Abstract
The invention provides an optical fiber array capable of realizing optical transmission direction bending. The optical fiber array comprises a substrate which is provided with a second mounting position and a first mounting position, wherein the second mounting position is used for placing optical fibers, and the first mounting position is used for placing the front bare optical fibers of the optical fibers. There is a position gap allowing the optical fibers to bend between the second mounting position and the first mounting position, which enables the optical transmission direction of the optical fibers in the second mounting position and the optical transmission direction of the bare optical fibers in the first mounting position to bend. The end faces of the optical fibers on a side, at the outlet end of the first mounting position, of the substrate are generally ground or cut. Because of the structure, a small optical fiber array of which the optical transmission direction can bend about 90 degrees or at any other angles is realized, the number of devices in an optical path is reduced, and the optical loss of the optical path is reduced greatly. The process is simple, and the cost is low.
