The Temperature Test Of Hydrogen Flame In The Burner Producing Fbt Optical Fiber Splitter

Fused biconical tapered (FBT) fiber splitter is broadly used as basic optical passive devices in the fiber communication systems. Based on the consideration of the environment, raw material and its cost, there are most and most demand of the fused biconical tapered single-mode optical fiber splitter, especially with the development of the broadband optical communication、fiber to the home project (FTTH) and the combination of three nets recently. The CW200-B melt drawing machine system was widely used to make the fused biconical tapered fiber-optical devices now. It uses the pre-mixture of combustible gas and oxygen or combustion gas burns in air as the heating source. As the diameter of burner is only a few millimeters, the combustion flame is difficult to be controlled.In this paper, we use three diameter burners to make different flow of hydrogen burn in the air, and do a lot of testing and analysis to the temperature distributions and the hydrogen combustion flame stability. It plays a guidance role in the production of fiber splitter.In the first part of this paper, we briefly discuss the origin and production process of the fused tapered optical fiber splitter; In the second part, introducing the coupled mode theory including the theory of strong fusing and weak fusing and analyses the thermodynamic theory during the bused biconical taper; In the third part, introducing the Temperature method in a variety of special temperature conditions. According to the previous experiences, the Article designed the most cost-effective measurement methods. In the last part of this paper, the temperature distribution of hydrogen combustion in handstand micro-burner is tested by K-type thermocouple. And the micro-burner’s diameter is4mm,6mm and10mm respectively. We test the temperature distribution with the hydrogen flow of120sccm,150sccm and220sccm using that three micro-burners respectively. In the condition of the10mm diameter of micro-burner and the150sccm,190sccm and220sccm of hydrogen flow, the two modes of a single fiber diameter changing are gained. Then the error of temperature data tested by thermocouple is analyzed.
