Improvement On The Packaging Process Of 1X2 Single Mode FBT Fiber Splitters

1X2 single-mode fiber optic splitter is one of the most important fiber optical passive components in fiber communication systems.Its characteristics have direct impacts on the performance of fiber optical communication system.1X2 single-mode fiber optic splitter plays an important role in the FTTH deployment,hence the market has great needs for the 1X2 single-mode fiber optic splitters which have both low price and high performance,.First of all,this paper introduces the basic theory of 1X2 single mode splitter,describes briefly the processing technology.Then it derives the relationship of the powers between two fiber-coupled from coupled-mode theory,and indicates the intrinsic link between parameters. Finally this paper outlines the industrial environment of 1X2 single mode fiber optic splitter.Secondly,this paper introduces the advanced production processes of 1X2 single-mode fiber optic Splitter,makes a significant improvement in the efficiency and performance. Another work in this paper is the improvement for the production processes,which include the safety operation of the equipment with hydrogen lines,the operation of vacuum pumps, the selection of fiber and plastic raw materials and the improvement in packaging processes. This paper also describe how to make the measurement on insertion loss,return loss,PDL,.At last,this paper focuses on the improvement of how to deal with the fiber-end in order to improve the return loss in detail.It first introduces the traditional process,and then improves it based on theoretical analysis.This paper then focuses on a few experiments to improve return loss,and then it compares and analyzes the experimental results with the traditional ones.Finally,it analyzes the factors which impact on return loss.Finally it finds out an efficient process to guarantee the high return loss for 1X2 single-mode fiber optic splitter.
