ABSTRACT:
An optical communication system is described wherein a center (1) and distant terminals (3, 4) are connected to a fiber-optic network (2). Each of the terminals (3, 4) has a light source (5, 7) and a modulator (6, 8) connected thereto for transmitting optical signals to the center (1). Each of the modulators (6, 8) controls the respective light source (5, 7) in such a way that the light source (5, 7) emits light only within successive first time intervals T.sub.1L, T.sub.2L which are separated by second time intervals T.sub.1D, T.sub.2D and that the first time intervals T.sub.1L, T.sub.2L are shorter than the second time intervals T.sub.1D, T.sub.2D.
