InfiniBand/fibre optic cable BlueOptics QSFP-H40G-AOC2M-AT-BO 2 m Male/Male

The BlueOptics QSFP-H40G-AOC2M-AT-BO is a 2 m active optical cable (AOC) with QSFP-to-QSFP connectors designed for 40G data transmission over multimode fiber. The cable follows MSA-compliant QSFP AOC standards and integrates a transmitter and receiver on each end to support high-speed protocols such as 40GBASE-SR4, Ethernet and Fibre Channel over Ethernet. The 2 m length and male-to-male QSFP configuration make it suitable for direct connections between switches, routers, storage systems and other compatible networking hardware that accept QSFP AOCs.

Advantages

This BlueOptics AOC provides a pre-assembled fiber solution that eliminates the need for patch cords and manual connector cleaning, reducing insertion loss and simplifying installation. Components are selected to meet industry MSA standards and the cable supports Digital Diagnostics Monitoring (DDM/DOM) for real-time information on supply voltage, laser bias current, output and received optical power, and temperature when supported by the host hardware. The active design enables reliable 40 Gbit/s links over 2 m with immunity to electromagnetic interference.

Suitable for

• Short-reach 40G connections in data center switch-to-switch links
• Direct QSFP connections between routers, SAN switches and storage arrays
• High-bandwidth aggregation and uplink ports in network racks
• Environments requiring reduced latency and EMI-immunity

Key specifications

• Connector type: QSFP (QSFP to QSFP), male/male
• Transmission mode: Active Optical Cable (AOC) over multimode fiber
• Nominal data rate: 40 Gbit/s (supports 40GBASE-SR4 and equivalent protocols)
• Length: 2 meters
• Digital diagnostics: DDM/DOM support for real-time monitoring (if supported by host)
• Compliance: QSFP AOC MSA compliant; meets common industrial regulations (CE, RoHS, FCC where applicable)
• Typical lifetime: designed for long operational life and high MTBF

How to use

Ensure both devices have QSFP ports that support QSFP AOCs and, if you require diagnostics, that the host hardware supports DDM/DOM. With power to the devices turned off or ports administratively disabled, align and insert each QSFP plug into the corresponding QSFP slot until the latch engages. Enable the ports in your device management interface and verify link status. Use the host management tools to read DDM/DOM parameters when available. To avoid damage, handle the cable by the connector housings and avoid sharp bends beyond the manufacturer's minimum bend radius.
