PROCEDIMENTO E APPARECCHIATURA PER LA MISURA DELLA DISPERSIONE DELLAPOLARIZZAZIONE IN FIBRE OTTICHE.

摘要

The process and apparatus to enable measurement of polarization dispersion of a single-mode optical fibre by launching measurement light at one end of the fibre and analyzing polarization of the light reflected by the other end and collected at such launch end. Optical or electronic masking of light reflected by the near end of the fibre is performed during launch.
