$1,227.50

SKU: QDD-400G-XDR4-US Categories: , , OEM Equivalent: Arista QDD-400G-XDR4

The US Transceivers compatible QDD-400G-XDR4 is a high-performance 400GBASE-DR4+ QSFP-DD transceiver designed for high-density 400G optical interconnects. Operating over single-mode fiber with four parallel lanes at 100G per lane, this module transmits at 1310 nm wavelength and supports link distances up to 2 km, making it well suited for extended campus and data center reach applications beyond standard DR4 specifications.

This QSFP-DD form factor module features an MPO/MTP connector interface and leverages PAM4 modulation to deliver 400Gbps aggregate throughput. It includes Digital Diagnostic Monitoring (DDM) for real-time visibility into key optical parameters such as temperature, voltage, transmit power, and receive power, enabling proactive network management and simplified troubleshooting.

The US Transceivers compatible QDD-400G-XDR4 is TAA compliant and manufactured to meet industry standards for reliability, performance, and interoperability, providing a cost-effective alternative for enterprise core networks, hyperscale data centers, and high-speed interconnect deployments.
