The challenge for active and passive components design in CWDM PON system co-exist in GEPON and 10 GEPON architecture

In this paper, we proposed a CWDM PON system as a Next Generation PON system coexists with 1.25/2.5GEPON and 10GEPON system. In CWDM PON system the most challenging part is to provide passive and active components in the network. This study focused on the effect of the active and passive component in the developed CWDM PON system.
