Patent ID: 7324721

Claim:
An optical communication line comprising: a first optical connection with accumulated chromatic dispersion at least partially compensated and comprising: a first optical waveguide portion directly connectable to an output of a first processing station of electromagnetic radiation at a pre-established wavelength; and a second optical waveguide portion coupled to the first portion; an amplifying station provided with a first input directly connected to the second portion in order to receive the radiation and with a first output for amplified radiation; a second optical connection with at least partially compensated accumulated dispersion and comprising: a third optical waveguide portion directly connected to the first output; a fourth optical waveguide portion coupled to said third portion and directly connectable to a second input of a second processing station, said first and third portions being associated to respective first order chromatic dispersions having opposite signs, at least said first and third portions being associated to respective first order chromatic dispersions having, at the pre-established wavelength, a corresponding absolute value lower than or equal to 13 ps 2 /Km.
