Abstract
A ferrule (4) according to the invention for an optical fiber (1)is characterised in that the ferrule (4) is produced from plastics material and is welded on the optical fiber (1), which also consists of plastics material, preferably by ultrasound. The cladding (2) of the optical fiber (1) comprises depressions (3) which on welding also produce an interlocking fit in addition to the material connection.
Claims16
A process for fastening a ferrule on an optical fiber, comprising the steps of:
- axial stripping a portion of cladding from one end of an optical fiber
- slipping the ferrule over the stripped region of the optical fiber such that the ferrule does not protrude into or deform the optical fiber;
- and
- welding a contact region of said ferrule to said stripped region.
1 more element
A cable assembly comprising:
- a ferrule comprising a plastics material;
- an optical fiber comprising a cladding, a core, an end, and a stripped region around said end, a portion of said cladding being removed from said stripped region, said stripped region being welded to said ferrule, said ferrule not protruding into or deforming said fiber.
