ABSTRACT:
A dual wavelength reflectometer for single mode fibre is provided with separate lasers (5, 6) with emission wavelengths at 1300 and 1550 nm whose outputs are combined using a single mode optical fibre wavelength multiplexer (7) of tapered coupler format. The combined output is fed to a single mode optical fibre beam splitter (9), also of tapered coupler format, which is constructed to act as a 3 dB splitter for both wavelengths. This beam splitter directs light from the lasers into the fibre under test (10) and back-scattered light from the test fibre n to a photodetector (11).
