Abstract

The invention relates to an optical fiber beam expansion connector, comprising a connector casing which is provided with an optical fiber collimator mounting hole; an optical fiber collimator is arranged in the optical fiber collimator mounting hole; the wall of the optical fiber collimator mounting hole directly contacts and fits to the optical fiber collimator; and the insertion end of the optical fiber beam expansion connector and an adapter connector is the front end. In the invention, the connector casing is provided with the optical fiber collimator mounting hole in which the optical fiber collimator is arranged, the outer periphery surface of the optical fiber collimator directly contacts and fits to the wall of the optical fiber collimator mounting hole, and no part is arranged between the optical fiber collimator and the optical fiber collimator mounting hole, so that the integrated error of the product is small, the centring error between the optical fiber collimator and an adapted optical collimator is small, and the transitive quality of optical signals is high.

Description

technical field [0001] The invention relates to an optical fiber connector, in particular to an optical fiber beam expanding connector. Background technique [0002] The fiber optic beam expander connector is a high-end new type of fiber optic connector. The difference between it and the traditional contact fiber optic connector is that the contact of the fiber optic beam expander connector is an optical contact with a lens. Optical lenses can effectively expand the size of the transmitted light beam, and can efficiently transmit optical signals in a non-contact state. [0003] Based on the good beam expansion performance and non-contact connection of fiber optic beam expander connectors, this type of connector has become the first choice for use in harsh environments. Can have high reliability: even in the environment with large temperature changes and large heat changes, the connector can still transmit optical signals stably; it can also transmit optical signals stably u...
