METHOD AND EQUIPMENT FOR OPTICALLY TRANSMITTING FLOW OF SOLITON OVER VERY LONG DISTANCE |
摘要 |
PURPOSE: To compensate mutual action between solitons so as to increase at least one of a data transmission distance and a bit transmission speed by introducing repulsive mutual action between the respective solitons and the solitons immediately before the solitons and the solitons immediately after. CONSTITUTION: An interval qL between pulses is determined and the case of sending the flow of optical pulses by a mode lock laser Lbm at the bit transmission speed lower than a desired transmission bit transmission speed is indicated. The flow is divided among the N pieces of channels by a divider Sp and phase modulation and change modulation desired so as to stabilize and encode the pulses are applied to the respective channels by the device MPP for simultaneously executing both functions. The device Rt introduces delay time qL/N between the channel and the previous channel and turns the delay time of an (n)-th channel to (n-1)qL/N. A re-coupler Rc generates the flow of the solitons at the desired transmission bit transmission speed. That is, the pulses are separated for qo =qL/N. |
