Wavelength division multiplexing-passive optical network capable of integrating broadcast and communication services |
摘要 |
Disclosed is a wavelength division multiplexing-passive optical network (WDM-PON) that integrates broadcast and communication data, and transmit using WDM. An optical line terminal (OLT), connected to a broadcasting network and an Internet protocol (IP)-network, receives a digital broadcast signal from the broadcasting network and a first communication signal from the IP network, and transmits them as a single (broadcast/communication) integrated optical signal after photoelectric conversion, and further transfers a second communication signal from a service user to the IP network. An OLT/ONU on the user side transfers integrated optical signal from OLT to the user, and transfers channel-information data of a digital broadcast desired by the user and user data including the second communication signal from the user to the OLT. A first WDM demultiplexer WDM-demultiplexes the single signal and transfers it to the OLT/ONU. A first WDM multiplexer WDM-multiplexes the user data and transfers it to the OLT.
