This session shared the paper "Optical signal denoising through temporal passive amplification", which introduced the practical amplification of very small signals by using Talbot effect. In addition, this group meeting also shared the work progress of "Time reversal based optical fiber time synchronization technology", focusing on a bidirectional transmission time synchronization technology using time reversal, whose time synchronization performance index is very good. The experiment realizes the time synchronization experiment at the end of the 230km fiber link and in the middle of the link. After the sharing, the team discussed the contents of the report and analyzed the problems and shortcomings.
