Unmatched Technical Specifications

The 400GBase-QSFP-DD LR4 10km optical module is engineered to deliver top-tier performance. Operating at a data rate of 400Gbps, it ensures that large volumes of data are transmitted swiftly, making it ideal for bandwidth-intensive applications. The module supports a transmission distance of up to 10km over single-mode fiber (SMF), providing the flexibility needed for medium to long-range network connections.


One of its key features is the QSFP-DD (Quad Small Form-Factor Pluggable Double Density) form factor. This compact design not only saves space in network equipment but also allows for higher port density, enabling network operators to maximize the utilization of their hardware. The LR4 specification ensures that the module operates with four lanes of 100Gbps each, using wavelength-division multiplexing (WDM) technology to transmit data over a single fiber, optimizing fiber usage and reducing infrastructure costs.


Reliable Performance and Robust Design

Reliability is a cornerstone of the 400GBase-QSFP-DD LR4 10km module. It is built to withstand the rigors of continuous operation in various environments. The module operates within a wide temperature range, ensuring stable performance even in harsh conditions. Whether deployed in data centers, telecommunications networks, or enterprise environments, it consistently delivers low latency and high signal integrity, minimizing data loss and ensuring smooth network operations.


Moreover, the module adheres to strict industry standards, ensuring compatibility with a wide range of network equipment from leading manufacturers. This interoperability simplifies integration into existing networks, reducing the complexity and cost of upgrades. Each module undergoes rigorous testing and quality control procedures to guarantee that it meets or exceeds performance specifications, giving you peace of mind in your network infrastructure.


Versatile Applications Across Industries

The 400GBase-QSFP-DD LR4 10km optical module finds applications across a diverse range of industries. In data centers, where high-speed data transmission between servers, storage systems, and switches is critical, this module enables efficient data exchange, supporting the growing demands of cloud computing, big data analytics, and artificial intelligence.


Telecommunications providers benefit from its long-range transmission capability, using it to enhance their backbone networks and connect remote sites with high bandwidth. Enterprise networks, especially those in large organizations with multiple locations, rely on this module to ensure seamless communication and data transfer between offices, supporting business-critical operations.


Additionally, the module is well-suited for use in research and education networks, where the transmission of large datasets and high-definition video streams is common. Its ability to handle high data rates over 10km makes it an ideal choice for connecting research facilities, universities, and academic institutions.
