The optical communication system comprises at least one transmitter (Tx1, ... Txn) provided with a light source (10) for emitting white light having a wide wavelength band ( lambda 1, ... lambda n), an optical fiber (2) for transmitting white light emitted from the light source and at least one optical switch (21,22) placed along the optical fiber, and at least one received (Rx1, ... Rxn). The optical switch has an optical filter (115,125) for selectively splitting predetermined different wavelengths and reflecting other wavelengths, and a switching device for cutting off or passing lights of the wavelengths split by the optical filter. An optical filter merges light transmitted by the switching device with lights of other wavelengths reflected by the optical filter and transmits it to the optical fiber. <IMAGE> |
