The US Transceivers compatible QDD-400G-DR4-AR is a 400GBASE-DR4 QSFP-DD optical transceiver designed for high-density 400G deployments. Operating over single-mode fiber, this module utilizes four parallel lanes of 100G each at 1310 nm using PAM4 modulation, supporting link distances up to 500 meters. The QSFP-DD form factor delivers exceptional port density for modern high-performance switching and routing platforms.
This TAA compliant module is engineered to meet IEEE 802.3bs and QSFP-DD MSA standards, ensuring reliable interoperability in demanding network environments. It features Digital Diagnostic Monitoring (DDM) for real-time visibility into key optical parameters including temperature, voltage, TX power, and RX power.
The US Transceivers compatible QDD-400G-DR4-AR is an ideal solution for data center interconnect, high-performance computing fabrics, cloud infrastructure, and enterprise core networking, delivering carrier-grade performance at a cost-effective price point.
