Background technology

Existing in EPON employed PLC type planar optical waveguide optical power divider, as Chinese utility model patent ZL200820095910.2, name is called the disclosed a kind of structure of 128 road light output PLC type optical power divider, it comprises the single fiber fiber array, with fine fiber array and at described single fiber fiber array with the optical power divider chip between the fine fiber array, the input end of described optical power divider chip and output terminal respectively with described single fiber fiber array, be with fine fiber array optocoupler merga pass UV glue to fixedly connected.Fiber array and the optically-coupled of optical power divider chip location process is as follows: the optical power divider chip is fixed on the chip set in the coupling table; The 6 DOF that the single fiber fiber array is fixed on coupling table one side is adjusted on the platform; By the position between 6 DOF adjustment axial adjustment single fiber fiber array and the chip input end; The optic fibre input end of single fiber fiber array is connected on the white light source, and reflective mirror is placed on the 6 DOF adjustment platform of coupling table opposite side, fine tuning single fiber fiber array position, brighter and brightness is connected to single fiber on the light source of Gui Haoling after consistent up to the hot spot on the catoptron; Take off reflective mirror, to be with fine fiber array to be fixed on the coupling table, to be connected to above the light power meter with two optical fiber of outermost of fine fiber array simultaneously, loss to passage is monitored, use the position of sextuple adjustment rack fine setting with fine fiber array, only the loss of institute's monitoring channel is within the limits prescribed to the light power meter; The sextuple axle of adjusting in fine setting both sides, UV glue on point between fiber array and the chip is adjusted the fiber array position, in acceptability limit is transferred in loss; The probe of UV light source machine is moved on to the top, some glue position of coupled apparatus, open the UV point gum machine UV glue is cured; After the curing device shifted out and finish assembly work.

This shows, the PLC type planar optical waveguide optical power divider of this structure, because the relative position between fiber array and the optical power divider chip is uncertain, both optically-coupled need just can finish by above-mentioned complexity, loaded down with trivial details operation, therefore, this shunt manufacturing procedure complexity of one side, difficulty of processing is big, production efficiency is low, this shunt is in process on the other hand, and is very high to operating personnel's requirement, very easily causes product rejection when misoperation, therefore yield rate is low, and processing cost is higher.

The utility model content

It is easy that the technical problems to be solved in the utility model provides a kind of processing, production efficiency and yield rate height, good reliability, a kind of PLC type planar optical waveguide optical power divider that processing cost is lower.

For solving the problems of the technologies described above, the utility model adopts so a kind of PLC type planar optical waveguide optical power divider, comprise first fiber array, second fiber array and be positioned at described first, optical power divider chip between second fiber array, the input end of described optical power divider chip and output terminal are respectively with described first, the second fiber array optically-coupled, between the input end of described first fiber array and described optical power divider chip, be provided with input end optically-coupled locating device, between the output terminal of described second fiber array and described optical power divider chip, be provided with output terminal optically-coupled locating device.

Described input end optically-coupled locating device preferably is arranged on two register pins on described first fiber array and is arranged on two pilot holes that cooperatively interact with described two register pins on the described optical power divider chip input end by the space certain distance and constitutes; Described output terminal optically-coupled locating device preferably is arranged on two register pins on described second fiber array and is arranged on two pilot holes that cooperatively interact with described two register pins on the described optical power divider chip output by the space certain distance and constitutes.

Described first fiber array can be the single fiber fiber array, and described second fiber array can be is with fine fiber array.

After adopting such structure, because input end optically-coupled locating device is set between the input end of first fiber array and optical power divider chip, this locating device preferably is made of two register pins that cooperatively interact and pilot hole; Output terminal optically-coupled locating device is set between the output terminal of second fiber array and optical power divider chip, and this locating device preferably is made of two register pins that cooperatively interact and pilot hole; Therefore, adding man-hour, only need two register pins on first fiber array are inserted in two pilot holes of chip input end, two register pins on second fiber array are inserted in two pilot holes of chip output, can realize the optically-coupled between first, second fiber array and the optical power divider chip.Thereby the utility model is compared with existing PLC type planar optical waveguide optical power divider, the utility model need not can realize fiber array and the optically-coupled of optical power divider chip by complicated procedures of forming, process easy, production efficiency and yield rate have been improved greatly, and product reliability is good, and processing cost is lower.
