The FTP-100 fiber tapering system is designed to fabricate fiber taper with total maximum heating length up to 40mm and minimum taper diameter down to 1μm. In the standard configuration of the FTP-100 fiber tapering set-up, the brushing flame was lit-up by fusion of the LPG and oxygen gas. To ease the fabrication operation, a user friendly GUI is provided that the desired tapered diameter and length could be manipulated in the automation program.

A fiber taper can be fabricated by gently stretching an optical fiber while it is flame-brushed, such that the glass becomes soft. This procedure makes the fiber thinner over some length of e.g. a few millimeters or centimeters.
