Juniper JNP-QSFP-4X10GE-LR QSFP+ 40GBase-LR | Optical Fiber, Enterprise

Keep high-speed switching links stable across longer fiber runs with the Juniper JNP-QSFP-4X10GE-LR. This QSFP+ transceiver is designed for 40GBase-LR deployments on single-mode optical fiber, making it a practical fit for data center interconnects, aggregation layers, and switching environments that need predictable 40 Gigabit Ethernet performance. Built as a single-port QSFP+ module, it fits cleanly into dense switch architectures without adding unnecessary complexity. The long-reach LR profile is well suited to backbone links where multimode optics would fall short, and where teams need a transceiver aligned to enterprise switching standards. Juniper backs the module with a 1-year limited warranty, adding confidence for procurement cycles tied to production infrastructure. For organizations standardizing on Juniper switching, this module helps preserve port consistency while supporting optical network requirements that demand single-mode reach. It is a focused choice for teams that value compatibility, link reliability, and disciplined hardware selection over lower-grade alternatives.
