Single-lens optical fiber fusion splicer

Abstract

The invention provides a single-lens optical fiber fusion splicer, comprising a light source, a lens, a fiber alignment module, an optical fiber, a control module, a display module and a discharge module, wherein the control module receives position information of the lens about the optical fiber, compares whether the optical fiber is aligned, performs displaying through the display module, sendsan instruction for adjusting the position of the optical fiber to the fiber alignment module, and finally sends an instruction to the discharge module for fusing the optical fiber. There is one and only one lens. The lens includes a lens group composed of five curved lenses and an imaging chip, the lens group includes three convex lenses and two concave lenses, and the imaging chip is connected tothe control module; the light path of the light source entering the lens group is disposed on the same line with the optical fiber, the lens group and the imaging chip, and the light emitted by the light source projects the axial end face of the optical fiber onto the imaging chip for imaging through the lens group.

Description

technical field [0001] The invention relates to optical imaging technology in the field of optical fiber fusion, in particular to a single-lens optical fiber fusion splicer. Background technique [0002] The silica fiber is composed of a silica core and a silica cladding formed around the core, and is wrapped and protected by the coating layer, and light is transmitted in the fiber core. In order to ensure that optical signals can be effectively transmitted over a certain distance in optical fibers, relatively short optical fibers need to be connected together. Optical fiber fusion splicer is a high-precision and practical equipment that integrates light, mechanics and electricity. It can provide fast, long-term stable and low-loss fiber joints for fiber optic erection and maintenance. The optical imaging module is an important part of the optical fiber fusion splicer. When the optical fiber fusion splicer is splicing the optical fiber, the alignment error of the two optica...
