Migrate to 400G connectivity with QSFP-DD modules that provide super-high density and backwards compatibility.
Cisco 400G QSFP-DD Cable and Transceiver Modules Data Sheet
سيسكو®family of QSFP-DD modules provide the industry’s highest bandwidth density while leveraging the backward compatibility to lower-speed QSFP pluggable modules and cables.
The Cisco 400GBASE Quad Small Form-Factor Pluggable Double Density (QSFP-DD) portfolio offers customers a wide variety of super high-density transceiver modules and the flexibility of 400 Gigabit Ethernet connectivity options fo r data center, high- performance computing networks, enterprise core and distribution layers, and service provider applications. The QSFP-DD modules are our new generation of 400G transceiver modules based on a QSFP-DD form factor.
