56G QSFP+ FDR InfiniBand Active Optical Cable (1-100m): 56G-AOC-QSFP

Our EDGEOPTIC 56G-AOC-QSFP is a multi-vendor compatible 56G QSFP+ active optical cable designed for high-performance computing, InfiniBand FDR infrastructure, and enterprise data center applications requiring extended reach beyond copper cable limitations. The 56G-AOC-QSFP features point-to-point configuration with QSFP+ connectors on both ends, utilizing embedded fiber optic technology to deliver reliable high-bandwidth connectivity up to 100 meters for HPC cluster interconnects, machine learning training infrastructure, and inter-row data center connections.

The cable supports data rates from 48 to 56.1 Gbps, optimized for InfiniBand FDR and related high-bandwidth applications. For InfiniBand deployments, the cable delivers FDR performance at 56 Gbps, providing the backbone connectivity essential for high-performance computing clusters, scientific computing environments, and GPU-accelerated machine learning infrastructure. The cable also supports 50G Ethernet at 53.125 Gbps for emerging data center applications and 16G Fiber Channel at 14.025 Gbps for storage area network connectivity in enterprise environments.

The 56G-AOC-QSFP operates at 850nm wavelength, utilizing VCSEL (Vertical-Cavity Surface-Emitting Laser) technology for transmission and PIN photodiode for receiving. The embedded multimode fiber supports distances up to 100 meters over OM3 fiber, providing significant reach advantages over copper alternatives which are typically limited to just a few meters at these data rates. Because the optical fiber is permanently terminated within the cable assembly, there are no exposed fiber connectors to clean or protect, simplifying installation and reducing maintenance requirements compared to traditional optical patch cables with separate transceivers.

Active optical cables offer inherent immunity to electromagnetic interference, making them ideal for HPC environments where servers generate significant electrical noise. The lightweight and flexible construction allows for easier cable routing in congested pathways and improved airflow compared to copper bundles, which is particularly valuable in dense compute cluster deployments where thermal management is critical.

The cable operates from a +3.3V single power supply with maximum power consumption of 1.5W. The electrical interface conforms to QSFP+ MSA and SFF-8436 specifications, ensuring broad compatibility with standard QSFP+ host systems from InfiniBand HCA vendors and switch manufacturers. Our 56G QSFP+ AOC cables can be encoded for compatibility with major HPC and enterprise equipment brands.

The cable incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality, providing real-time diagnostic data including transmitted and received optical power levels, module temperature, bias current, and supply voltage through the MSA-compatible interface. The cable operates within a 0 to 70°C temperature range with an MTBF rating of 1,000,000 hours.

Our 56G QSFP+ FDR InfiniBand active optical cable is CE/RoHS certified and compliant with product safety standards. Because our focus is providing top quality service, we perform comprehensive quality checks before delivery including optical parameter measurements, connector inspection tests, and QSFP+ EEPROM memory data validation.
