Optical transmitter and optical transmission method

Abstract:

An optical transmitter and an optical transmission method that enable asynchronous operations between transmitters and between the transmitter and a receiver and do not require a synchronization signal line and a synchronization signal generator for connecting between the devices are provided. An optical transmitter includes a generating part generating transmission information including identification information unique to a device and composed of a plurality of bits and generating transmission data with each bit of the generated transmission information in combination of a light-off state and a light-on state, and a transmitting part transmitting a unique beacon signal by controlling the light-on state and the light-off state of a light emitting part in accordance with the generated transmission data.
