Description

Technical Field

[0001] The utility model relates to the technical field of communications, in particular to an optical fiber connector. Background Art

[0002] Fiber optic connectors are devices that make detachable (movable) connections between optical fibers. They precisely connect the two end faces of the optical fiber so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. SC is a relatively common fiber optic connector, which is most commonly used on router switches and optical interfaces on the transmission equipment side. The SC connector can be directly plugged in and out of the adapter interface on the transmission equipment, which is convenient to use. The disadvantages of traditional SC connectors are: poor structural strength. It is mainly suitable for soft optical cables, but there will be major problems when used on hard optical cables. For example, when twisting the optical cable during construction, it is easy to cause torsion between the stopper and the connector body, which in turn causes damage to the optical cable.
