The optical fiber coupler is a device for detachable (movable) connection between optical fibers, and precisely butt-joints two end faces of the optical fibers so that light energy output by a transmitting optical fiber can be coupled into a receiving optical fiber to the maximum extent, and the influence on a system caused by the interference of the light energy into an optical link is minimized.
The following classifications may be made depending on the fiber to be coupled: SC fiber couplers, LC fiber couplers, FC fiber couplers, and ST fiber couplers. The ST optical fiber coupler is applied to an ST optical fiber interface and is commonly used for an optical fiber distribution frame, the shell is circular, and the fastening mode is a turnbuckle. However, the existing ST fiber coupler is connected only by using a turnbuckle, which often causes looseness, and the looseness of either one end of the transmitting fiber or the receiving fiber affects the transmission of light energy.
