Juniper OSFP-2X400G-LR4-P 2x400G LR4 10 km | OSFP, Enterprise

Move more traffic across fewer links with a dual 400G LR4 optical module designed for long-reach enterprise and data center transport. The OSFP-2X400G-LR4-P delivers 2 x 400G connectivity over duplex LC fiber, supporting up to 10 km for aggregation and backbone deployments that need both distance and density. This module is built for environments where port efficiency matters. By combining two 400G lanes in a single OSFP form factor, it helps reduce switch port pressure while preserving the throughput required for high-volume east-west and north-south traffic. The LR4 optical design is well suited to structured fiber runs between racks, rows, and buildings where multimode optics are not enough. Standard-temperature support makes it a practical fit for controlled enterprise installations. For teams planning upgrades around Juniper platforms, this optic provides a clear path to higher-capacity links without changing the physical fiber strategy already in place. It is the kind of component that earns its place in networks where uptime, reach, and port economics all matter.
