SFP-DD optical module, SFP-DD optical module, SFP-DD high-speed optical module, SFP-DD high-speed optical module:

　　Designed to develop a specification for a high-speed, double-density Small Form-Factor Pluggable (SFP-DD) interface. It plans to create a double-density SFP size optical module for 50Gbps and 100Gbps data center network applications. The optical module will use NRZ or PAM4 modulation depending on the data rate, will utilize a 25Gbps NRZ or 56Gbps PAM4 electrical interface, and support 50Gbps, 112Gbps applications through a pair of transmission lines. The first market target of SFP-DD is the server side, and with QSFP-DD on the switch side, the total port density can be doubled. Network equipment based on the SFP-DD specification will support traditional SFP modules and cables, as well as new double-density products
