  • Process for aligning an optical fiber forming part of an optical transmission cable with an opto-electronic component, an adapter, and a coupling head comprising use of the process
    Patent number: 4456334
    Abstract: A process allowing the centering of an optical fiber in an opto-electronic head or the fiber-holder of a head in an adapter between the head and optical cable. To this effect, a certain clearance is left between the cover of the head and the main part of the fiber-holder. Then a tool is used having micrometric screws for producing permanent deformations on the periphery of the cover made from a ductile alloy, while checking the result by "dynamically" effected measurements. In the case of a fiber-holder in an adapter, a certain clearance is left between the end of the fiber-holder on the cable side and the adapter is provided with a skirt made from a ductile alloy which is deformed at certain points in a manner similar to that of the first case.
