Description
This Juniper QDD-400G-DR4 transceiver module represents the cutting edge of high-speed networking, offering a massive 400Gb/s data rate. The QSFP-DD (Quad Small Form-factor Pluggable Double Density) form factor is designed to accommodate the increased density and power requirements of 400Gb/s interfaces, featuring an extended connector side compared to standard QSFP28. The DR4 designation indicates that the module uses four parallel optical lanes, each operating at 50Gb/s, to achieve the aggregate 400Gb/s speed. These lanes are transmitted over single-mode fiber. The 1310nm wavelength is used for these transmissions. The MPO (Multi-fiber Push On) connector is standard for DR4 modules, as it is required to accommodate the multiple fiber strands needed for the parallel optics. Designed for short-reach applications within data centers, the typical maximum transmission distance for a 400GBASE-DR4 module is around 500 meters. This makes it ideal for switch-to-switch or switch-to-server connections within a rack or across adjacent racks. The module's high bandwidth and density are crucial for supporting the ever-increasing demands of modern data center networks, cloud computing, and AI/ML workloads.
