The 400G QSFP-DD XDR4 (DR4+) module adopts a 1310 nm EML transmitter and PAM4 modulation, operating at a nominal wavelength of 1310 nm to deliver 400 Gb\/s optical transmission. The module is compliant with IEEE 802.3cu specifications for 100GBASE-FR1, as well as 400GAUI-8 and CEI-56G-VSR-PAM4 electrical interface standards.\n\nThe 400G QSFP-DD XDR4 transceiver is typically deployed for interconnecting 400G leaf switches to spine switches, or 400G QSFP-DD switches to 100G QSFP28 switches. As server network interface card (NIC) speeds continue to increase, it can also be used to connect 400G QSFP-DD switches with 400G OSFP or QSFP112 NICs. The module is widely used in high-performance computing (HPC) networks, data centers, 400G Ethernet interconnects, enterprise core and distribution layers, and service provider networks.","brand":"SFPS","offers":[{"title":"QDD-400G-XDR4","offer_id":47933658693853,"sku":"5875-SFPS-QDD-400G-XDR4","price":944.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/7539\/1197\/files\/Product1858-1.png?v=1779064949","url":"https:\/\/www.sfps.qa\/products\/5875-sfps-qdd-400g-xdr4","provider":"SFPS.QA","version":"1.0","type":"link"}
