METHOD AND A DEVICE FOR CONNECTING AN OPTICAL FIBRE WITH ANOTHER OPTICAL COMPONENT, FOR EXAMPLE ANOTHER OPTICAL FIBRE

摘要

ABSTRACT OF THE DISCLOSUREThe present invention provides a method for connectingan end portion of an optical fibre with another optical component,for example another optical fibre, wherein the end portion of theoptical fibre is positioned and fixed in a sleeve element byaxially displacing at least three centering elements, which arepositioned between the surface of the end portion of the opticalfibre and a surface portion, which encloses the end portion ofthe optical fibre and tapers in the axial direction of the sleeveelement, said surface portion preferably being conical, in rela-tion to the sleeve element to engagement with the surface of thefibre end portion as well as with said tapering surface portionand the sleeve element with the fibre end portion fixed thereinand the other optical component are positioned in a coupling devicewith the optical fibre and the other optical component in opticalconnection with each other, characterized in that the end portionof the optical fibre by said positioning and fixing in the sleeveelement is provided in an exactly predetermined position in rela-tion to an outer reference surface of the sleeve element and thatthe end surface of the fibre end portion fixed in the sleeve por-tion is positioned in a correct connection position in relationto the other optical component by positioning the reference surfaceof the sleeve element in engagement with guiding surfaces in thecoupling device.
