Abstract
A method and apparatus for the manufacture of optical transmission elements comprising a bundle of at least one light waveguide lead having a coating of filling material and receiving an outer envelope, characterized by the method, including applying a first coating of filling material to the bundle, stripping a portion of the material from the coated bundle, applying a second coating and then, subsequently applying the envelope. By stripping a portion of the first coating of filling compound or material, air or gas bubbles in the filling compound will be stripped from the coated bundle and reduce the chance of damage to the light waveguide leads.
