Designed for high-density data centre spine-leaf fabrics, HPC clusters, and AI\/ML interconnect deployments, it enables native 800G to 2x 400G breakout without requiring external optical breakout cables — simplifying cabling infrastructure and reducing operational overhead.\u003cbr\u003e\u003cbr\u003eOperating at dual-rate (2x 400GBASE-LR4 or 2x 200GBASE-LR4), this module uses 8x optical lanes with 100G PAM-4 modulation and consumes just 16W. It interoperates with 400G-LR4 OSFP and QSFP-DD peers as well as 200G-LR4 QSFPs, and the QSFP-DD form factor retains backwards compatibility with 40G and 100G QSFP modules. Part of Arista's comprehensive 800G optics portfolio, it is the ideal choice for organisations scaling toward 800G network infrastructure.
