Abstract

An optical fiber unit includes an optical fiber. The optical fiber includes a light guiding region configured for guiding light through the optical fiber, an input coupling end having a first fiber end surface for coupling the light into the light guiding region, and an output coupling end having a second fiber end surface for coupling the light out of the light guiding region. The optical fiber unit further includes a first end piece arranged at one of the input coupling end and the output coupling end. The first end piece is configured to couple the light into the light guiding region or couple the light out of the light guiding region. The first end piece includes a reflection element configured to divert a portion of the light propagating along a direction of propagation through the light guiding region away from the direction of propagation.
