Classification: CPC H | IPC H

Claim 1:
2. The optical transmitter of claim 1, wherein the precoder is configured to:
determine a normalization factor as a ratio between a number of said two or more cores and a sum of the core loss values associated with said two or more cores;
determine, randomly, a first unitary matrix and a second unitary matrix;
determine a diagonal matrix comprising diagonal components, said diagonal components being equal to mean values of random variables defining core loss values associated with said two or more cores;
determine an auxiliary matrix as a product between a square root of the normalization factor, the first unitary matrix, the diagonal matrix, and the second unitary matrix;
the precoder being configured to determine said precoding matrix as an inverse of said auxiliary matrix.
