The subject matter herein generally relates to optical fiber array devices and an optical fiber array.
Generally, optical fiber array devices includes a plurality of optical fibers. However, in the related art, a positional accuracy of the optical fibers may be lower than desired.
Implementations of the present disclosure will now be described, by way of embodiments, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. Additionally, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other word that “substantially” modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
Referring to
The substrate 10 has a substantially rectangular cross-sectional shape. The cover plate 20 has a substantially rectangular cross-sectional shape.
The ceramic ferrule layers of the ceramic ferrule array 30 are stacked in the receiving groove 11. The receiving groove 11 has a substantially rectangular cross-section. The receiving groove 11 further includes a bottom wall 113 perpendicularly connected to the first groove wall 111 and the second groove wall 112. One of the plurality of ceramic ferrule layers abuts against the bottom wall 113, and another one of the plurality of ceramic ferrule layers abuts against the cover plate 20.
In one embodiment, a center of each ceramic ferrule 31 in each ceramic ferrule layer is aligned with a center of at least one ceramic ferrule 31 in another ceramic ferrule layer.
In one embodiment, a gap exists between adjacent ceramic ferrule layers, and a size of the gap is set according to a size of the positioning members 40. When an outer diameter of the ceramic ferrule 31 in the ceramic ferrule layer is changed, a pitch of an optical fiber cable inserted into the ceramic ferrule 31 correspondingly changes. It should be understood that a size of the positioning member 40 and the outer diameter of the ceramic ferrule 31 can be adjusted according to actual needs to adjust the gap between the adjacent ceramic ferrule layers and adjust a spacing of the fiber optic cables inserted into the ceramic ferrules 31.
In one embodiment, each ceramic ferrule 31 in each ceramic ferrule layer 30 abuts against an adjacent ceramic ferrule 31.
In one embodiment, the ceramic ferrule array 30 includes four ceramic ferrule layers, and each ceramic ferrule layer includes five ceramic ferrules 31. In other embodiments, a quantity of the ceramic ferrule layers and the ceramic ferrules can be changed according to actual needs.
The positioning member 40 has a substantially circular cross-section. Each of the positioning members 40 is located between two adjacent ceramic ferrule layers, and each positioning member 40 simultaneously abuts two adjacent ceramic ferrules 31 of each adjacent ceramic ferrule layer. Specifically, opposite sides of the positioning member 40 respectively abut the outer surfaces of two adjacent ceramic ferrules 31 of the adjacent two ceramic ferrule layers 30.
In one embodiment, a center of each positioning member 40 is symmetrically located between the adjacent two ceramic ferrules 31 of the adjacent two ceramic ferrule layers.
Opposite sides of the ceramic ferrule array 30 respectively abut the first groove wall 111 and the second groove wall 112, and each positioning member 40 abuts two adjacent ceramic ferrules 31 of two adjacent ceramic ferrule layers to fix the ceramic ferrules 31. The optical fiber array device 100 has a simple structure, low production cost, and good optical signal transmission quality.
In other embodiments, a gap exists between adjacent ceramic ferrules 31 in each ceramic ferrule layer.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
