Abstract
A circuit arrangement is presented for an optical modulator with an optical modulator diode (MD) driven in the blocking direction which, in addition to a shunt resistor (RN) wired in parallel with the modulator diode, contains a damping resistor (RD) wired ahead of the modulator diode, for attenuating unwanted reflections. The damping resistor is preferably wired ahead of the parallel circuit of modulator diode and shunt resistor, and forms part of the terminal resistance of the connecting line carrying the modulation signal (U.sub.m).
