Background
In optical communication products, optical fibers are often used as media, especially ribbon optical fibers, and in order to facilitate quick connection between optical cables and devices, connectors are often required to be assembled at ends of the optical cables to realize optical transmission. The number of cores of the ribbon fiber is mainly 2-12, and in order to ensure the stability and the density of butt joint of the ribbon fiber and the connector, a twelve-core MPO/MTP connector with mature technology is usually used for butt joint. When a four-core or eight-core ribbon fiber is butted with a twelve-core MPO/MTP connector, the fact that the channels in the fiber and the connector ferrule cannot be matched with each other can occur, the corresponding channel needs to be searched for automatically to penetrate the fiber, fiber dislocation is easy to cause, and the fiber is difficult to penetrate the connector ferrule quickly and accurately. Accordingly, there is a need for further improvements in existing ribbon fibers that allow for better assembly into connectors having a greater number of channels than ribbon fiber cores.
