Cutting device of high-precision optical fiber length and cutting method thereof

Abstract

The invention discloses a cutting device of high-precision optical fiber length, which is characterized by comprising an optical fiber cutter and a high-precision optical fiber displacement platform which comprises an optical fiber cutter stationary fixture, an optical fiber propelling platform and a high-precision propelling reading mechanism; the optical fiber cutter is tightly fixed at the left side of the high-precision optical fiber displacement platform through the stationary fixture, and comprises a cutter blade and a pressing broken arm matched with the cutter blade to work; the optical fiber propelling platform is arranged at the right side of the high-precision optical fiber displacement platform by the high-precision propelling reading mechanism, and can drive the optical fiberwhich is to be cut with a fixed upper part, to precisely move to the direction of the optical fiber cutter under the action of the high-precision propelling reading mechanism. The device overcomes the defects in the prior art, and can realize cutting precision at 0.01mm magnitude.

Description

technical field [0001] The invention relates to the field of optical fiber technology, in particular to a high-precision optical fiber length cutting device and a cutting method thereof. Background technique [0002] The optical fiber delay line is a component that provides an accurate delay for optical signals, and is mainly used for optical signal delay and buffering. The delay accuracy of an optical fiber delay line is mainly limited by the accuracy of the delay fiber length. In the fiber delay line, the high-precision cutting of the fiber length is the key technology. [0003] Such as figure 1 It is a typical optical fiber cleaver, which mainly includes three parts: optical fiber clamp, blade and crushing arm. The steps of the cutting operation of the optical fiber cleaver are: first clean the cutting blade and the optical fiber to be cut, place the optical fiber on the V-shaped groove of the optical fiber cutter and fix it with a clamp, and adjust the position of the...

Problems solved by technology

This method has the advantage of simple operation, but the cutting accuracy is low, generally only on the order of millimeters, which can meet the technical requirements of general optical fiber connection, but cannot meet the connection of higher fiber length accuracy, so a high-precision cutting method is required. Optical fiber cutting method, the present invention just launches at this point
