Multi-optical fiber synchronous and automatic coupling device

The present invention relates to an optical fiber light path coupling technology field, in particular to a multi-optical fiber synchronous and automatic coupling device. The multi-optical fiber synchronous and automatic coupling device comprises a grating filter used for selecting the wavelengths of the outputted optical waves, an automatic coupler used for automatically coupling the optical waves outputted by the grating filter, a control device matching the automatic coupler and adjusting the light paths automatically, a multi-core optical fiber collimator used for transforming the light outputted by the automatic coupler into the parallel light and a lens used for focusing the parallel light outputted by the multi-core optical fiber collimator on a multi-core optical fiber, wherein the automatic coupler comprises a light beam splitter, a light beam combiner and multiple sets of prisms and MEMS reflectors which are integrated on a PCB, each prism and each reflector are arranged relatively, and the prisms an
