WELLENLÄNGEN-ERHALTENDER OPTISCHER SIGNALREGENERATOR |
摘要 |
The invention relates to a wavelength-maintaining purely optical signal regenerator to which degraded optical signals with a high data rate are transmitted and regenerated without opto-electronic or wavelength conversion using compact, non-linear semiconductor components with low power consumption. Said regenerator comprises: an optical clock regeneration stage ( 2 ) which generates synchronized stable optical reset clock pulses for the data signal ( 1 ); at least one semiconductor component that is non-linear with reference to the transmission characteristics for the data signal ( 5,9 ); means for transmitting part of the degraded data signal ( 1 ) to the clock regeneration stage ( 2 ) being configured in such a way that a timed optical reset to achieve transparency occurs; a time-slice control unit ( 3 ) which is connected upstream of the semiconductor component ( 5,9 ) and defines a sequence of data bits in the time gap between two respective clock pulses, means for transmitting the other part of the degraded data signal ( 1 ) to the semiconductor component ( 5,9 ) at a power at which the semiconductor component ( 5,9 ) relaxing from the condition of transparency exhibits a nonlinear transmission characteristic for the data signal, and a blocking unit ( 6 ) that is connected downstream of the semiconductor component ( 5,9 ) and that removes the reset clock pulses from the data signal path. |
