FIELD: physics. ^ SUBSTANCE: system has an electrooptical conversion system. The electrooptical conversion system is configured to receive an input electrical signal without return to zero, process information related to the input electrical signal without return to zero and generate a first and a second electrical signal based on at least information related to input electrical signal without return to zero. The electrooptical conversion system is also configured to delay the second electrical signal relative the first electrical signal by a defined time interval, process information related to the first electrical signal and delay the second electrical signal, and generate an output optical signal with return to zero, based on at least information related to the first electrical signal and the delayed second electrical signal. The output optical signal with return to zero is an optical differential signal with return to zero, and the output optical signal with return to zero, basically does not have any frequency fluctuation. ^ EFFECT: increased reliability of transmitting optical signals. ^ 56 cl, 16 dwg |
