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.\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-ER4","offer_id":46161052205103,"sku":"FO-QDD-400G-ER4-172519","price":7499.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0667\/9435\/6783\/files\/Product5251-1.png?v=1789098583","url":"https:\/\/www.fyberoptix.com\/products\/fo-qdd-400g-er4-172519","provider":"Fyber Optix","version":"1.0","type":"link"}
