{"product_id":"7794-sfps-qdd-400g-fr4","title":"Generic Compatible 400GBASE-FR4 QSFP-DD PAM4 1310nm 2km DDM\/DOM Duplex LC SMF Optical Transceiver Module","description":"\u003cstrong\u003eDescription\u003c\/strong\u003e\u003cbr\u003eNADDOD QDD-400G-FR4 optical transceiver features a duplex LC connector and supports transmission distances of up to 2 km over parallel single-mode fiber. It converts eight 50 Gb\/s PAM4 electrical signals into four CWDM optical channels, multiplexed into a single 400 Gb\/s optical link. On the receiving side, the 400 Gb\/s optical signal is demultiplexed into four CWDM channels and converted back into eight 50 Gb\/s PAM4 electrical outputs. The CWDM wavelengths are 1271, 1291, 1311, and 1331 nm.\n\nThe 400G QSFP-DD FR4 transceiver is designed specifically for interconnecting data centers, 400G Ethernet. It is typically paired with a 400G QSFP-DD network card and connected to one of the ports of a dual-port 800 Gb\/s 2x400G OSFP transceiver, making it ideal for AI Data Center (AIDC) and Data Center Network (DCN) deployments.","brand":"SFPS","offers":[{"title":"QDD-400G-FR4","offer_id":47933576085725,"sku":"7794-SFPS-QDD-400G-FR4","price":959.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/7539\/1197\/files\/Product436-1.png?v=1779063268","url":"https:\/\/www.sfps.qa\/products\/7794-sfps-qdd-400g-fr4","provider":"SFPS.QA","version":"1.0","type":"link"}
