Abstract
An optical amplifier having a doped fluoride glass optical fiber and a process for producing such an amplifier. To produce the doped fluoride glass fiber amplifier which is operable to amplify a light signal (S), an optical multiplexer (4) is produced having on the one hand two silica fibres (6, 8) and on the other a fluoride glass fiber (2), whereof at least one section is doped and an optical coupling is brought about between the fluoride glass fiber and at least one other silica fibre (12, 14).
