An optical fiber array structure includes a substrate covered with a cover plate and defining therebetween a longitudinal rectangular groove with a bottom wall and two opposite lateral contact walls, an optical fiber cable consisting of multiple optical fiber layers arranged in an array in the longitudinal rectangular groove in such a manner that the optical fibers of each two adjacent optical fiber layers are arranged in a staggered manner so that the center of one optical fiber of one optical fiber layer is kept in alignment with the contact area between two adjacent optical fibers of one adjacent optical fiber layer. This design effectively reduces light loss, phase noise and crosstalk, improves yield rate for mass production and assures a high level of optical signal transmission quality and reliability.
