The present application relates to the field of optical communication technology, in particular to a three-dimensional fiber structure and a manufacturing method thereof. The three-dimensional fiber structure comprises at least two layers of fiber-in substrate, at least one layer of fiber-out substrate and a plurality of optical fibers; a first part of the optical fibers is fixed on the surface of any of the fiber-in substrates, and a second part of the optical fibers is fixed on the surface of any of the fiber-out substrates; the at least two layers of the fiber-in substrates are vertically stacked at different heights, and the plurality of optical fibers form a fiber cross area between the fiber-in substrates and the fiber-out substrates. The first part and the second part of the optical fibers are fixed on the surface of the fiber-in substrates and the fiber-out substrates respectively, and the fiber-in substrates are vertically stacked at different heights, so that a three-dimensional fiber cross area is formed between the fiber-in substrates and the fiber-out substrates, thereby meeting the requirement of three-dimensional fiber routing with a large height difference between the fiber-in and the fiber-out.
