It integrates a 7 nm coherent DSP ASIC with best-in-class ultra-narrow linewidth tunable lasers, high-speed modulators, and high-responsivity coherent receivers to deliver high performance using 400G DP-16QAM modulation. The module is designed for 400G DWDM data center interconnect (DCI) applications, supporting up to 40 km unamplified transmission without inline chromatic dispersion compensation.\n\nThe QSFP-DD 400G ZR is widely deployed in hyperscale data centers to enable high-performance edge interconnection. It supports multiple network topologies, including point-to-point, star, and ring architectures.","brand":"SFPS","offers":[{"title":"QDD-400G-ZR","offer_id":47933659545821,"sku":"5850-SFPS-QDD-400G-ZR","price":9749.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/7539\/1197\/files\/Product1883-1.png?v=1779064988","url":"https:\/\/www.sfps.qa\/products\/5850-sfps-qdd-400g-zr","provider":"SFPS.QA","version":"1.0","type":"link"}
