摘　　要：Optical fiber transmission has been widely used in communications and metrology,wherein optical frequency transfer(OFT)and optical physical layer secure key distribution(OKD)have become research hotspots^([1,2]).Moreover,OFT can perform a comparison between state-of-the-art optical atomic clocks and implement coherent optical phase transfer over long distances to support geodesy^([1,3]).
