Ethiopia AOC Active Optical Cable QSFP-DD

QSFP-DD Active Optical Cables (AOCs) provide high-speed, low-latency optical connectivity for data centers and high-performance networks, supporting 200G to 400G aggregate bandwidth over multimode fiber.OverviewQSFP-DD AOCs are high-performance optical interconnects designed for short-reach applications in data centers, enterprise networks, and high-performance computing environments. They integrate multiple transmit and receive channels, enabling high aggregate bandwidth while maintaining low power consumption and signal integrity . These cables are ideal for dense top-of-rack, spine, and server interconnects where port density, airflow, and reliability are critical.Key SpecificationsData Rates: 200G (Amphenol) and 400G (Lumentum, FS, NADDOD) aggregate bandwidth .Modulation: 25Gb/s NRZ for 200G AOCs; 53.125Gb/s PAM4 for 400G AOCs .Channels: 8 transmit and 8 receive channels for 400G; 8 lanes for 200G .Cable Lengths: Typically 0.5m to 100m, customizable up to 150m depending on manufacturer .Fiber Type: Parallel multimode fiber (OM4) for short-reach links .Power Consumption: Low, e.g., 8W per end for 400G Lumentum AOCs .Standards Compliance: QSFP-DD MSA, IEEE 802.3cd, CEI-56G-VSR, OIF-CEI-04.0, QSFP-DD-CMIS-rev4p0 .AdvantagesHigh Port Density: QSFP-DD doubles the port density compared to QSFP28 AOCs, supporting more connections in the same rack space .Plug-and-Play: Designed for easy installation without complex configuration .Signal Integrity: Integrated DSP and VCSEL technology ensure low-latency, high-quality signal transmission .Compatibility: Works with major networking brands including Cisco, Arista, Dell, NVIDIA/Mellanox, Juniper, Huawei, Brocade, and Intel .Cost-Effective: Offers long-distance signal transmission with low power consumption and strong anti-interference performance .ApplicationsData Centers: High-speed interconnects between servers, switches, and storage units.High-Performance Computing (HPC): InfiniBand and Ethernet links for supercomputers.Enterprise Networks: Dense top-of-rack and spine connections requiring low latency and high reliability.Cloud Infrastructure: Short-reach optical links for hyperscale deployments . QSFP-DD AOCs are a reliable, scalable, and energy-efficient solution for modern networking needs, providing flexibility for both 200G and 400G deployments while supporting long-term growth in high-capacity networks .
