US 2016/0259133 A1 · Optical Coupler For Multicore Fiber

Abstract

[Problem] To provide a connector whereby rotation of a multicore fiber does not occur. [Solution] An optical connector (17) of the present invention includes a ferrule (13) that holds a multicore fiber (11), and a plug frame (15) equipping the ferrule (13) housed therein. The ferrule (13) has at least one flat surface (19) on the outer circumferential surface thereof, and the plug frame (15) has a plate spring structure (21) to apply pressure on the flat surface (19). In the optical connector (17) of the present invention, the plate spring structure (21) is casted in the plug frame (15).
