Description

Technical Field

[0001] The utility model relates to the technical field of single - core multimode fiber optic connector structures, and particularly relates to a single - core multimode fiber optic connector. Background Technique

[0002] The fiber optic interface is a physical interface used to connect fiber optic cables. Its principle is based on the total internal reflection that occurs when light travels from an optically denser medium to an optically less dense medium. There are usually several types such as SC, ST, FC, etc. FC is the abbreviation of Ferrule Connector. Its external reinforcement method is to use a metal sleeve, and the fastening method is a screw thread. The ST interface is usually used for 10Base - F, and the SC interface is usually used for 100Base - FX. A fiber optic connector is a device for detachably (actively) connecting between optical fibers. It precisely docks the two end faces of the optical fibers so that the optical energy output from the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and the impact on the system caused by its insertion into the optical link is minimized. This is the basic requirement for fiber optic connectors.

At this time, the pulling plate 202 will apply a pulling force to the tension spring 201 to keep it in a tensioned state;

[0033] At the same time, the wire groove 212 in the connecting block 203 is aligned with the wire groove 212 in the engaging block 215, so that the optical fiber can pass through smoothly. Finally, connect the optical fiber to the connector through components such as the optical fiber coupler 213, the connecting plate 204, and the light guide tube 206.
