Abstract: Disclosed is a technique for effectively transmitting a plurality of contents under the situation securing minimum QoS. According to the technique, among a plurality of contents to be transmitted to a data reception device, two or more contents are set as main contents, and the remaining contents are set as stand-by contents. One of the two or more main contents is set as a broadcasting content to be broadcasted actually, and the remaining main content is set as a switching content. The data transmission device transmits the two main contents to the data reception device via a high-quality line (main content line) and transmits the remaining stand-by contents via a line of a quality lower than the main content line (proxy data transmission line). Contents are switched by interchanging between a broadcasting content and a switching content and interchanging between a switching content and a stand-by content.

Abstract: An optical transmission device is provided with an external optical modulator including three or more Mach-Zehnder interferometers and outputs a single-sideband optical intensity-modulated signal with suppressed optical carrier component, wherein an optical carrier component and an unnecessary one sideband component contained in the outputted optical signal are suppressed. A light branching section (51) branches an optical signal outputted by an external optical modulator (4) into two signals. A photodetector section (52) converts one of the optical signals to an electric signal. An optical carrier component extracting section (54) extracts an optical carrier component signal that is in the vicinity of a frequency f1 from the electric signal. An optical carrier component suppressing section (56) applies a bias voltage for suppressing the optical carrier component to the external optical modulator (4) based on the signal level of the optical carrier component.

Abstract: A SW (70) receives an Ethernet® signal from an outside of areas E and F. The SW (70) selects and outputs the obtained Ethernet® signal to any one of APs (91a to 91e) in accordance with a network structure managed by the SW (70). The AP (91a to 91e) converts the Ethernet® signal to an electrical signal type wireless LAN signal, which is in turn output to a main station (10). The main station (10) frequency-multiplexes the signal output from each of the APs (91a to 91e), and converts the signal to an optical signal, which is in turn output to sub-stations (20a and 20b). The sub-station (20a and 20b) transmits the signal transmitted from the main station (10) to a terminal in the form of a wireless radio wave. Thereby, when a plurality of communication areas are present, the accommodation capacity of an AP can be effectively utilized in each communication area.

Light sources (101 to 10m) respectively convert inputted electrical signals into a plurality of optical signals respectively having different wavelengths, and respectively output the plurality of optical signals.

A multimode optical transmission path (300) optically transmits the wavelength multiplexed signal in multimode. A mode processing section (400) extracts, from the wavelength multiplexed signal transmitted through the multimode optical transmission path (300), a plurality of optical signals each being in a mode having a particular wavelength and a particular propagation constant.
