In order to meet the customers'emerging demands for more bandwidth and diverse IP multimedia applications including high definition(HD) video streaming service, KT presents innovative FTTP solution using WDM-PON system. FTTP comprises an OLT inside the central office, a fiber optic distribution network including a passive remote node in the outside plant, and ONU installed on the pole or wall of customers premise. The passive remote node is located in a manhole near the subscribers and does not require any electrical power supply. And finally, UTP cable is connected from ONU to subscribers'IP appliances like PC or HGW or IP-STB. KT finished its FTTP trial service in 2004 and commercial deployment has begun since 2005. With this FTTP solution, each subscriber can enjoy high-speed internet service with speeds of up to symmetric 100 Mbit/s and various IP media applications including HD quality IP video streaming service and high quality video phone service.
