    Abstract: This invention satisfactorily prevents another person from accessing a terminal that is in use, without reducing a bandwidth allocated to a dedicated peer-to-peer path for the terminal that is in use. A controller controls processing of receiving a request from a first terminal for connection to a second terminal, and processing of transmitting, when the second terminal is in use, a notification that connection cannot be established to the first terminal. For example, the controller recognizes that the second terminal is in use on the basis of connection information stored in a storage unit or on the basis of connection information received from another network device that transmits the request for connection to the second terminal transmitted from the first terminal.

    Abstract: There is provided a light emitting element and an optical waveguide that propagates light from the light emitting element. For example, the optical waveguide is an optical fiber or a silicon optical waveguide. The light propagating through the optical waveguide is light having components of a fundamental mode and a first order mode, and the light propagates through the optical waveguide while having a light intensity distribution in which high intensity portions alternately appear in one direction and another direction opposite to the one direction with respect to the center of a core along the optical waveguide. A light intensity distribution at an output end surface of the optical waveguide is a light intensity distribution corresponding to an intermediate position between a first position where the high intensity portion is in the one direction and a second position where the high intensity portion is in the another direction. In a case of propagating the light having the components of the fundamental mode and the first order mode, it is possible to obtain favorable coupling efficiency regardless of a direction of an optical axis deviation, as in a case of propagating light having only the component of the fundamental mode. A cost is thus reduced by reducing accuracy of positional deviation.

    CPC classification number: H04B10/27

    Abstract: There is provided a transmission system, a transmission method, and a transmission device that make it possible to inhibit deterioration in quality of transmission signals while reducing the number of times of compensation on transmission signals in a case where a plurality of devices is connected in a daisy chain. The transmission system includes a plurality of sub devices and a main device that are connected in a daisy chain. The main device includes a main connector connected to the first sub device of the plurality of sub devices, the main connector being configured to output transmission signals of a plurality of channels. The plurality of sub devices each includes a first sub connector connected to a preceding device, the first sub connector being configured to receive the transmission signals, a compensation unit disposed to correspond to a channel obtained as a result of thinning out, at predetermined intervals, channels other than a channel of an own device signal used by the sub device to which the compensation unit belongs, the compensation unit being configured to perform compensation on the transmission signals, and a second sub connector configured to shift channels of the transmission signals received from the preceding device other than the own device signal by the number of channels of the own device signal and output the transmission signals. The present technology is applicable to, for example, a multi-monitor system.
