<p>A point/multi-point optical communication system that allows the costs of the subscriber apparatuses to be reduced. In the point/multi-point optical communication system, a single station apparatus is connected to a plurality of subscriber apparatuses by an optical network via a wavelength multiplexer/demultiplexer and an optical fiber transmission path, and each apparatus uses a time division multiplexing or wavelength multiplexing to output an optical signal to the optical network. Further, in this system, the center wavelength of each of the single station apparatus and the plurality of subscriber apparatuses is placed in each of equidistant wavelength slots 21 each having a wavelength slot width ??d, which is divided into two wavelength slots having their respective slot widths ??d1 and ??d2, where ??d1 + ??d2 = ??d and where ??d1 = ??d2, in such a manner that the center wavelength of the station apparatus is placed in the downstream wavelength slot (22) having the wavelength slot width ??d1, while the center wavelength of each of the plurality of subscriber apparatuses is placed in the upstream wavelength slot (23) having the wavelength slot width ??d2.</p> |
