Line fault detection method and device

Abstract

The invention discloses a line fault detection method and device, which are used for solving the problem that the existing line fault detection device can only detect whether an optical fiber line isconnected or disconnected and cannot judge the reason causing the optical fiber line disconnection. Through the arrangement of the ion air knife and the first lead screw motor, when it is detected that the optical fiber crystal head is inserted into the optical fiber socket, the crystal head elastic piece presses the induction switch, the ion air knife blows out high-pressure airflow with currentelectrons, the high-pressure airflow enables tiny attachments attached to the crystal head to be blown out of the optical fiber crystal head, and the purpose of cleaning the optical fiber crystal headis achieved. Meanwhile, a first lead screw motor drives an ion air knife to blow air up and down at a constant speed, so that tiny attachments adhered to the crystal head are further blown out of theoptical fiber crystal head, and the problem that an existing line fault detection device does not have the function of cleaning electrified tiny attachments is solved; and through the arrangement ofthe sprayer and the rotating plate, the sprayer sprays a cleaning agent stored in the high-pressure water tank onto the crystal head, and stains attached to the crystal head are flushed.

Description

technical field [0001] The invention belongs to the field of optical fiber inspection, relates to an optical fiber line fault detection technology, and specifically relates to a line fault detection method and device. Background technique [0002] The tiny fiber is encapsulated in a plastic sheath that allows it to be bent without breaking. Typically, a transmitting device at one end of the fiber uses light emitting diodes and / or a laser to transmit pulses of light into the fiber, and a receiving device at the other end of the fiber uses a photosensitive element to detect the pulses. [0003] During the manufacturing process, optical fibers can become contaminated and / or damaged. For example, optical fibers may chip, crack or splinter during the cleaving process. Other processes, such as stripping, cleaning, etc., can leave particulate or fluid contamination on the fibers. Such damage and / or contamination can degrade the signal quality of optical signals transmitted over ...
