Abstract
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.

An optical fiber array structure, comprising:
- a substrate;
- a cover plate covered on said substrate and defining with said substrate a longitudinal rectangular groove, said longitudinal rectangular groove defining a bottom wall and two opposite lateral contact walls respectively perpendicularly extended from two opposite lateral sides of said bottom wall;
- and
- an optical fiber cable comprising multiple optical fiber layers arranged in an array in said longitudinal rectangular groove, said optical fiber layers of optical fibers comprising a same predetermined number of optical fibers, the optical fibers of each two adjacent said optical fiber layers being 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 the other optical fiber layer, each said optical fiber layer having one lateral side thereof abutted against one said lateral contact wall of said longitudinal rectangular groove and an opposite lateral side thereof spaced from the other said lateral contact wall of said longitudinal rectangular groove by a gap.
An optical fiber array structure, comprising:
- a substrate comprising a mating face;
- a cover plate covered on said substrate, said cover plate comprising a mating face facing toward the mating face of said substrate;
- a longitudinal rectangular groove defined in between said substrate and said cover plate and surrounded by the mating face of said substrate and the mating face of said cover plate, said longitudinal rectangular groove comprising a bottom wall and two opposite lateral contact walls respectively perpendicularly extended from two opposite lateral sides of said bottom wall;
- and
- an optical fiber cable comprising multiple optical fiber layers arranged in an array in said longitudinal rectangular groove, the optical fibers of each two adjacent said optical fiber layers being 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 the other optical fiber layer, one of each two adjacent said optical fiber layers having two opposite lateral sides thereof respectively abutted against said two lateral contact walls of said longitudinal rectangular groove and the other of each two adjacent said optical fiber layers having two opposite lateral sides thereof respectively spaced from the two lateral contact walls of said longitudinal rectangular groove by a gap.
