ABSTRACT:
A soft polymeric clad glass fiber waveguide with an easy to handle, low-loss end termination is disclosed. Each end termination is formed with a pair of telescopically assembled plastic sleeves. The inner sleeve is heat bondable to the glass core and has a refractive index lower than the glass core. It replaces an end portion of the soft rubbery polymeric cladding. The outer sleeve is heat shrinkable and during the termination procedure functions to compress, center and confine the inner sleeve. After termination, it functions to stiffen the fiber end and strain relieve the junction between the soft polymeric cladding and the stiffer inner sleeve. A method for making such a waveguide termination is disclosed. Also disclosed is an environmentally sealed optical waveguide of related construction.
