Use Cases
The XVR-10079-20 Arista 100GBASE-PSM4 QSFP Optical Module is primarily deployed in high-density data center environments where extended reach connectivity is required over parallel single-mode fiber. Network architects and IT teams benefit from its ability to maintain 100 Gigabit Ethernet speeds across distances up to 500 meters, supporting scalable and flexible infrastructure layouts. How It's Used: Connecting switches across multiple data center racks to optimize server-to-server communications within a centralized facility. Linking separate data center buildings or campus environments where fiber runs exceed typical copper or short-range optics limitations. Extending the reach of storage area networks (SANs) that require high-bandwidth, low-latency links over longer distances than traditional multimode fiber supports. Facilitating virtualized workloads by providing reliable high-speed interconnects between compute clusters and network aggregation points. Supporting edge computing nodes that need robust uplinks to core data center resources across campus fiber infrastructures. By enabling 100G connections over parallel single-mode fiber at extended distances, this optical module enhances data center operational efficiency and scalability. It supports modern network designs that demand both high throughput and flexible deployment options without sacrificing performance.
