Abstract

The invention relates to the accouplement of the fiber replicator insulators (11) which enable the red laser connection and also protect the system components by guiding the retro-reflecting laser beam (17) in a separate line, during cutting and which measures the retro reflection intensity, to fiber laser modules (100).
