Delivering 400Gbps aggregate throughput across four 100G optical channels at 1310nm, it uses PAM4 modulation with a gearbox DSP to convert 8x50G electrical lanes to 4x100G optical lanes — supporting link distances up to 2km via an MPO-12 APC connector. Its XDR4 architecture enables direct breakout interoperability with 100GBASE-FR QSFPs, making it ideal for spine-leaf upgrades, ISP aggregation, and mobile core deployments.\u003cbr\u003e\u003cbr\u003eThe hot-swappable QSFP-DD form factor is fully compliant with QSFP-DD MSA, CMIS, and 100G Lambda MSA standards, ensuring broad platform compatibility with Arista 400G switch deployments. Digital Diagnostic Monitoring (DDM) provides real-time visibility into optical performance parameters including temperature, voltage, and optical power. RoHS compliant and rated for standard 0°C to 70°C operating environments.
