In this paper, the mode field radius ofphotonic crystal fiber （PCF） is analyzed using finite element method, In order to quicken calculation speed, a fast estimation method for mode-field radius of PCF at 1550 nm is presented thereby realizing the fast estimation of splicing loss of PCF. The analysis shows that the proposed method can achieve accurate and fast splicing loss estimation of PCF.
