Description
Technical field
This utility model belongs to capillary for fixing optical fiber field, is specifically related to the double cilium tubule of a kind of single hole.
Background technology
It is known that in the case of the optical axis regulation of mental activities of the opticses such as relative optical-waveguide-type element fixes optical fiber, use and be formed with the capillary for fixing optical fiber (following, also referred to as capillary glass tube) inserting hole inserting fixing optical fiber.This capillary glass tube serial shape in the way of in the state of the optical axis of the central shaft and optics correctly positioning this insertion hole is fixed on the end face of optics, in this case, generally, optics and capillary glass tube are both arranged on the same plane of substrate (or housing or retainer).
As its concrete example, patent documentation: Unexamined Patent 2-236508 publication discloses following situation: by the optical waveguide components of cross section circular and the lasso of the cross section circular keeping optical fiber, the end face making both in the endoporus at single sleeve is chimeric in the way of being engaged with each other to be kept, and the optical fiber forming lasso on the position from the center of this lasso deviation (eccentric) inserts fixing insertion hole.Although the hole of inserting of lasso deviate from the amount that the offset of core with optical waveguide components is corresponding from the center of lasso, but the outside of lasso is of a generally circular or rounded, and does not have planar portions.Therefore, described in the situation of patent documentation described above, if the bonding end face of optical waveguide components is rectangle or substantially rectangular, then on the bond area guaranteeing lasso and optical waveguide components and carry out producing worst fatal problem in the regulation of mental activities operation of optical waveguide components.
Utility model content
Utility model purpose: in order to solve the deficiencies in the prior art, this utility model provides the double cilium tubule of a kind of single hole.
Technical scheme: the double cilium tubule of a kind of single hole, including capillary body, described capillary body is provided with the one channel that can be inserted into double optical fiber, described one channel is made up of straight pipeline and the through connection of long trumpet mouth pipeline, described pair of optical fiber inserts side by side, the diameter of optical fiber is 0.125mm, the hatch bore diameter size of described long trumpet mouth pipeline is 0.7 mm-0.9mm, the opening angle of described long trumpet mouth pipeline is 6 °, the length scale of described long trumpet mouth pipeline is 3.0 mm-4.0 mm, described pair of optical fiber is provided with covering, the cementing depth requirements in capillary body of described covering is ＞ 0.5mm.
