Abstract

An optical transmission system for the transmission of optical signals in a wave-division multiplex on a plurality of neighboring optical carrier wavelengths is characterized by the fiber being doped to form a continuously distributed waveguide amplifier over the entire length of the transmission waveguide. To pump the waveguide amplifier, which is continuously distributed along the transmission waveguide, several arrangements are provided. This system can be operated as a unidirectional system or a bidirectional system.
