ABSTRACT:
An apparatus for fabricating an optical fiber coupler having a well-controlled quality and an improved packaged strength is provided. The apparatus includes a holding device holding thereon a quartz tube sleeving therein an optical fiber strand having a spliced portion to be fused, two pulling stages oppositely pulling the fiber strand, a heating device having two torch blowpipes for heating through the quartz tube the spliced portion, a first driving mechanism for oppositely translating the pulling stages, a second driving mechanism for reciprocatingly translating the blowpipes along the quartz tube, and a programmable controller coupled to and for controlling the heating device, the first and the second driving mechanisms. A method for fabricating the optical fiber coupler is also disclosed.
