OPTICAL AMPLIFIERS AND OPTICAL TRANSMISSION PATH

摘要

The controlled optical amplifiers (V) for wavelength division multiplex signal transmission in each case have a first control device (OE1, OE2, R1) for gain control and a second dominant control device (OE2, R2, R1) with a substantially slower control response for controlling the output level (P OUT) according to a supplied required value (P SOLL). In the case of a transmission path equipped with these amplifiers, both fast level changes and slow loss changes in the transmission path can be compensated.
