WHY CHOOSE THIS PRODUCT?

• Organizations choose the QSFP-100G-LR-S when they need high-speed optical connectivity over long distances without compromising signal integrity or network performance.
• Compared to short-reach or multimode optics, it extends connectivity up to metro-scale distances using single-mode fiber, reducing the need for intermediate regeneration equipment.
• It provides strong ROI by enabling infrastructure reuse, simplifying fiber planning, and supporting scalable 100G backbone expansion for evolving enterprise workloads such as cloud migration, AI data movement, and large-scale virtualization.
