Abstract

Apparatus for measuring characteristics of an optical fiber (11), at different positions along the length of the optical fiber (11), which apparatus comprises: tuneable source means (2) for providing optical pulses of light (3) which have a variable wavelength and a narrow wavelength bandwidth; polarisation selecting coupler means (5) for conveying light between three separate ports (4, 6, 15), such that a state of polarisation of optical pulses of light (3) becomes a particular launch state of polarisation of light (7), and such that one or more particular receive states of polarisation of light (14) become or more separate channels of light (16); optical connector means (8) for making an optical connection between a bi-directional port (6) of the polarisation selecting coupler means (5) and one end (10) of the optical fibre (11); photodetector means (17) for converting the intensity of one or more separate channels of light (16) into one or more separate electrical signals; launch controller means (1);
receiver controller means (18); and processor means (19) for measuring and processing the electrical signals provided by the photodetector means (17) into measurements of the characteristics of the optical fibre (11).
