BlueOptics QSFP-H40G-AOC3M-AT-BO InfiniBand fibre optic cable 3 m Male/Male

The BlueOptics QSFP-H40G-AOC3M-AT-BO InfiniBand fibre optic cable is a 3 m active optical cable (AOC) with QSFP-to-QSFP connectors engineered for high-speed, low-latency links in data center and high-performance computing environments. It supports 40GBASE-SR4 transmission over multimode fiber with integrated transceiver electronics on each end, providing a pre-terminated solution that eliminates patching and reduces connector-related attenuation. The cable is designed to comply with QSFP MSA electrical and mechanical specifications and is compatible with equipment that supports standard QSFP AOC interfaces.

Advantages

The cable provides a ready-made optical connection that reduces installation time and minimizes potential signal loss from field-terminated connectors. Built to MSA-compatible QSFP AOC standards, it integrates transmitter and receiver assemblies at both ends to deliver stable 40 Gbps links over 3 meters. Digital Diagnostics Monitoring (DDM/DOM) support enables real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature for easier maintenance and troubleshooting. The pre-assembled multimode AOC design removes the need for patch cords and frequent cleaning while meeting common industrial safety and environmental directives.

Suitable for

• Short-reach interconnects between switches and routers in racks and cabinets
• Server-to-switch and server-to-storage connections in HPC and enterprise environments
• Top-of-rack and spine network links requiring 40 Gbps bandwidth
• Environments where reduced electromagnetic interference and low latency are required

Key specifications

• Length: 3 meters
• Connector type: QSFP (QSFP to QSFP)
• Data rate: up to 40 Gbps (40GBASE-SR4)
• Optical medium: multimode fiber with integrated active transceivers
• Monitoring: Digital Diagnostics Monitoring (DDM/DOM) compliant with SFF-8472
• Form factor: pre-terminated active optical cable (AOC)
• Compliance: designed to meet QSFP MSA mechanical/electrical specifications and common industrial directives

How to use

Install the BlueOptics QSFP-H40G-AOC3M-AT-BO by plugging the QSFP connectors into compatible QSFP ports on switches, routers, servers or storage devices while the equipment is powered down or according to your hardware vendor's hot-plug guidelines. Verify that the host hardware supports QSFP AOC modules and, if desired, enable or query the DDM/DOM interface to monitor optical parameters. Because the cable is pre-assembled, no field termination, polishing or patch cord cleaning is required; ensure the QSFP port receptacles are free of dust before insertion to maintain optimal signal quality.

Usage recommendations

Use this 3 m AOC for short-reach trunking and device interconnects inside racks and between adjacent cabinets. Confirm compatibility with your hardware vendor's QSFP AOC support and use the DDM data when performing diagnostics or documenting link health. Avoid sharp bends and mechanical strain on the cable, and store unused cables in a clean, dry environment to preserve component lifetime.
