QDD-400G-LR4-S Cisco 400Gbps 400GBase-LR4 1310nm 10km QSFP-DD Transceiver

The QDD-400G-LR4-S transceiver is primarily utilized in high-density data centers and enterprise network environments where 400Gbps throughput over long distances is critical. It is particularly suited for scenarios demanding extended reach connectivity, such as inter-building links or multi-rack communications within campus or metropolitan area networks.

How It's Used:

• Connecting distributed data center pods requiring high-bandwidth 10km links to support virtualization workloads.
• Enabling backbone interconnects in large enterprise campuses for aggregated traffic transport across fiber runs.
• Supporting high-performance computing (HPC) clusters that need reliable, low-latency, long-distance optical connections.
• Facilitating scalable network expansion in service provider environments involving edge computing nodes over single-mode fiber.
• Linking storage area network (SAN) components across geographically separated racks within data center facilities.

This transceiver contributes to operational scalability by delivering robust 400Gbps connectivity over extended distances without additional signal regeneration. Its compatibility with QSFP-DD interfaces ensures seamless integration into existing infrastructure, optimizing performance for demanding network applications.
