Method, system and optical fiber adapter for detecting connection state of optical fiber

Abstract

The invention discloses a method for detecting the connection state of an optical fiber, which comprises the following steps: setting a sensor element in an optical fiber adapter, wherein the sensor element is prevented from contacting with the optical fiber neither when the optical fiber is plugged in the optical fiber adapter nor when the optical fiber is pulled out of optical fiber adapter; and detecting the change of the parameters of the sensor when the optical fiber is plugged in or pulled out of the optical fiber adapter and determining the connection state of the optical fiber according to the result of the detection. Correspondingly, the invention also discloses a system for detecting the connection state of the optical fiber and the optical fiber adapter. The method adds a non-contact sensor in the prior commercial optical fiber adapter and is simple in implementation, high in reliability and excellent in environmental adaptability.

Description

technical field [0001] The invention relates to the communication field, in particular to a detection method, system and optical fiber adapter for optical fiber connection status. Background technique [0002] Passive Optical Network PON (Passive Optical Network) consists of an optical line terminal OLT (Optical Line Terminal) on the office side, an optical network unit ONU (Optical Network Unit) or an optical network terminal ONT (Optical Network Terminal) on the user side, and an optical distribution network ODN (Optical Distribution Network) composition. The traditional ODN is composed of pure passive devices, which are mainly divided into optical fiber cables, branch devices, connecting devices and supporting devices in terms of functions. Among them, fiber optic cables are mainly divided into feeder cable sections, distribution cable sections and home cable sections, etc. Branch devices mainly include wavelength division couplers and power couplers (Power-Splitting Spl...
