The invention belongs to the technical field of communication equipment, in particular to an optical fiber distribution cabinet. The cabinet comprises a cabinet body and a plurality of distribution frames in the cabinet body. A winding mechanism is disposed between the adjacent distribution frames. Each winding mechanism comprises a winding plate, a plurality of winding posts on the winding plate,a plurality of wire sorting grooves disposed on the winding plate, wherein the winding posts are arranged in two rows and multiple columns, and the wire sorting grooves are located between two columns of winding posts. Through the special design of the winding mechanisms, each two winding posts arranged at the top and bottom are set as one group, and the same group of optical fibers are wound around the same group of winding posts, thereby facilitating the reasonable winding of the remaining optical fibers, facilitating the fault inspection, greatly improving the searching speed, and shortening the fault processing time.
