  Here we study incoherent transport through molecular wire treated as a linear
chain of absorbers, where the phase-breaking processes are modeled by the use
of imaginary point-like potentials. The calculations are performed within a
transfer-matrix method of the scattering theory. An analytic expression for the
transmission of a finite chain in obtained, while the electrical current is
then computed with the help of the Tsu-Esaki formula. In particular, it is
shown that the maximal current dependence on the wire length is exponential.
