A protective system for optical components, having a container, at least one optical component fixed inside said container and a length of optical fiber (F) which has a plastic coating, connected to said optical component. An optical feedthrough for said section of fiber is placed in a feedthrough hole in a wall of said container and hermetically fixed therein. The optical feedthrough has an elongate body which has a longitudinal feedthrough hole into which said optical fiber (F) can be placed and a portion of said length of fiber (F) being stripped of said coating. The said portion of fiber (F) which is stripped of coating is soldered to one end of said elongate body by means of a metallic solder, and this soldering, in the surface portion around said portion of fiber (F), is coated with a layer of a polymeric sealant.
