Externally tangent optical fiber bending radius measuring scale and measuring method thereof

Abstract

The present invention provides an externally tangent type optical fiber bending radius measuring scale and a measuring method thereof. The scale comprises an annular scale with scales, a fixed scale plate and a movable scale plate, a rotating shaft is fixedly installed in the middle of the annular scale, an optical fiber limiting groove is formed in the side wall of the rotating shaft, the rotating shaft is fixedly sleeved with the fixed scale plate, and the rotating shaft is rotatably sleeved with the movable scale plate; U-shaped clamps for positioning optical fibers are fixedly mounted at the free ends of the fixed ruler plate and the movable ruler plate, and the annular ruler is mounted in the middles of the fixed ruler plate and the movable ruler plate in a penetrating manner. Error caused by the process of finding the center of a circle in a traditional measurement method is avoided, the structure is simple, optical fiber outer side measurement is beneficial to single-person operation in a narrow operation space, and the externally tangent type optical fiber bending radius measuring scale and the measuring method thereof have the advantages of high measurement precision, convenient use and the wide measurement range.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, and relates to a circumscribed optical fiber bending radius measuring ruler and a measuring method thereof. Background technique [0002] One of the most important advantages of optical fiber is its flexibility. If the radius of curvature of the optical fiber is too small, it will cause the light propagation path to change, causing light to penetrate from the core to the cladding, and may even permeate outward through the cladding, resulting in loss of beam power and affecting communication quality; On the one hand, due to the limitations of actual on-site installation conditions (including the design requirements of the installation space, the distance close to the heating element, etc.), the installation radius of the optical fiber cannot be too large, so it is necessary to effectively measure and measure the length of the radius during the installation of the optical fiber. contro...
