Title: Optical switch control signal transmitter and optical switch controller
Inventor: ARAI MASAHIRO
IPC: H04B10/27
Filed: 2002-01-09
Abstract: <P>PROBLEM TO BE SOLVED: To obtain an optical switch control signal transmitter which optimizes the switching timing of an optical switch to minimize the transmission time of data for passing through the optical switch.  <P>SOLUTION: A control code generator circuit 1 generates a control code for controlling the connection of input data for an optical switch to a desired output with a delay time required for switching the input data by the optical switch. Electric/optical signal converter circuits 2, 3 convert the control code and delayed data to optical signals different in wavelength and a photo coupler 4 combines them into a signal and transmits it over one optical fiber. At the receive side, the control code is separated from the data and decoded to control the optical switch for switching. Thus the switching timing of the optical switch coincides with the data feed timing to optimize the switching time of the switch, thereby minimizing the data transit time of the optical switch 4.  <P>COPYRIGHT: (C)2003,JPO
