METHOD FOR IDENTIFYING AN OPTICAL TRANSMISSION MEDIUM, APPARATUS FOR IDENTIFYING THE SAME AND METHOD FOR OPTICAL TELECOMMUNICATION

In a method of identifying an optical transmission medium from a plurality of such media, the particular medium to be identified is excited by polarized light which is modulated at the identification location (by applying either an electromagnetic action or a mechanical action) so that the medium ca...

Zusammenfassung:In a method of identifying an optical transmission medium from a plurality of such media, the particular medium to be identified is excited by polarized light which is modulated at the identification location (by applying either an electromagnetic action or a mechanical action) so that the medium can be identified by the deviation of the plane of polarization of the transmitted light.
