Abstract
When optical signal power of ONU differs from each other the requirements of an OLT receiver becomes strict and the stable operation of a total PON system can't be obtained. To solve this problem each ONU channel's signal power is measured at the OLT side and control signals to equalize them are generated and sent to each ONU. The proposed scheme is tested after implementation A digital APC circuit is proposed and tested so that it can start or stop LD operation without delay. It helps other ONU to transmit signals without interference and to reduce consuming power.
