Abstract
The utility model provides a V-shaped groove base plate used for the multi-fiber joint. The utility model comprises a base plate main body; a plurality of V-shaped grooves which are used to put the optical fiber is arranged on the surface of the base plate main body; a V-shaped groove which is used to put the positioning pin is arranged on the surface of the base plate main body at the outer side of the V-shaped groove positioned at the two sides. The V-shaped groove base plate is convenient to enhance the precision during manufacture, and to ensure that the optical fiber position is more precise and reliable, the communication loss can be reduced, and the communication quality can be enhanced.
Description
Technical field
The utility model relates to a kind of substrate that is used for how fine joint.
Background technology
In recent years, use in a large number based on high speed and high-capacity optical fiber communication system such as dense wave division multipurpose (DWDM), fibre-optical splice is an important component part of DWDM technology.Though adopt the joints such as SC of single fiber in the past widely, but the raising that the growth of requirement of how fine high density joint and joint merging precision is required along with dwdm system in recent years, traditional single fiber joint technology can't satisfy existing market demands.In Japan, the density of optic fibre of 8 most popular core multifiber connectors is up to 5 times of the SC connector.
The method of die formings is used in many fine joint manufacturings, relies on to lay pin in the mould and form the positioning optical waveguides on the how fine connector substrate and the hole of register pin.Thereby the position that can change pin makes the easy off-design requirement of formed pilot hole on the how fine connector substrate because fluid flows in mould, the skew of position when causing fiber alignment and cause the insertion loss; In addition, with hole positioning optical waveguides and register pin, the inevitable outer warp greater than optical fiber and register pin in its aperture causes optical fiber and register pin accurately to locate, and also can cause bigger insertion loss.In addition, the material that uses during mould molding is engineering plastics, and for improving performance, present way is to add silica flour in plastics, but the physical properties such as thermal expansivity of this composite material and fiber optic materials differ greatly, and make the loss of how fine joint be subjected to environmental change and bigger fluctuation is arranged.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of manufacturing and the high V-type groove substrate that is used for how fine joint of fiber orientation precision.For this reason, the utility model by the following technical solutions: it comprises substrate body; The substrate body surface is provided with some for the V-type groove of placing optical fiber; In the outside of the aforementioned V-type groove that is in both sides, described basic body surface is provided with the V-type groove of placement positioning pin.Owing to adopt the technical solution of the utility model, be convenient to improve precision during fabrication, and make fiber orientation more accurate and reliable, reduce the communication loss, improve communication quality.
