Technical Field
The invention relates to the technical field of information communication, in particular to an optical fiber array consisting of high-precision ceramic plug components.
Background
A Fiber Array (Fiber Array) is an Array formed by mounting a bundle of optical fibers or an optical Fiber ribbon on a substrate at a predetermined interval using a V-Groove (i.e., V-Groove) substrate, and is mostly applied to a planar optical waveguide, an Array waveguide grating, see fig. 2; active/passive array optical fiber devices, micro-electro-mechanical systems, and multi-channel optical modules. The processing of the optical fiber array, which is common in the prior art, is such that the bare fiber portion from which the optical fiber coating is removed is placed in the V-groove, pressed by a presser member, and bonded by an adhesive, and finally the surface is ground and polished to a desired precision. At the front end, the fiber is precisely positioned for connection to the PLC. Splices of different optical fibers are mounted on the substrate. However, the ceramic fiber array manufactured in this way is difficult to mass-produce, the processing accuracy is slightly inferior to that of the glass fiber array, and the positions of the fiber cores with respect to the outer diameter are difficult to be uniform in both the glass fiber array and the ceramic fiber array, so that it is difficult to finely adjust the positions of the fiber cores.

In order to achieve the purpose, the optical fiber array formed by the high-precision ceramic plug components comprises a rear seat; the high-precision ceramic ferrule optical fiber assembly is of a two-section structure, the outer diameter of the front section of the high-precision ceramic ferrule optical fiber assembly is larger than that of the rear section, an optical fiber channel is arranged in the high-precision ceramic ferrule optical fiber assembly and is of a two-section structure, and the diameter of the front section of the optical fiber channel is smaller than that of the rear section; a plurality of high-precision ceramic core-inserted optical fiber assemblies are connected together through a rear seat to form an optical fiber array.
The invention also has the following preferable technical scheme:
furthermore, the rear section of the optical fiber channel is provided with a V-shaped groove, and the joint of the optical fiber channel is provided with an R angle transition.
Furthermore, the lower part of the outer edge of the high-precision ceramic ferrule optical fiber assembly is tangent to the surface of the positioning jig.
Furthermore, glue is adopted between the rear section structures of two adjacent high-precision ceramic ferrule optical fiber assemblies for final positioning, and assembly tolerance is absorbed.

Referring to fig. 1, fig. 1 provides a schematic structural diagram of an embodiment of an optical fiber array composed of high-precision ceramic ferrule optical fiber assemblies, in which the optical fiber array is split into a plurality of high-precision ceramic ferrule optical fiber assemblies.
The high-precision ceramic core-inserted optical fiber assembly is of a two-section structure, a V hole deepening structure can be used, and the same effect can be achieved by adding R angle replacement at the joint.
A plurality of high-precision ceramic core-inserted optical fiber assemblies are connected together through a rear seat to form an optical fiber array.
The distance between the optical fiber arrays is the same as the outer diameter of the ceramic ferrule, the external dimension is defined by the base, and the position of the boundary of the outer diameter of the ceramic ferrule is directly grabbed by positioning identification during coupling of the optical fiber arrays.
Referring to fig. 3, the lower part of the outer edge of the ferrule assembly is tangent to the surface of the positioning jig to ensure the height of the fiber core.
Referring to fig. 4, the clearance fit between the ferrule assemblies is finalized with glue to absorb assembly tolerances
The eccentricity between the fiber core and the outer diameter of the ceramic optical fiber component adopting the core adjusting technology in the prior batch production is less than 1um, and when all the optical fiber components are adjusted to the same sector, the eccentricity in the up-down direction is superior to the position degree of 0.7um of the prior optical fiber array
When all ferrule assemblies are horizontally tiled and abutted, the pitch dimension meets the highest tolerance requirement of 0.7um due to the diameter tolerance of the ferrules being 0.5 um.
