ABSTRACT:
With regard to an optical communications system, in a system using a single optical fiber cable between subscribers and an exchange and in which bi-directional transmission is performed using the same 1.3-.mu.m wavelength, the exchange-to-subscriber signal is a high-speed, wideband signal which is bandwidth limited by means of a lowpass filter, and the subscriber-to-exchange signal is a carrier having a frequency higher than the upper limit of the exchange-to-subscriber signal and which is modulated with a low-speed, narrowband signal.
