ABSTRACT:
An optical fiber comprises a hollow fiber core, wherein the front faces of both fiber ends of the hollow fiber core are open and each fiber end is surrounded by a protection element in a dustproof fashion. The protection element includes a window at its front face in front of the fiber end to couple and decouple light to and from the hollow fiber core.
