Abstract
Four-wave mixing of transmitted signals in a lightwave transmission system is reduced by (1) grouping the signals in pairs of adjacent frequencies, (2) increasing the frequency of every other pair by a fixed amount, and (3) decreasing the frequency of the remaining pairs by the same fixed amount, where the fixed amount is less than the permitted variation of the ITU grid.
