Embodiment
In order to be more clearly understood that technology contents of the present utility model, describe in detail and implement especially exemplified by following instance
Scheme is as follows：
The utility model employs the non-equidistantly fiber array scheme of more diameter optical fibers, and different depth is provided with substrate 2
With the first V-groove and the second V-groove of width, the first optical fiber 4 is provided with the first V-groove, second is provided with the second V-groove
The center of circle of optical fiber 5, the first optical fiber 4 and the second optical fiber 5 is in same level, wherein the first optical fiber 4 is TEC optical fiber, Neng Goushi
Now improve with other optical elements to coupling efficiency, reduce attenuation, improve transmission quality.The diameter of first optical fiber is less than the
The diameter of two optical fiber, the core of adjacent fiber for 0.25 ± 0.001mm or 0.48 ± 0.001mm, cover plate by optical fiber away from being fixed
Bonding agent is connected to a fixed with substrate.
It is of the present utility model to realize that step is as follows：The first optical fiber 4 and the second optical fiber 5 are discharged in sequence first,
Because fibre core is away from difference, in the first V-groove and the second V-groove on being put into substrate 2, can be ranked up under the microscope,
Next step operation is carried out again after ensureing optical fiber in groove, then using optical fiber fixed bonding agent 6, by the first optical fiber 4 and the second light
Fine 5, first V-groove and the second V-groove and cover plate 1 assemble, and then each and every one several components will be compressed above using fixation pressure,
Ensure that optical fiber contacts with the both sides in the first V-groove and the second V-groove and cover plate 1, so that it is guaranteed that all fiber cores are same
On one horizontal plane, solidification then is exposed to optical fiber fixed bonding agent 6 using uviol lamp.After solidification terminates, in the first V-groove
The first optical fiber 4 and the second optical fiber 5 are protected with point bare fibre Protection glue 3 at the afterbody bare fibre of the second V-groove respective layer.
After glue is fully cured, exiting surface is polished to by 8 ° of angles or other angles, polishing process by appropriate abrasive polishing process
In need to ensure optical fiber lapping amount, ensure signal transmission quality.
By embodiment as can be seen that for a kind of more diameter optical fibers it is non-equidistantly fiber array scheme fibre core away from d1 with
D2 can be modified according to demand, and the polishing angle of end face and cover plate can be changed according to product usage scenario, such as
Fig. 4 is a certain derivative class end face product.Therefore expansibility of the present utility model is advantageously in the popularization and application of product.Together
When specification and drawings be regarded in an illustrative, rather than a restrictive.
