In today’s digital era, data centers, telecom networks, and cloud platforms face an ever-growing demand for higher bandwidth and faster connectivity. The 400G QSFP-DD LR4 10km optical module is emerging as a key solution to meet these demands, enabling long-distance, ultra-high-speed data transmission without compromising reliability.
The QSFP-DD LR4 module supports 400 Gigabit Ethernet over single-mode fiber with a transmission distance of up to 10 kilometers. Its advanced CWDM4 technology allows four wavelengths to carry 100Gbps each, achieving a total of 400Gbps throughput. This ensures networks can handle large volumes of data while maintaining low latency and minimal signal loss.
The compact QSFP-DD form factor offers double density compared to traditional QSFP modules, making it perfect for modern high-density racks in data centers. Its hot-swappable design also ensures minimal disruption during upgrades or maintenance.
The 400G QSFP-DD LR4 is not just a component—it’s a foundation for next-generation networks. It is widely applied in:
Data Center Interconnects (DCI): Providing high-capacity, reliable links between data centers.
Metro Networks: Offering long-distance connectivity within city-scale infrastructure.
Cloud Computing Platforms: Supporting AI, big data, and multi-tenant workloads efficiently.
Enterprise Networks: Enabling scalable and future-ready communication for global operations.
Its robust design ensures consistent performance across varied network environments, making it suitable for enterprises, telecom providers, and cloud service operators alike.
Adopting 400G QSFP-DD LR4 modules brings multiple benefits. High-speed transmission allows for efficient handling of growing network traffic. Low power consumption makes it ideal for dense server racks and data centers aiming to reduce operational costs. Real-time diagnostics provide immediate feedback on temperature, voltage, and optical power, ensuring reliable and predictable performance.
Furthermore, standards compliance guarantees interoperability with existing infrastructure, allowing seamless integration and gradual network upgrades.
As 5G, cloud computing, and AI applications continue to expand, network demands are rapidly increasing. The 400G QSFP-DD LR4 ensures that networks are ready to support these bandwidth-intensive applications, providing a cost-effective, scalable, and future-proof solution. Organizations adopting this technology today are positioning themselves for the next wave of digital growth, ensuring high performance, low latency, and reliable long-distance connectivity.
