Abstract
The present invention relates to a method for terminating the end of an optical fiber. In particular the present invention relates to a method for forming a low reflectance termination on an end of an optical fiber. The method including the step of tensioning the optical fiber between two spaced apart points thereon. The method further including the step of moving a ball termination torch from a given location in a given direction with respect to the fiber such that a potion of the flame therefrom intercepts the fiber and severs the fiber into two pieces each having a tapered end. The method further includes the steps of retracting at least one of the tapered ends a predetermined distance in a direction away from the other of the tapered ends and continuing to move the torch such that the flame heats the at least one of the tapered ends to cause it to become shortened.
