Problems solved by technology
[0009] It can be seen that the above-mentioned existing optical fiber array substrate and its manufacturing method obviously still have inconvenience and defects in structure, method and use, and need to be further improved urgently.
In order to solve the problems existing in the optical fiber array substrate and its manufacturing method, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure for general products. The above-mentioned problems are obviously the problems that relevant industry players are eager to solve

Embodiment Construction
[0109] In order to further illustrate the technical means and effects that the present invention adopts to achieve the intended purpose of the invention, below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure, The method, steps, features and effects thereof are described in detail below.
[0110] Fig. 1 is a substrate 11 for an optical fiber array according to the first embodiment. The substrate 11 for the optical fiber array is made of, for example, transparent borosilicate glass, and is provided with eight grooves (for example, V-shaped grooves) 12 on one side of which eight core optical fibers 14 are arranged and fixed side by side. The V-groove-shaped side groove portion 13 is located outside the outermost V-groove 12 on both side surfaces of the substrate 11 . In addition, in this embodiment, the side surfaces 11a and 11b of the substrate 11 parallel to the groove portion 12 are respectively formed in the cen...

Abstract
The invention relates to an optical fiber array substrate and a method for producing the same. The optical fiber array substrate (11) has (8) V-shaped grooves (12) on its one surface for fixing (8)-core optical fibers (14) arranged in parallel to one another and V-shaped side groove portions (13) formed outside of the outermost V-shaped grooves (12) located in the vicinity of the both sides of the substrate (11). The outer hunches (12c, 12d) forming the outermost V-shaped groove (12) have a summit of an identical height to the summit (12a) of the inner heap and the bottom (13a) of the side groove portion (13) has a height lower than the contact point (12e) between the ridge of the V-shaped groove (12) and the optical fiber (14).
Description
[0001] This case is a divisional application of a patent application whose application number is 038057999, the application date is March 14, 2003, and the invention name is a substrate for optical fiber array and its manufacturing method. technical field [0002] The present invention relates to a substrate for an optical fiber array and a manufacturing method thereof, in particular to a substrate for an optical fiber array that is used in an optical device for connecting multiple optical fibers and is formed with fixing grooves capable of accommodating multiple optical fibers and positioning them. Manufacturing method. Background technique [0003] In recent years, the demand for larger capacity and higher speed of optical communication networks has become higher and higher, and optical fiber array optical devices have attracted attention. For the alignment and positioning of multiple such optical fibers, a substrate with a straight V-shaped groove is generally used. The m...
