A protective tube arrangement particularly useful for positioning the end of a glass fiber relative to an opto-electronic component of a module having a housing, which housing engages the protective tube characterized by the glass fiber being secured to the tube at two axially spaced locations with the length of the fiber extending between the two locations and the distance of the tube between the locations being selected so that the fiber has a greater length than the distance for all temperatures below a maximum temperature limit. Thus, the fiber is not subjected to tensile stresses and the distance between the two locations on the tube and the length of the fiber are selected so that the compressive stresses are below 1 N/mm2 for all temperature ranges between the maximum temperature limit and the minimum temperature limit. The method for securing the fiber in the tube can either be by forming both connections simultaneously or in sequence but forming them at a temperature greater than the maximum temperature limit so that after forming the connection and cooling to the maximum temperature limit or therebelow, the fiber between the two connecting locations will not be subjected to tensile stresses.
