QSFP-DD Spec
Introduction:
The QSFP-DD (Quad Small Form Factor Pluggable Double Density) is a highly versatile and advanced optical transceiver module. It is designed to meet the increasing demand for higher port densities and bandwidth in data centers and telecommunications networks.
Features:
1. Increased Port Density:
The QSFP-DD module features a double-density design, allowing for up to 8 high-speed electrical lanes or up to 16 lanes of 100 Gbps optical transceivers in a single module. This significantly increases port density and allows for more efficient utilization of space in networking equipment.
2. Higher Data Rates:
The QSFP-DD supports data rates of up to 400 Gbps per port, making it suitable for high-bandwidth applications such as cloud computing, artificial intelligence, and 5G networks. With its enhanced performance, the QSFP-DD enables faster data transmission and improved network performance.
3. Enhanced Power Management:
To optimize power consumption and reduce energy costs, the QSFP-DD incorporates advanced power management features. It supports four power classes, including Class 1 (less than 3.5W), Class 2 (less than 5W), Class 3 (less than 8W), and Class 4 (up to 12W). This flexibility allows system designers to tailor power usage to meet specific requirements.
4. Multi-Die Integration:
The QSFP-DD module employs multi-die integration technology, which integrates multiple semiconductor dies into a single package. This integration enables the module to deliver higher performance, lower power consumption, and improved thermal management. It also allows for more efficient manufacturing and testing processes.
5. Backwards Compatibility:
To ensure smooth migration from existing QSFP modules, the QSFP-DD is designed to be backward compatible with QSFP and QSFP+ form factors. This compatibility enables easy integration into existing networking equipment without the need for significant infrastructure changes.
Conclusion:
The QSFP-DD specification provides a comprehensive and flexible solution for high-density and high-speed optical transceivers. With its increased port density, higher data rates, enhanced power management, multi-die integration, and backward compatibility, the QSFP-DD is well-positioned to meet the evolving demands of data centers and telecommunications networks. Its advanced features and performance make it an ideal choice for next-generation networking applications.
