according to the equipment vendor’s hot-plug guidance. Verify that the host devices support 40GBASE-SR4 AOCs and, if needed, enable or check DDM/DOM access in the device management interface to monitor optical parameters. Route the cable to avoid sharp bends and mechanical stress and secure slack to maintain stable optical performance.

Recommendations

To ensure reliable operation, confirm host compatibility with QSFP 40G AOCs before deployment, avoid bending the cable tighter than the manufacturer’s minimum bend radius, and use the device management tools to monitor DDM/DOM values during commissioning and troubleshooting.
