Abstract

An optical cable includes an optical fiber having a fiber core and a fiber cladding, and an output coupling plug at an output coupling-side fiber end of the optical fiber. The output coupling plug comprises at least one cladding light sensor arranged behind the output coupling-side fiber end and configured to measure cladding light that exits frontally from the fiber cladding at the output coupling-side fiber end.
