Abstract
The present invention relates generally to a passive optical network (PON)-based video overlay pluggable type optical network device that is easily connected and detached from an indoor optical network terminal (ONT) at a subscriber side, which transmits and receives an optical signal in which a video RF optical signal and a PON optical signal are overlaid, wherein a PON board for receiving and processing the PON optical signals and a video RF board for receiving and processing the video RF optical signals are easily removed for replacement from a housing including an optical sub-assembly (OSA), which separates the PON optical signal and the video RF optical signal, and the PON board and the video RF board are individually designed and configured in a removable manner so that interference between the signals is minimized and selective combinations and production are possible according to various types of PONs and video services.
