Embodiment Construction

[0014] specific implementation plan

[0015] The invention regulates the flame temperature, the swing amplitude and the pulling speed of the optical fiber during the whole process of manufacturing the coupler. Figure (1) is a system block diagram of the present invention. Once the fusion drawer starts to run, the initial height d of the flame 50 leaving the fiber heating zone after it is put in place according to the preset gas and oxygen flow rates is 0 and initial swing heating while platform S 1 , S 2 pull speed V from rest p = 0 starts with acceleration α p The optical fiber is stretched at a variable speed, and after a time t, the fiber is drawn at a constant speed V pstretch the fiber. As the melting cone area is heated and elongated, the flame swing is correspondingly increased, so that the melting cone area is always in the heating range. The setting of these parameters should ensure that the shape of the fusing cone area displayed in real ti...

Abstract

A process for preparing the melting cone device of optical fiber by dynamically regulating the drawing speed, heating temp and amplitude includes such steps as heating optical fiber with flame by a certain distance, swinging at initial speed while drawing at initial speed and acceleration, drawing at uniform speed, using CCD monitor to observe the heated region of optical fiber while regulating the relative parameters until initial control point where the couple ratio between optical fibers is 1% or more, closed-loop control to flame temp, amplitude and drawing speed, choosing proper control point, choosing swinging acceleration and speed, stopping drawing, and fast swinging flame for eliminating internal stress.

Description

technical field [0001] The invention belongs to the field of information technology, and specifically provides a new method for manufacturing a high-performance passive device fusion taper optical fiber coupler. Background technique [0002] Fused tapered optical fiber device is a very common and critical passive device used in the fields of information transmission and information processing such as optical communication systems, computer networks, cable television, instrumentation, and sensor technology. Fused tapered optical fiber devices are known for their very low additional loss. High directivity, good environmental stability, simple and flexible control method, suitable for mass production, easy to connect with optical fiber links, etc., are favored by people. After years of improvement and development, the fused taper process has become a technology that plays a pivotal role in the development of optical devices - fused optical fiber dev...
