Abstract:
1. A method of analyzing an optical fiber including a length extending between a first end and a second end of the optical fiber, the method comprising the steps of: transmitting a beam of light through the length of the optical fiber in a first direction from the first end toward the second end of the optical fiber; reflecting and focusing the light beam with a device providing a highly reflective event, the device comprising a concave reflective surface spaced apart from the second end of the optical fiber such that the light beam reflects back and is focused into the optical fiber in a second direction opposite the first direction, wherein the light beam traveling in the first direction provides a first backscatter of light that moves back in the second direction and the reflected light beam provides a second backscatter of light that moves back in the first direction; reflecting the second backscatter of light at the second end of the optical fiber back in the second direction; and identifying the second end of the optical fiber by monitoring at least the reflected light beam by monitoring the first backscatter of light, the reflected light beam, and the reflected second backscatter of light.
