The signal-to-noise ratio of full duplex fiber-optic telecommunication links using a single fiber with directional couplers is shown to be extremely sensitive to reflections from fiber end terminations and fiber-to-fiber connections. This paper will examine a series of experimental measurements made to determine the reflectance coefficients of several different end terminations and types of connection.
