Optisk fiberkabel samt sätt att överföra laserljus med höga effekter

摘要

An optical fibre cable comprises a fibre having a core (4) and a surrounding cladding (9). At least one of the contact ends of the core (4) is provided with a rod (1) of larger diameter than the core. At this end, the fibre has a reflector (7) designed to conduct rays entering outside the fibre towards an area (6) where they can be absorbed without causing any damage, the rod (1) being so designed that rays not linked into the fibre are conducted towards the reflector (7). A method for transmitting light by using the optical fibre cable is also disclosed.
