Classification: CPC H | IPC H

Claim 4:
5. The optical transmitter of claim 1, wherein the precoder is configured to determine each mean value of a core loss value associated with each core as a product between a first value and a second value, the first value corresponding to a mean of a lognormal random variable representing a total misalignment loss associated with said each core, the second value corresponding to a total crosstalk coefficient associated with said each core, the precoder being configured to determine the total crosstalk coefficient associated with a given core from the crosstalk coefficients representing the crosstalk between said given core and the cores of the multi-core fiber different from said given core, the precoder being further configured to determine the variance value of each core loss value associated with each core of the multi-core fiber as a product between a square of the total crosstalk coefficient associated with said each core and a third value corresponding to the variance of said lognormal random variable representing the total misalignment loss associated with said each core.
