It converts eight 50Gb\/s PAM4 electrical inputs into four LAN-WDM optical channels, multiplexed into a single 400Gb\/s optical signal. On the receive side, the 400Gb\/s signal is demultiplexed and converted back into eight 50Gb\/s PAM4 electrical outputs. Operating at LAN-WDM wavelengths of 1295.56, 1300.05, 1304.58, and 1309.14 nm, the module uses single-mode fiber (SMF) to minimize dispersion, making it ideal for data center interconnection and other high-performance, long-distance networking applications.\n\nThe 400G QSFP-DD ER4 optical transceiver delivers ultra-high-density 400 Gigabit Ethernet connectivity for data centers and high-performance computing (HPC) networks. It supports long-reach interconnects between 400G QSFP-DD switches, enabling flexible, reliable, and efficient device-to-device connectivity across a wide range of deployment scenarios.","brand":"SFPS","offers":[{"title":"QDD-400G-ER4","offer_id":47933658726621,"sku":"5874-SFPS-QDD-400G-ER4","price":7499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/7539\/1197\/files\/Product1859-1.png?v=1779064950","url":"https:\/\/www.sfps.qa\/products\/5874-sfps-qdd-400g-er4","provider":"SFPS.QA","version":"1.0","type":"link"}
