Abstract
In this paper, we have presented techniques to reduce the splicing loss between standard single mode fiber and high ${\Delta}$ single mode fiber based on the mode expanding and mode evolution induced by thermal treatment of the fibers. The experimental results show that mechanical splicing loss can be reduced from 2.3 dB to 0.1 dB through proper thermal treatment of the high ${\Delta}$ fiber. Meanwhile, we achieved $0.2{\sim}0.4dB$ of low splicing loss between two fibers by heating the splicing region using electric arcing or an oxygen flame.
