Description

Technical Field

[0001] The utility model relates to the field of optical time domain reflectometers, and more specifically to an optical time domain reflectometer with a foldable bracket. Background Art

[0002] The optical time domain reflectometer is an instrument that analyzes the measurement curve to understand the uniformity, defects, breaks, joint coupling and other properties of optical fibers. It is made based on the backscattering of light and the Fresnel reverse principle, and uses the backscattered light generated when light propagates in the optical fiber to obtain attenuation information. It can be used to measure optical fiber attenuation, joint loss, fiber fault point location, and understand the loss distribution along the length of the optical fiber. It is an indispensable tool in optical cable construction, maintenance and monitoring.

[0003] At present, common optical time domain reflectometers on the market are provided with a simple bracket on the rear shell so that operators can better observe data during specific operations. For example, patent CN217159710U discloses an optical time domain reflectometer for optical cable construction, in which a U-shaped support frame is provided in the back wall of the machine body. When in use, the support frame is opened to support the machine body. However, the following problems exist when the device is in use:

[0004] First of all, the support structure is simple and relatively thin, and both the support for the body and the impact resistance to external forces during actual operation need to be improved. At the same time, in order to achieve good protection for the body, the existing optical time domain reflectometer is generally provided with a protective block or a buffer block on the surface of the body. At present, this kind of protective structure for the body is only for the body itself, and cannot well achieve the protective effect of the support structure provided in conjunction with the body. Therefore, the applicant believes that it is entirely possible to integrate the support structure and the protective structure commonly present in the existing optical time domain reflectometer, so as to improve the support of the body and its own service life while being able to achieve protection for the body.

[0005] Therefore, the utility model provides an optical time domain reflectometer with a foldable bracket. Utility Model Content
