Abstract: An optical fiber array, wherein a preset number of optical fibers (13) are fixed by a substrate (12) and a lid plate (11) each provided with V-grooves, and the distribution of fiber cores of the preset number of optical fibers (13) on a port cross-section of the optical fiber array matches a preset curve, such that light beams transmitted and output through the optical fiber array are not transmitted on the same plane, and correspond to required positions on the preset curve. Accordingly, the optical fiber array meets application requirements of a novel WSS system, and can be widely used in the novel WSS system and in other scenarios having special requirements of light beam positions.

Abstract: The present application provides a fiber array for vertical coupling, including an optical fiber, an L-shaped plate, a U-shaped cover plate and a V-shaped slot; wherein the optical fiber includes a straight section, a curved transition section and a curved fixed section that are sequentially connected; the curved transition section of the optical fiber is arranged on an outer side surface of the L-shaped plate, the straight section of the optical fiber is fixedly arranged at a horizontal end of the L-shaped plate through the U-shaped cover plate, and the curved fixed section of the optical fiber is fixedly arranged on a curved end of the L-shaped plate through the V-shaped slot. The fiber array for vertical coupling provided by the present application can greatly reduce the optical loss in the light path.
