A passive optical network (PON) comes to front for cost reduction of FTTH systems. The PON shares the cost of fiber and an optical line termination (OLT) among several customers. The "triple-play services", broadband internet access, video and telephone on the PON, play the role of an engine for explosive growth of the FTTH. The triple-play services on the PON consist of passive devices, optical splitters and wavelength division multiplexing (WDM) modules, and active devices, an OLT and several optical network units (ONU). This paper reviews the technologies for low cost passive and active devices and describes our arrayed WDM filter module for video distribution and bi-directional transceiver device for OLT and ONU on the PON.
