Juniper OSFP-2X400G-DR4-P 2x400G OSFP | 800G, DR4, Enterprise

Sustain dense routing and switching fabrics with an OSFP module designed for 2 x 400G DR4 transport. Built for environments where port density, thermal control, and predictable optical performance matter, this Juniper transceiver supports 500 m reach over multimode fiber and uses dual MPO-12 connectivity for parallel optics deployment. The OSFP form factor is suited to high-capacity platforms that need to move more traffic without expanding rack footprint. Dual 400G lanes help preserve throughput for east-west traffic, storage replication, and large-scale cluster interconnects. For teams planning around growth, this module provides a clear path to higher aggregate bandwidth while keeping cabling structured and short-reach efficient. Choose this optic when you need a deployment that aligns with modern 800G-class infrastructure planning and the operational discipline of parallel-fiber design. It is a strong fit for data center cores, high-performance computing fabrics, and routing environments where link consistency and port utilization directly affect service quality.
