A preform for use in the method and the method for producing a glass component. The preform main rod having a constant outer diameter and a square bottom; And a sacrificial tip having an inner region of the hollow extending from the second end, and said first end portion on the opposite side of the first end, the first end attached to said bottom of said main rod in said second end . The sacrificial tip and having a circular cross section, the first end of the sacrificial tip has the same external diameter as the external diameter of the main rod. When the preform is heated in a furnace, the sacrificial tip is melted and the melting in the drawing bulb is drawn bulb (ie, tipping) to pull out the main load directly to the glass fiber, or tapered for subsequent fiber draw preform the produce. Compared to the cut preform to a square without sacrificing the tip, this is a waste of material as well as decreasing the drip time is important cladding to core ratio in the waveguide properties are maintained throughout the preform.
