QSFP-40G-LR4-S= Cisco 40Gb/s 40GBase-LR4 Single-Mode Fiber 10km QSFP+ Module

The QSFP-40G-LR4-S= module is integral in environments requiring robust, long-distance 40Gb/s connectivity over single-mode fiber. It is especially beneficial in large-scale enterprise networks and data centers where high bandwidth and extended reach between equipment racks or buildings are essential.

How It's Used:

• Connecting core switches in multi-building campus networks to maintain high-speed data transfer across long distances.
• Linking storage area networks (SANs) in data centers to support high-throughput virtualization and backup workloads.
• Extending 40GbE links between data center aggregation and access layers in high-density rack deployments.
• Facilitating high-speed interconnects for edge computing nodes in distributed IT environments requiring low latency and reliable fiber connectivity.
• Supporting enterprise IT infrastructures that require scalable bandwidth upgrades without changing existing fiber cabling.

By enabling consistent 40Gb/s communication over distances up to 10 kilometers, this transceiver supports scalable network architectures. It helps maintain performance and operational efficiency in complex environments where data demand and physical separation challenge connectivity solutions.
