Method and apparatus for cleaving and chamfering optical fiber

摘要

A process and apparatus for cleaving an optical fiber are provided. The process includes window stripping the optical fiber using a laser source to create a window strip. The window stripped optical fiber is then scribed at a position within the window strip and tension is applied to the optical fiber. The cleaved optical fiber can be chamfered by applying a heat source to the cleaved end face. The above process and apparatus provide a high precision and inexpensive system for fiber cleaving and chamfering.

1. A process of cleaving an optical fiber, the process comprising:
window stripping the optical fiber using a laser source to create a window strip; scribing the window stripped optical fiber at a position within the window strip; and applying tension to the optical fiber, wherein the window stripping comprises:
focusing a laser beam output by the laser source through focusing optics;placing the optical fiber in the path of the laser beam away from the focal point of the focusing optics; andexposing the optical fiber to the laser source for a predetermined exposure time, thereby creating the window strip, wherein the cleaved optical fiber obtained as a result of the scribing and applying the tension has an end face strip back smaller than 300 microns.
