摘要： Disclosed are an apparatus and a method for shortening a processing time at each node in an optical network. A transmission optical cross-connect (OXC) determines a transmission rate corresponding to the transmission speed of the signal to be transmitted. An optical receiver and an optical transmitter are stabilized by means of the transmission rate. In addition, a transmission OXC transmits the transmission rate to an OXC aligned between the transmission OXC and the receiving OXC, thereby stabilizing the OXC. Each of the OXCs detects the transmission speed of the optical signal to be received so that a time required for converting the transmission speed is reduced.

摘要： Disclosed is a device for filtering out a null packet in a data stream for example an MPEG-2 TS (Transport Stream) to avoid bandwidth waste when it is transmitted to a backbone network. The device includes a plurality of receiving interfaces, a filter unit, and a controller. The receiving interfaces receive parallel data, such as DVB-ASI (Digital Video Broadcasting-Asynchronous Serial Interface) inputs as channel-by-channel MPEG-2 data. The filter unit counts the respective numbers of data packets and non-data packets of the data input from the receiving interfaces and filters a null packet in the data. A network transmission unit transmits the filtered data to a backbone network. The controller calculates a bit rate based on both of the count numbers received from the filter unit.

摘要： A system for integrating broadcast and communication technologies includes an optical-line terminal (OLT), a optical-network unit (ONU) and a user gateway, wherein a broadcast signal is processed on the basis of time division multiplexing (TDM) such that the quality of a broadcast service can be ensured. The ONU separates the optical signal transmitted from the OLT into the broadcast signal and the communication signal, processes upstream information transmitted from a user, and optically transmits the broadcast signal and the communication signal selected on a user-by-user basis, on the basis of a time slot. The user gateway opto-electrically converts a time slot-based optical signal transmitted from the ONU, separates the time slot-based optical signal into individual signals, distributes the individual signals on a service-by-service basis, and optically transmits the upstream information from the user to the ONU.
