Demonstration of XGS-PON and GPON Co-Existing in the Same Passive Optical Network

This paper discussed on a demonstration of XGSPON and GPON co-existing in the same FTTH optical network distribution (ODN). A replication of an actual GPON FTTH ODN with two stages splitter (2:4 and 1:8) and GPON co-existed with XGS-PON system is assembled in the laboratory. The operation and performance measurement of both co-existing system is demonstrated by using two OLTs (XGS-PON and GPON), five XGS-PON and two GPON Optical Network Units (ONUs) sharing the same fiber distribution panel (FDP). ODN link loss, operating wavelengths and the throughput measurement of both systems are the performance parameters discussed in this paper. The results showed successful operation of XGS-PON and GPON in a coexisting environment.
