Embodiment 1:
Referring to Fig. 1, the mounting structure of existing single-core fiber include V-groove 1, the single-core fiber being set in V-groove 13 with
And lid closes the cover board 2 in 1 notch of V-groove.
Before cover board 2 is installed, it is necessary first to single-core fiber 3 is placed in V-groove 1, due to gravity, single light
Fibre 3 can be automatically scrolled to the bottom of V-groove 1, so that single-core fiber 3 is supported on the two sides side wall of V-groove 1 simultaneously, by
In single-core fiber 3 shape be high degree of symmetry cylinder, no matter therefore left-handed or dextrorotation single-core fiber 3, single-core fiber 3 exist
Lethal affect will not all occur for the position in V-groove 1.Cover board 2 is covered at 1 notch of V-groove later, and with photoresist to lid
Plate 2 is fixed, while being positioned using cover board 2 to single-core fiber 3, and single-core fiber 3 can still turn in V-groove 1
It is dynamic.
Embodiment 2:
Referring to fig. 2-6, embodiment shows the mounting structure of multi-core optical fiber array, including V-groove 1, it is set to V-groove
Multi-core optical fiber 4 and lid in 1 close the cover board 2 in 1 notch of V-groove, and multi-core optical fiber 4 is pressed on V-groove 1 by cover board 2 simultaneously
Two sides inner wall on.Multi-core optical fiber 4 due to cross sectional shape be non-centrosymmetry figure, multi-core optical fiber 4 in V-groove 1 not
It may in the presence of rotation.
Before cover board 2 is installed, multi-core optical fiber 4 is placed into V-groove 1, multi-core optical fiber 4 can be because of self gravitation effect
It is automatically supported on the two sides inner wall of V-groove 1, the two sides inner wall for ultimately forming V-groove 1 is respectively to the support force of multi-core optical fiber 4
F1And F2, frictional force is respectively F1μAnd F2μ, F1、F2、F1μAnd F2μReach equilibrium state with the gravity of multi-core optical fiber 4.Multicore at this time
Angle in optical fiber 4 where all fibre cores between planes and horizontal plane isCover board 2 is pushed later, so that cover board 2 is to multi-core optical
The highest point of fibre 4 applies pressure F straight down0, pass through pressure F0Multi-core optical fiber 4 is driven to rotate in V-groove 1, so thatIt is reduced to 0 ° as far as possible, by pushing this means of cover board 2The attainable minimum value of instituteAs optical fiber imbalance angle,The levelness of smaller corresponding multi-core optical fiber 4 is better, by photoresist that cover board 2 is fixed again later, at this time multi-core optical fiber 4
It has been fixed in V-groove 1 together.
Which kind of specifically influenced by parameterIt does not know, the present embodiment is attempted through different V-grooves 1 to same thus
The multi-core optical fiber 4 of specification carries out installation experiment, right to probe into V-groove 1Influence, in order to reduce variable, in the present embodiment
V-groove 1 be all made of symmetrical structure, studied by the V-groove 1 of different angle of releases.Since V-groove 1 is needed to multi-core optical fiber 4
It is positioned, if the angle of release of V-groove 1 is too small, multi-core optical fiber 4 possibly can not be filled in V-groove 1, so the minimum of V-groove 1
Angle of release is set as 40 °.
When angle of release be 40 °,It is 1.8 °, as angle of release is gradually increased,It is gradually reduced, when angle of release is 120 °,Only have 0.7 °, has met the levelness demand of practical multi-core optical fiber 4.Between 40 ° and 60 ° of angle of releaseDifference be up to
Between 0.5 °, 60 ° and 80 ° of angle of releaseDifference drop between 0.3 °, 80 ° and 100 ° of angle of releaseDifference drop to
0.2 °, and between 100 ° and 120 ° of angle of releaseDifference drop to 0.1 °, it follows thatMinimum be just slightly below
0.7 ° or so.In other words, angle of release influencesIt and is non-linear negative correlation.Furthermore before angle of release reaches 180 °,Pole
Small value difference seldom can reach, simultaneouslyMinimum not 0 deg.Situation excessive in view of angle of release simultaneously, the shortage pair of V-groove 1
The positioning action of multi-core optical fiber 4, in conjunction with above-mentioned experimental result, the angle of release optimal value of V-groove is 100 ° -120 °, in contrast light
Fibre imbalance angle is 0.7-0.8 degree.
Further, since the rotation process of multi-core optical fiber 4 involved in 2 pushing process of cover board, corresponding affects on 4 He of multi-core optical fiber
Friction coefficient μ between 1 inner wall of V-groove, μ is smaller, the easier rotation of corresponding multi-core optical fiber 4.It is being covered for multi-core optical fiber 4
Plate 2 push before between horizontal plane angle,Cover board 2 is difficult to so that multi-core optical fiber 4 rotates, thus solid in the case where excessive
In the case where determining angle of release θ and friction coefficient μ,The maximum value of permission isAlso directed to different included angles in the present embodiment
Lower different coefficients of frictionIt is studied.It is learnt by experiment, in the case where same θ value, μ is smaller correspondingMore
Greatly, corresponding cover board 2 is stronger to the regulating power of multi-core optical fiber 4.In the case of same μ value, θ value is biggerIt is bigger, i.e., big angle of release
V-groove 1 make multi-core optical fiber 4 have bigger adjustable range.
By taking μ=0.3 as an example,Increase within the scope of 55 ° -75 ° of θ in near-linear, and at θ=75 °With
The growth rate that θ increases is decreased obviously, but θ is within the scope of 75 ° -112 °Still it is linear increase with θ, and exists in θ
Between 112 ° -120 °,Linearly increase with θ, but growth rate is compared θ and slightly increased within the scope of 75 ° -112 °.Other
θ-in the case of μ valueThere is above-mentioned two inflection point, and increase with μ value, two inflection points gradually move to right, it can be seen that μ
With θ in addition to individually influencingExcept, between there is also cross influences, in other words μ and θ is smaller, and cover board 2 is to multi-core optical fiber 4
Adjustable extent it is bigger.
When additionally can see μ=0.5 in figure, θ is within the scope of 100 ° -108 °It is 0 °, therefore almost without tune
Energy saving power.In the case of the optimal value of θ is 100 ° -120 ° thus, μ value range is 0-0.45.If when certain μ=0.5, θ value
It is 108 ° -120 °.Further reduce if further increasing μ and being larger than the optimal value range of 0.5, θ, or even without optimal value model
It encloses.
In addition, in order to reduce μ value, the side wall that multi-core optical fiber 4 and 1 inner wall of V-groove squeeze is cambered surface.It is more in order to be promoted simultaneously
Symmetry when core fibre 4 rotates, multi-core optical fiber 4 are chosen for double D-type optical fibers, and corresponding cambered surface is arc surface, to promote multi-core optical
The symmetry that fibre 4 is adjusted.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, is familiar with
The those skilled in the art should be understood that the present invention includes but is not limited to attached drawing and interior described in specific embodiment above
