Description
The Fortinet FN-TRAN-QSFPDD-LR4 is an advanced optical transceiver module designed for extremely high-speed networking applications, specifically at 400 Gigabits per second (Gbps). It utilizes the QSFP-DD (Quad Small Form-factor Pluggable Double Density) form factor, which allows for higher port density and increased bandwidth compared to previous QSFP generations. This module is engineered for Long Range (LR4) transmission, meaning it employs four different wavelengths (typically around 1310nm) multiplexed together to achieve the 400Gbps aggregate speed over a single pair of single-mode fiber strands. This transceiver is built to support distances of up to 10 kilometers, making it ideal for demanding data center interconnect (DCI) applications, high-performance computing (HPC) clusters, and core network aggregation. It features duplex LC connectors, which are standard for single-mode fiber connections, ensuring robust and reliable physical connectivity. The hot-pluggable nature of QSFP-DD modules allows for easy deployment and maintenance without interrupting network operations. The FN-TRAN-QSFPDD-LR4 is a critical component for network infrastructure that requires massive bandwidth and scalability. Its ability to deliver 400Gbps over 10km on single-mode fiber addresses the growing need for faster data transfer rates in modern data centers and telecommunication networks. Fortinet's implementation of this technology ensures compatibility and performance within their networking solutions, enabling next-generation network architectures.
