Analysis of cascaded dispersion compensation system

In this paper, a pulse propagation analysis of cascaded compensation scheme using higher order mode propagation is carried out. The output of the cascaded system consists of compensated and uncompensated components. A generalized expression for the compensated and uncompensated components has been derived. Results show that for a broadband efficient mode converter only previous one or two sections contributes to the pulse broadening of the uncompensated components. For 50 sections (2000 km), the ratio of uncompensated to the compensated power is 24 dB for a mode converter efficiency of 100%.
