Claim 0:
1. An optical transmitter for transmitting a vector of information symbols over an optical fiber transmission channel, said fiber transmission channel comprising a multi-core fiber, said vector of information symbols being carried by optical signals propagating along the multi-core fiber according to two or more cores, wherein the optical transmitter comprises a precoder configured to determine a precoding matrix depending on one or more fiber parameters associated with said multi-core fiber and to precode said vector of information symbols by multiplying the vector of information symbols by said precoding matrix,
wherein the precoder is configured to determine a core loss value associated with each of said two or more cores depending on said fiber parameters and at least one misalignment loss value, each core loss value being a random variable of a lognormal distribution defined by a mean value and a variance value, said mean value and variance value being dependent on the fiber parameters and the at least one misalignment loss value.
