400G QSFP-DD Active Optical Cable with DDM (1-100m): 400G-AOC-QSFP-DD

Our EDGEOPTIC 400G-AOC-QSFP-DD is a multi-vendor compatible 400G QSFP-DD active optical cable designed for ultra-high-performance 400 Gigabit Ethernet and InfiniBand HDR applications requiring extended reach beyond copper cable limitations. The 400G-AOC-QSFP-DD features point-to-point configuration with QSFP-DD connectors on both ends, utilizing embedded fiber optic technology to deliver the highest bandwidth connectivity up to 100 meters for data center interconnects, inter-row connections, and AI/ML cluster backbones in hyperscale environments.

The cable supports data rates from 212.5 to 425 Gbps, accommodating the most demanding bandwidth requirements of cutting-edge infrastructure. For Ethernet deployments, the cable handles both 200G Ethernet at 212.5 Gbps and 400G Ethernet at 425 Gbps, supporting next-generation spine-leaf architectures in cloud and hyperscale data centers. The comprehensive InfiniBand support includes EDR at 100 Gbps and HDR at 200 Gbps, making this cable essential for high-performance computing clusters, AI training infrastructure, and GPU-accelerated machine learning environments where interconnect bandwidth directly determines computational throughput.

The 400G-AOC-QSFP-DD operates at 850nm wavelength, utilizing VCSEL (Vertical-Cavity Surface-Emitting Laser) technology for transmission and PIN photodiode for receiving across eight parallel lanes. The embedded multimode fiber supports distances up to 70 meters over OM3 fiber and extends to 100 meters over OM4 fiber, providing deployment flexibility based on available infrastructure. Because the optical fibers are permanently terminated within the cable assembly, there are no exposed fiber connectors to clean or protect, dramatically simplifying installation and reducing maintenance compared to traditional optical patch cables with separate transceivers.

The cable supports host-based Forward Error Correction (FEC), enabling enhanced signal integrity and reduced bit error rates essential for mission-critical 400G applications. Active optical cables offer inherent immunity to electromagnetic interference, making them ideal for GPU cluster environments where dense compute generates significant electrical noise. The lightweight and flexible construction facilitates easier cable routing and improved airflow compared to copper alternatives.

The cable operates from a +3.3V single power supply with maximum power consumption of 8W. The electrical interface conforms to QSFP-DD MSA and CMIS V4.0 specifications, ensuring broad compatibility with standard QSFP-DD host systems from multiple equipment vendors. Our 400G QSFP-DD AOC cables can be encoded for compatibility with major networking and HPC 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. Standards compliance includes IEEE 802.3cd alongside InfiniBand EDR and HDR specifications. The cable operates within a 0 to 70°C temperature range with an MTBF rating of 1,000,000 hours.

Our 400G QSFP-DD 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-DD EEPROM memory data validation.
