摘要： An Ethernet-PON integrates broadcast/communication through time division multiplexing, which provides users with high-speed, high-volume communication data and high-quality, real-time digital broadcast/image data. An OLT performs a switching operation on a plurality of digital broadcast/image data received from an external broadcaster according to respective broadcast/image selection information from users, time-division-multiplexes the data into a broadcast/image signal, multiplexes the signal and communication data from an IP network into a frame, and electro-optically converts the frame and transmits to the frame to ONTs through an optical splitter. Each ONT receives and photoelectrically converts the signal from the OLT, and performs frame & time-slot demultiplexing to output the entire received communication signals and broadcast/image information contained in a time-slot assigned to the ONT to a corresponding user. The ONT receives a communication signal and broadcast/image selection information from the user, and outputs them to the OLT through the splitter.

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.

摘要： An Ethernet-PON that accommodates real-time broadcast/image signals and provides security for broadcast/image signals, allows user authentication without a CAS. An OLT in the Ethernet-PON switches digital broadcast/image data signals from a broadcaster according to respective broadcast/image selection information of users, and scrambles the switched broadcast/image data on a user-by-user basis. The scrambled data is multiplexed and converted to a broadcast/image optical signal, which is transmitted, combined with a communication signal from an IP network, to ONTs through an optical splitter. The ONTs select broadcast/image data from the broadcast/image signals according to the respective broadcast/image selection information.
