Keywords:Future high capacity and long-reach access networks including WDM-PON, OFDM-PON, TWDM-PON

We propose a long-reach coexisting PON system that adjusts the splitting-ratios of asymmetrical splitters to suit area characteristics. Experiments confirm optical loss-budget enhancement of 6.1 dB in specific areas without active devices.
