Abstract:
A remote control device of an acousto-optic tunable filter, comprising:an acousto-optic tunable filter to receive and output a light signal from an optical transmission line, and to control an output state of the light signal received from the optical transmission line based on a surface acoustic wave control signal received through a control port included in said acousto-optic tunable filter; a surface acoustic wave control signal source, which is disposed at a remote place from said acousto-optic tunable filter, to generate the surface acoustic wave control signal,; and a control unit to receive a light signal having information regarding the surface acoustic wave control signal generated by said surface acoustic wave control signal source, to convert the light signal to the surface acoustic wave control signal suitable for controlling said acousto-optic tunable filter, and to supply the converted surface acoustic wave control signal to the control port of said acousto-optic tunable filter.
