Method of and device for measuring return losses in optical fibre components
摘要
A method and device are provided for measuring return losses in optical fibre components, wherein the radiation reflected by the optical fibre component (17) is reintroduced into the cavity of the source (11) and the value of such losses is obtained by measuring the amplitude of the radiation resulting from the combination between such reflected radiation and the radiation generated by the source (11). <IMAGE>
