摘要
A node for a loop type optical LAN using wavelength division multiplexing includes a light branching device for partially branching light from a loop of the optical LAN and a tunable filter for filtering a signal having a desired wavelength from the light branched by the branching device. The node may further include a light source for transmitting a signal to a loop of the optical LAN, an optical demultiplexer for selecting from the loop light having the same wavelength as the signal transmitted by the light source and an absorbing device for absorbing the entire amount of the signal transmitted by the light source after the signal once circulates the loop and is selected from the loop by the optical demultiplexer.
