The US Transceivers compatible QDD-400G-SR8 is a high-performance 400GBASE-SR8 QSFP-DD optical transceiver designed for short-reach multimode fiber applications. Operating across eight parallel lanes at 50G per lane, this module delivers an aggregate data rate of 400Gbps over OM4 multimode fiber at a wavelength of 850nm, supporting link distances up to 100 meters.
Built around the QSFP-DD form factor, this transceiver is engineered for high-density deployments and is fully compatible with systems designed for the Arista QDD-400G-SR8. It features an MPO/MTP connector interface suited for parallel optics infrastructure and includes Digital Diagnostic Monitoring (DDM) for real-time visibility into optical performance parameters.
This module is TAA compliant and meets RoHS, CE, and REACH regulatory standards, making it an ideal choice for data center interconnects, high-performance computing fabrics, enterprise core switching, and cloud networking environments where high bandwidth and low latency are critical.
