Description
Technical field
This practicality relates to a kind of optical fiber communication network device, and more particularly, it relates to a kind of light wavelength division multiplexing.
Background technology
Assembly method when making the fiber optic network communication element adopts UV (ultraviolet photo-curing) epoxy cement usually, reinforces (as Fig. 2) with high-temp epoxy then.Or, add the bonding method of bonding agent (as Fig. 3) with the glass tube connection.Use the UV epoxy cement, there is following shortcoming in the method for reinforcing with high-temp epoxy then: seam ruptures easily, moistureproof ability, manufacturing process complexity.Connect with glass tube, it is bonding firmly to add the bonding method seam of bonding agent, easy fracture not, and moistureproof ability is strong, and manufacturing process is simple.But there is following shortcoming: the reason that has 8 degree oblique angles owing to the xsect of lens and glass capillary, after light path is adjusted, the axle center of lens and glass capillary is not on same straight line, therefore as connect glass tube that bridge uses axially also just can not be with lens and glass capillary axial consistent, produced an angle, so the internal diameter of glass tube is very big, could overlap.The bonding agent that is filled into glass tube like this is just inhomogeneous, and the temperature characterisitic of product is caused harmful effect, and the product after baking box is aging is easy to generate and inserts the phenomenon that loss increases, and yield rate is reduced.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned two kinds of existing shortcomings of production method, provide a kind of bonding firmly, easy fracture not, moistureproof ability is strong, good temp characteristic, manufacturing process is simple, realizes the light wavelength division multiplexing of automated production easily.
The purpose of this utility model is to be achieved by following technical scheme.
Light wavelength division multiplexing of the present utility model, mainly form by glass capillary, lens, optical filter, glass tube, housing, the glass capillary internal fixation has at least one optical fiber, is connected with glass capillary 1, glass tube 6, glass tube 7, glass tube 8, glass tube 9, glass capillary 5 in the described housing 13 from left to right in turn; Glass tube 6 is bonded on the right-hand member outside surface of glass capillary 1, is provided with lens 2 and optical filter 3 in glass tube 7, and the right-hand member of lens 2 is connected with the left end of optical filter 3; In glass tube 8, be provided with lens 4; Glass tube 9 is bonded on the outside surface of left end of glass capillary 5; One slit is arranged between the left end of the right-hand member of glass capillary 1 and lens 2, between the left end of the right-hand member of optical filter 3 and lens 4 slit is arranged, between the left end of the right-hand member of lens 4 and glass capillary 5, a slit is arranged.
Light wavelength division multiplexing of the present utility model has the angle distortion owing to connect bridge, adjusts the insertion loss of light wave easily, and have bonding firmly, easy fracture not, moistureproof ability is strong, good temp characteristic, manufacturing process is simple, realizes the advantage of automated production easily.
