摘要：The transmission device (SEN) is coupled to an optical transmission network(NET) with several reception devices (EMP). This transmits analogue electrical signals, in

the form of modulated optical pulses. This is done in the MHz frequency range by initialconversion into pulse width modulated digital signals, which are fed to an electroopticalmodulator (MOD), associated with an optical pulse generator (PULS). The optical pulsegenerator provides optical pulses with a frequency at least 100 times greater than theupper limit frequency of the analogue electrical signals, which are modulated by thedigitised signals and fed to the transmission network.
