The Cisco 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 for 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.
Features and benefits of Cisco QSFP-DD modules

The Cisco QDD-2X100-CWDM4-S Module supports link lengths of up to 2km SMF and uses a dual duplex CS connector. It is compliant to 100G-CWDM4 MSA. The 100 Gigabit Ethernet signal is carried over four CWDM grid optical wavelengths at 25Gb/s each. Multiplexing and demultiplexing of the four wavelengths are managed within the device. FEC is performed on the host platform.
