40G QSFP+ Active Optical Cable with DDM (1-100m): 40G-AOC-QSFP

Our EDGEOPTIC 40G-AOC-QSFP is a multi-vendor compatible 40G QSFP+ active optical cable designed for high-performance 40 Gigabit Ethernet, Fiber Channel, and InfiniBand applications requiring extended reach beyond copper cable limitations. The 40G-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 data center interconnects, campus backbones, and inter-building connections.

The cable supports multi-rate operation from 2.125 to 41.2 Gbps, accommodating various network protocols and applications. For Ethernet deployments, the cable handles both 10G Ethernet at 10.31 Gbps and 40G Ethernet at 41.25 Gbps, providing flexibility for mixed-speed network environments. Fiber Channel support includes 2G FC at 2.125 Gbps, 4G FC at 4.25 Gbps, 8G FC at 8.5 Gbps, and 10G FC at 10.52 Gbps, making the cable well-suited for storage area network connectivity. Additionally, the cable supports InfiniBand applications including SDR at 10 Gbps, DDR at 20 Gbps, and QDR at 40 Gbps for high-performance computing cluster interconnects.

The 40G-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. Because the optical fiber is permanently terminated within the cable assembly, there are no exposed fiber connectors to clean or protect, simplifying installation and maintenance compared to traditional optical patch cables with separate transceivers.

Active optical cables offer inherent immunity to electromagnetic interference, making them ideal for environments with significant electrical noise such as adjacent to power distribution units, motor drives, or industrial equipment. The lightweight and flexible construction allows for easier cable routing in congested pathways and improved airflow compared to bulky copper bundles, which is particularly valuable in high-density data center deployments.

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 multiple equipment vendors. Our 40G QSFP+ AOC cables can be encoded for compatibility with over 80 different 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. Standards compliance includes IEEE 802.3ba for 40 Gigabit Ethernet alongside QDR InfiniBand specifications. The cable operates within a 0 to 70°C temperature range with an MTBF rating of 1,000,000 hours.

Our 40G QSFP+ 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.
