Description
The AddOn Juniper Networks® QDD-400G-PLR4-AO is a high-performance, hot-pluggable 400GBase-PLR4 QSFP-DD transceiver designed for modern data centers and high-speed network applications. Delivering 400 Gbps Ethernet throughput up to 10 km over single-mode fiber (SMF) via an MPO connector, this module uses a 1310 nm wavelength and fully complies with INF-8628 standards.
Each unit is programmed, uniquely serialized, and data-traffic tested to guarantee 100% compatibility and seamless interoperability with Juniper Networks® equipment. Digital Optical Monitoring (DOM) provides access to real-time performance metrics, while CMIS 4.0 support ensures reliable management and monitoring.
Built for reliability and ease of deployment, this TAA-compliant transceiver features excellent ESD protection, low EMI, and RoHS-compliant, lead-free construction, making it an ideal solution for large-scale switching, routing, and data center interconnect environments.
