A method for processing data in an optical network element is provided, wherein a multicarrier signal is linear pre-coded, and wherein the linear pre-coded signal is modulated. An according optical network element is also suggested.

Method for processing data in an optical network element and optical network element

A method for processing data in an optical network element. A multi-carrier signal is linear pre-coded and the linear pre-coded signal is modulated. A corresponding optical network element is also described.

The arrangement includes a transmitter (-) with two optical sources () generating two optical carrier signals (L, L) having different frequencies. The optical carrier signals (L, L) are combined and divided in a first coupler () and fed to carrier signal inputs of two modulators (). The mixed carrier signals (L+jL, jL+L) are separately modulated by two modulation signals (a(t)) and (b(t)) and the modulated signals ((A+jA), (jB+B)) are combined in a first combiner and emitted as transmission signal (X(t)). Only on demodulator is necessary to regain the modulation signals (a(t), b(t)).
