Embodiment
As Figure 1-Figure 4, the double fiber array of a kind of individual layer, including installing plate 1, cover plate 2 and some are mutually
The spaced optical fiber 7 of first optical fiber 3 and second, the upper surface of installing plate 1 are provided with several mounting grooves being parallel to each other
4, first optical fiber 3, the second optical fiber 7 are arranged in mounting groove 4 after removing coat, and before the first optical fiber 3, the second optical fiber 7
After misplace, the cover plate 2 is fastened on the upper surface of installing plate 1 for the first optical fiber 3, the second optical fiber 7 are fixed on into mounting groove 4
It is interior.First optical fiber 3, the front-back staggered of the second optical fiber 7 are set, being capable of interactional area between the first optical fiber 3 and the second optical fiber 7
Domain is smaller, the crosstalk being effectively reduced between receiving and transmitting signal, meanwhile, the first optical fiber 3, the front-back staggered of the second optical fiber 7 set meeting
Directly result in distance between VCSEL chips and PD chips and become big, be easy to radiate, the present invention can be adapted to low channel transfer, it is also possible to
To be transmitted in high channel, the transmitting of such as 12 tunnels, 12 tunnels receive, and the number of mounting groove 4 is typically four, eight, 12,20 fourth class,
In the present invention, the first optical fiber 3 can be reception optical fiber or launching fiber；Second optical fiber 7 can be launching fiber,
It can also be reception optical fiber.
The mounting groove 4 is V-groove, U-type groove or rectangular channel, in order to the first optical fiber 3, the placement of the second optical fiber 7 and solid
It is fixed, make the first optical fiber 3, the second optical fiber 7 be less likely to occur to move.
First optical fiber 3, the cutting angle A of front end surface of the second optical fiber 7 are more than 40 ° and less than 50 °.Cutting angle
A is easy to the reflection of light, and can reduce the loss of light energy.
The cover plate 2 is glass cover-plate, and the installing plate 1 is glass mounting plates 1.
At least one groove 5 is provided with the upper surface of installing plate 1 for avoid the first optical fiber 3, the second optical fiber 7 by
Backfin is broken.
Present invention additionally comprises fibre-optical splice 6, rear end of the fibre-optical splice 6 with the first optical fiber 3, the second optical fiber 7 passes through
Glue is fixedly connected.In the present invention, fibre-optical splice 6 is conventional MT multi-pin connectors, and in the prior art, fiber array and MT are more
There is short section of optical fiber exposed between core plug, be flexible coupling equivalent to one kind, use the exposed mode that is flexible coupling of optical fiber, a side
Face overall dimensions are larger, are unfavorable for the small-sized encapsulated of optical module, while in actual manufacturing process, the length of optical fiber is difficult to essence
Really control, but inside optical module, its position dimension is fixed, as optical fiber is partially short, then can not be installed FA-MT components
Enter in module, conversely, as optical fiber is long, but optical fiber is always in overbending by stress state, or even can not install, this programme
Using hardwired integral structure scheme, i.e. fiber array and fibre-optical splice 6 is bonded to one, overall compacter compact, leads to
Chang Changdu only has the half of prior art, because length easily accurately controls, is more suitable for bulk production, and optical fiber is not present
State in bending by stress so that the long-term reliability of product is higher.
The assemble flow of the present invention is as follows：
The coat of the first optical fiber 3 cut, the front end of the second optical fiber 7 is divested, then by the first optical fiber 3, the second light
The front end surface grinding and polishing angle at 45 ° of fibre 7；
First optical fiber 3 is put into mounting groove 4, the front end surface in 45° angle of the first optical fiber 3 will be toward the front end of installing plate 1
Direction it is exposed, in the drive end bearing bracket upper cover plate 2 of installing plate 1, and compress, the first optical fiber 3 is closely pressed into mounting groove 4；
Second optical fiber 7 is put into mounting groove 4, the front end surface in 45° angle of the second optical fiber 7 wants exposed and is located at groove
5 tops, the second optical fiber 7 misplace with the first optical fiber 3, in the rear end cap upper cover plate 2 of installing plate 1, and compressed, and make the second optical fiber 7 tight
It is close to be pressed into mounting groove 4；
Ultraviolet cured adhesive water is injected between mounting groove 4 and cover plate 2, then solidified glue under ultraviolet light, then high temperature adds
Heat baking is so that glue is fully cured；
The coat of the array of the first optical fiber 3, the array rear end of the second optical fiber 7 is divested respectively, and cleaned；
The array of the first optical fiber of coat 3 will be divested, the array rear end of the second optical fiber 7 staggeredly penetrates corresponding fibre-optical splice 6
Hole in；
The relative position of two layers of fiber array before and after adjustment, the rear end end face and fibre-optical splice 6 for making mounting groove 4 are close to one
Rise；
Heat cure glue is filled by the injecting glue window of fibre-optical splice 6, allows glue to flow naturally, fills fibre-optical splice 6
Space between optic fibre hole and fiber array and fibre-optical splice 6, then heat and glue is fully cured, just by two row's fiber arrays
And fibre-optical splice 6 is bonded to one.
The end face of fibre-optical splice 6 on request grinding and polishing into needs angle, such as 0 degree, 8 degree etc..
The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to above-mentioned embodiment, as long as with
Essentially identical means realize that the technical scheme of the object of the invention is belonged within protection scope of the present invention.
