Overseas Warehouse QSFP Optical Module QSFP-DD

QSFP-DD active optical modules (AOMs) provide high-speed, high-density interconnects for data centers, supporting 200G to 800G links with backward compatibility and MSA compliance.

Overview of QSFP-DD Active Optical Modules

QSFP-DD (Quad Small Form-Factor Pluggable Double-Density) modules double the lane density compared to QSFP28, supporting 8 lanes with speeds up to 28 Gbps NRZ or 56 Gbps PAM4, enabling aggregate data rates from 200G to 800G depending on the module and modulation type . These modules are designed for high-performance computing, AI/ML workloads, and data center interconnects, offering improved thermal management and flexibility in system design . Active optical cables (AOCs) in QSFP-DD form factor, such as the 200G QSFP-DD AOC, provide up to 200Gb/s aggregate bandwidth over parallel multimode fiber with reach up to 100 meters, making them ideal for intra-rack and adjacent-rack connections . They are QSFP-DD MSA compliant and backward compatible with QSFP+, QSFP28, and QSFP56 modules, allowing seamless network upgrades without replacing existing infrastructure .

Key Features

• Lane Density: 8 lanes per module, doubling port density compared to 100G QSFP28 AOCs .
• Modulation: Supports NRZ and PAM4 for high-speed data transmission .
• Reach: Typically up to 100 meters over OM3 multimode fiber for 200G AOCs .
• Backward Compatibility: Works with existing QSFP modules, enabling gradual network upgrades .
• Thermal Management: QSFP-DD ports include flexible heatsink options to optimize airflow and cooling efficiency .
• Compliance: Meets QSFP-DD MSA V5.0 and CMIS V4.0 standards, ensuring interoperability .

Overseas Warehouse and Sourcing Considerations

Many suppliers, including FS, Amphenol, TE Connectivity, and Cisco, offer QSFP-DD AOCs through overseas warehouses, enabling faster delivery and local support for international customers . These warehouses typically provide:

• Pre-tested, high-performance modules with lifetime warranties .
• ISO/IEC 27001 certified handling for secure and reliable logistics .
• Quick deployment for data center upgrades without waiting for long shipping times .

Applications

QSFP-DD AOCs are widely used in:

• Data center interconnects for 200G, 400G, and 800G networks.
• High-performance computing clusters requiring low-latency, high-bandwidth links.
• AI/ML workloads where dense, high-speed connections are critical.
• Telecommunication networks needing backward-compatible, high-density optical solutions .

Conclusion

QSFP-DD active optical modules provide a high-speed, high-density, and flexible solution for modern data centers. With overseas warehouse availability, users can access pre-certified, MSA-compliant modules quickly, supporting rapid deployment and network scalability while maintaining backward compatibility with existing QSFP infrastructure .
