RIGENERATORE DI SEGNALI OTTICI PER SISTEMI DI TRASMISSIONE CON BIT RATE ELEVATI |
摘要 |
A pulsed optical signal regenerator device comprises three optical stages ( 11,12,13 ) arranged in cascade between an input ( 14 ) to which is applied a signal S<SUB>i </SUB>to be regenerated and an output ( 15 ) at which is available a regenerated signal S<SUB>r</SUB>. The first stage ( 11 ) comprises a first noise suppressor on the zero for noise reduction in the spaces between the input signal pulses. The second stage ( 12 ) comprises an inverting converter for transferring to a clock signal (Ck) the information carried by the signal outgoing from the first stage and introducing a logical inversion of the signal for transformation of the pulses affected by noise in spaces affected by noise. The third stage ( 13 ) comprises a second noise suppressor on the zero for reduction of the noise in the spaces between the signal pulses output from the second stage. The clock signal can be at a tributary bit rate of the entering signal to obtain a demultiplexer function also. |
