ABSTRACT:
When a data transmission request is received in a node apparatus in an optical LAN system, the node apparatus receives a light of a wavelength assigned to a destinated node apparatus. Where the received light is not a modulated light, the received light will be modulated by a transmitting data, and where the received light is a modulated light, the received light is passed through the transmitting node apparatus without a further modulation.
