Abstract
Disclosed is a spliced joint between two fibers, in which at least one of the fibers includes a fiber core comprising at least one inner signaling core and a pumping core that surrounds the signaling core, and a fiber cladding which rests against the pumping core and is used for guiding light within the pumping core. The fiber cladding of the at least one fiber is removed at least in part in a radial direction in a connection zone extending from the spliced end of the fiber along a predetermined length in the longitudinal direction of the fiber. Furthermore, a supporting jacket may be provided, inside which the spliced ends of the two fibers are arranged and which extends along the entire connection zone and therebeyond. The supporting jacket may be mechanically connected to both fibers next to the connection zone while not being mechanically connected to and being at a distance from the respective fiber along the entire connection zone.
