So number, and 1≤M≤64, N are natural number, and 2≤N≤64, chip of light waveguide are located at the rear side in box body, every input light
Fine and every output end optical fiber is naked fibre obtained from removing after respective coating, every input end fiber, every
Be cased with a protection sleeve pipe outside output end optical fiber, every input end fiber, every output end optical fiber respectively with corresponding protective case
Leave gap between pipe, adapter is positioned at the front side of box body by grafting form, every input end fiber of setting, every it is defeated
It is interior, every input end fiber of setting, every output end light close to the side of chip of light waveguide to go out to hold optical fiber, each adapter
Fine, each side of the adapter away from chip of light waveguide be it is outer, the both ends of chip of light waveguide respectively with M roots input end fiber and N
The inner coupling package of root output end optical fiber, to realize M × N number of branch on chip of light waveguide, every input end fiber, every
The outer end of output end optical fiber is connected to a connector, and each connector inserts the inner side of an adapter, the M roots input
End optical fiber, N root output ends optical fiber, the protection sleeve pipe of M+N root same sizes, M+N connector are in box body.
External equipment must use the connector that can be inserted on the outside of adapter when being docked with the shunt, and the connector and
Connector in the shunt will be adapted in type, could form the connection of light-path, realize the shunt and external equipment
Connection.
Used in the connector and external equipment connect for the outer end of every input end fiber, every output end optical fiber
For connector, the optical property (such as insertion loss, return loss index) when each connector uses depend on it is many because
Element, including：Optical fiber optical property in itself and physical index are (such as：Concentricity between fibre core and covering)；Each connection
The accuracy of manufacture (concentricity of the quality of finish of such as its end face, its endoporus and outer wall) of contact pin in device；Each connector with
Merging precision (concentricity of the covering of corresponding optical fiber and the endoporus of contact pin and match stress degree) between corresponding optical fiber.
It can be seen that the shunt employs the connecting structure that the poor connector of reliability is engaged with adapter, reduce
The reliability of optical transmission system, manufacturing cost are also higher.
In addition, referring to Fig. 1, existing hard-pressed bale type optical fiber X include the inside and outside fibre core X1 being coaxially socketed, covering X2, coat X3,
Coating X4.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of higher planar optical waveguide work(of optical transport reliability
Rate shunt.
In order to solve the above technical problems, the invention provides a kind of planar optical waveguide power splitter, including box body, light wave
Chip, M roots input end fiber, N root output ends optical fiber, M+N root protection sleeve pipes are led, M is natural number, and 1≤M≤64, N are nature
Number, and 2≤N≤64, chip of light waveguide are located at the rear side in box body, covered outside every input end fiber, every output end optical fiber
There is a protection sleeve pipe, every input end fiber of setting, every output end optical fiber, every protection sleeve pipe are close to chip of light waveguide

Core is injury-free, and can effectively stablize fibre core during fusing operation, both facilitates welding, effectively increases welding quality again.
The inner of the every protection sleeve pipe is put in box body, the distance of the inner of every protection sleeve pipe on front side of box body
For 1-2cm.
After the structure, first, the inner side of every protection sleeve pipe can obtain preferable positioning on front side of box body；Second,
It is also more square when every input end fiber, every output end optical fiber fill insulating cement between corresponding protection sleeve pipe the inner respectively
Just it is, easily operated.
Described insulating cement is fast dry type insulating cement.
So, every input end fiber, every output end optical fiber can be achieved respectively between corresponding protection sleeve pipe the inner
It is quick fixed, insulate after adhesive curing, there is certain elasticity so that workmen will not break in fiber stripping, pull fibre core.
The length of the fiber core part is 4-5cm, and fiber core part is respectively in fore-and-aft direction between the inner of corresponding protection sleeve pipe
On leave 2-5cm distance；
The every output end optical fiber is located at the corresponding optical fiber span length in box body, it is sufficient to so that corresponding fiber segment is with box body
Inwall is constraint and generally round or large semi-circular arrangement.
The length of the fiber core part and its respectively between corresponding protection sleeve pipe the inner fore-and-aft direction distance so that every
Input end fiber, every output end optical fiber between respective fiber core part and the respective end of chip of light waveguide by being easily achieved
Coupling package；
Above-mentioned corresponding fiber segment is arranged by constraint and generally round or large semi-circular of inboard wall of cartridge so that every output
Optical fiber bending within reason in box body is held, can effectively protect every output end optical fiber.
The outer end of the every input end fiber and every output end optical fiber exceeds the distance of corresponding protection sleeve pipe outer end
For 2-3cm.
After the structure, it is easy to the fusing operation of every input end fiber, every output end optical fiber and external equipment, has
