A systematic derivation of the Coupled Nonlinear Schrodinger Equations (CNLSE) governing nonlinear pulse propaga- tion in a weakly birefringent monomode optical flber based on a multiple-scale perturbation solution of the semilinear vector wave equa- tion for the electric fleld in a (randomly) birefringent flber medium is presented. The analysis of the nonlinear propagation characteristics of optical pulses based on a numerical solution of the CNLSE is deferred to the second part of this contribution.
