OPTICAL AMPLIFIERS AND OPTICAL TRANSMISSION PATH

摘要

The invention relates to regulated optical amplifiers (V) for wavelength multiplex signal transmission, which each comprise a first regulator (OE1, OE2, R1) for regulating transmission gain and a second dominant regulator (OE2, R2, R1) whose regulation behaviour is considerably slower and permits regulation of the output level (POUT) in accordance with a setpoint (POUT) being applied. In a transmission line fitted with such amplifiers both rapid changes in level and slow changes in damping in said transmission line can b e corrected.
