Stocked optical modules QSFP-DD

QSFP-DD Active Optical Modules (AOMs) are available for 400G Ethernet, offering high-speed, long-distance fiber connectivity with advanced diagnostics and multi-vendor compatibility.OverviewQSFP-DD (Quad Small Form-Factor Pluggable Double Density) modules are designed for 400G and 800G Ethernet networks, doubling the electrical interfaces of standard QSFP modules to achieve ultra-high-speed data transmission. They are widely used in data centers, enterprise networks, and high-performance computing environments where low latency, high bandwidth, and long-distance connectivity are critical .Key FeaturesHigh-Speed Connectivity: Supports 400G Ethernet over single-mode or multi-mode fiber, with some modules capable of distances up to 500 meters (e.g., 400GBASE-DR4) using parallel single-mode fiber .Digital Diagnostics: Many modules, such as MikroTik 400G QSFP-DD, include real-time monitoring of optical power, voltage, temperature, and laser bias current, enabling proactive maintenance and performance optimization .Compatibility: QSFP-DD modules are compliant with QSFP-DD MSA, IEEE 802.3bs, and 400GAUI-8 standards, ensuring interoperability with various switches and NICs. Some modules support 4x100G breakout for flexible network scaling .Low Latency and Power Efficiency: Active optical modules consume less power than equivalent DAC solutions for long-distance connections, making them suitable for high-density deployments .Security and Advanced Features: Certain modules, like Smartoptics QSFP-DD, offer AES-256 encryption and OTN compliance for secure and multi-vendor network integration .ApplicationsData Center Interconnects: Connecting leaf and spine switches at 400G speeds.High-Performance Computing: Rack-to-rack optical links for AI/ML workloads.Enterprise Networks: Upgrading existing 100G infrastructure to 400G without replacing all hardware.Metro and Regional Networks: Coherent DWDM QSFP-DD modules support amplified networks and ROADM architectures .Availability and SuppliersMikroTik 400G QSFP-DD: Available from NAS STORE and Getic, supporting distances up to 100 meters with multi-mode fiber and advanced diagnostics .FS 400GBASE-DR4 QSFP-DD: Supports up to 500 meters over single-mode fiber, fully certified for international safety and quality standards, and compatible with multiple switch brands .Smartoptics QSFP-DD: Offers 400G and 800G options, optimized for metro, regional, and data center networks with flexible deployment options .Amphenol QSFP-DD LPO: Designed for low-latency, high-bandwidth PCIe Gen 5.0 optical links, ideal for AI/ML and rack-scale data centers . These modules are generally in stock at European and global distributors, with delivery options across the EU and worldwide. Buyers should verify compatibility with their network equipment and consider distance, fiber type, and breakout requirements when selecting a module.
