Title:
TIME SYNCHRONOUS SYSTEM
Document Type and Number:
Japanese Patent JP2006229638
Kind Code:
A
Abstract:

To provide a time synchronous system for performing synchronization of time among two or more devices with high accuracy, in a simple constitution.

The time synchronous system, for performing synchronization of time among two or more devices, includes an optical modulation signal output means for generating an optical modulation signal, and a light-receiving means for receiving the optical modulation signal generated from an optical modulation signal generating means. In the time synchronous system, the signal, received by the light-receiving means is demodulated and the synchronization of time among two or more devices, is performed based on the demodulated signal.
