We describe the first RSOA-based WDM/TDM hybrid PON system to enter commercial service. The system, consisting of a 16 × 1.25 Gb/s colorless Gigabit WDM-PON and a legacy TDM-PON with optical-electrical-optical converters, provides the triple-play service using fiber-to-the-home and fiber-to-thenode in a new residential area in Korea.
