Enhanced optical time-domain reflectometer resolution using depolarization of light source |
摘要 |
Described herein are systems and methods for enhancing the resolution of an optical time-domain reflectometer (OTDR). One embodiment of the disclosure of this application is related to a device, comprising an optical measuring component collecting a first set of measurement data from a forward trace along an optical fiber with the optical measuring device using depolarized light, and a processing component calculating loss along the length of fiber. The optical measuring device further collects a second set of measurement data from a backward trace along the optical fiber with the optical measuring device using depolarized light. |
