Popis:	In this paper we report on the details of the derivation of approximate closed-form results related to the coherence effect in non-linear noise accumulation, in the context of the GN-model of fiber non-linearity. The coherence effect is particularly important in relation to the non-linearity noise produced by a single transmission channel onto itself. We derive new results, not shown before, that provide a more accurate representation of coherent accumulation of NLI than previous closed-form formulas. The availability of such closed-form formulas is important in the context of real-time management and optimization of physical-layer aware optical networks. Comment: This update fixes a typo that affected the previous document starting with Eq.(39)
