Abstract

The utility model discloses a kind of optical fiber branch device; also fiber optic protection sleeve pipe can be penetrated separately by with being separated between multifiber in the ribbon fiber of air tight structure in the finite space; optical fiber is calculated from initial separately to the bee-line be finally fixed on protective casing by the minimum bending radius not increasing fiber transmission attenuation; eliminate the beam splitting box of existing fiber splitter, be applicable to multichannel optical fiber transmission and optical information processing inside modules be connected with light path between outside.Use of the present utility model can overcome the shortcomings such as art methods is high to the cost connecting light path and run into, volume large, optical path length, troublesome poeration and technological problems point is many, has the advantages such as cost is low, volume is little, method is simple.

Description

A kind of miniaturized multichannel hermetic fiber splitter

Technical field

The utility model relates to a kind of miniaturized multichannel hermetic fiber splitter.The utility model can in very little volume; in an orderly manner ribbon fiber is scatter and enter optical fiber protective casing and dock with connector; and do not increase original optic path loss; can access as the light path of light process and light delivery module or pick out device widely; be particularly useful for the light processing unit of batch productionization as optical wavelength selector switch WSS, volume is little, cost is low, efficiency is high.

Background technology

In the last few years, along with more and more higher to the requirement of optical transport information capacity, and more and more less to the restriction of light processing unit module volume, the number of channels of optical fiber branch device and needed for the volume that takies receive more concern.

Existing hyperchannel hermetic fiber splitter is processed as two unit optical fiber seal and fiber optic tap, extends required band fine length and cost is increased; Fiber optic tap structure as one independently unit appear on the not shielded band fibre of prolongation, make troubles to operation, and need other project organization to fix, occupy limited spatial accommodation further; Therefore existing hermetic fiber splitter takies that volume is large, cost is high and operation inconvenience.

Utility model content

The purpose of this utility model is to overcome above-mentioned defect, provides that a kind of volume is little, cost is low, structure simple hyperchannel hermetic fiber splitter.

To achieve these goals, the technical solution adopted in the utility model is as follows:

Miniaturized multichannel hermetic fiber splitter, comprise ribbon fiber and hermetically-sealed construction thereof, inside and outside two locating pieces and the locating support both connection, described positioned internal block is and ribbon fiber hermetically-sealed construction one, outside locating piece and box body are fixed together, ribbon fiber is dispersed into spatial light fibre array in the space between two locating pieces, and pierces into the array hole of outside locating piece.

Described ribbon fiber hermetically-sealed construction, positioned internal block and tray interior are fixed together by scolding tin, thus while realizing the sealing between ribbon fiber and box body, have also been fixed on box body by locating device.

The locating support of described connection positioned internal block and outside locating piece, its length depends on that the radius-of-curvature that fiber dispersion is opened is the minimum profile curvature radius not affecting Optical Fiber Transmission parameter.

Described outside locating piece, is fixed together by bolt arrangement and box body outer wall, and make whole splitter structure integrated with box body, the optical fiber of box portion outside is all subject to the protection of fiber optic protection sleeve pipe array.

The utility model compared with prior art, has the following advantages and beneficial effect:

(1) while ribbon fiber hermetically-sealed construction is fixed on box body by scolding tin, the positioned internal block of splitter also welds together with box body, while achieving and sealing between ribbon fiber and box body, also whole branched structure is securely fixed on box body.

(2) connect the locating support of positioned internal block and outside locating piece, its length can regulate, and guarantees that the distance between two locating pieces is the shortest.Due to the array format difference that the simple optical fiber number difference comprised in ribbon fiber becomes with optical fiber arrangement, the radius of fibre-optical bending is also different, causes can meet fibre-optical bending and do not bring the locating support shortest length of loss also different.

(3) outer wall of outside locating piece and box body is fixed together by bolt arrangement; the optical fiber array hole entered on outside locating piece just starts the protection being subject to fiber optic protection sleeve pipe; and the optical fiber extended to outside box body is all separate single state, there is not ribbon fiber outside box body.

Accompanying drawing explanation

Fig. 1 is inner structure schematic diagram of the present utility model.

Fig. 2 is schematic diagram outside the utility model.

In above-mentioned accompanying drawing, the name that Reference numeral is corresponding is called: 1-ribbon fiber, 2-ribbon fiber hermetically-sealed construction, 3-positioned internal block; 4-locating support, the outside locating piece of 5-, 6-fiber optic protection sleeve pipe array, 7-box body; 8-bolt arrangement, 9-viscose glue, 10-scolding tin, the silica gel protected circle of 11-.

Embodiment

Below in conjunction with embodiment and accompanying drawing thereof, the utility model is described further, but embodiment of the present utility model is not limited thereto.

Embodiment

As Fig. 1, shown in 2, miniaturized multichannel hermetic fiber splitter, comprise ribbon fiber 1, ribbon fiber hermetically-sealed construction 2, the positioned internal block 3 integrated with optical fiber seal structure 2, connect the locating support 4 between positioned internal block 3 and the outside locating piece 5 with porose array, for the protection of the fiber optic protection sleeve pipe array 6 of simple optical fiber, for carrying the box body 7 of positioned internal block 3 and outside locating piece 5, the bolt arrangement 8 of fixed outer locating piece 5 and box body, fiber optic protection sleeve pipe array 6 is fixed on the viscose glue 9 of outside locating piece 5, optical fiber seal structure 2 and positioned internal block 3 are fixed on the scolding tin 10 of box body 7.

In the utility model, ribbon fiber hermetically-sealed construction 2 is fixed on box body 7 by scolding tin 10, has also been fixed on box body 7 by the positioned internal block 3 of splitter simultaneously.

In the utility model, ribbon fiber 1 scatter along locating support 4 becomes spatial light fibre array, and enters the array hole of outside locating piece 5, starts the protection being subject to fiber optic protection sleeve pipe 6.

In the utility model, outside locating piece 5 is fixed together by bolt arrangement 8 with box body 7 outer wall, and in the outer race of fiber optic protection sleeve pipe array 6 silica gel protected circle 11.

According to above-described embodiment, the utility model can be realized well.
