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.\u003c\/p\u003e\u003cp\u003e\n\n\u003c\/p\u003e\u003cp\u003eFyber Optix is a British-engineered brand of OEM-compatible optical networking products, including SFP, SFP+, QSFP+, QSFP28 and QSFP-DD transceivers, DWDM\/CWDM systems, media converters, and DAC\/AOC cables. Every module is 100% pre-shipment tested and coded for seamless compatibility with major platforms such as Cisco, Huawei, Juniper, Arista, HPE, Dell, Nokia and Fortinet — backed by a lifetime warranty, fast global delivery, and dedicated technical support for data centers, telecom operators, enterprise networks and system integrators worldwide.\u003c\/p\u003e","brand":"Fyber Optix","offers":[{"title":"QDD-400G-FR4","offer_id":46161054564399,"sku":"FO-QDD-400G-FR4-172654","price":959.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0667\/9435\/6783\/files\/Product5275-1.png?v=1789098619","url":"https:\/\/www.fyberoptix.com\/products\/fo-qdd-400g-fr4-172654","provider":"Fyber Optix","version":"1.0","type":"link"}
