Abstract: The present invention allows a reduction in power consumed by communications between devices over a network. A transmission-side device transmits a signal including a wake up signal, path information, and a main data signal in this order to the following relay device (switch/router). The relay device activates a circuit in a standby state on a path on the basis of the wake up signal and the path information. Relay devices on the path are sequentially activated, and the main data signal is finally received by a reception-side device.

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.

Here, the second wavelength is a wavelength that enables the optical waveguide to perform propagation in at least the first order mode in addition to the reference mode. For example, a light path adjuster that adjusts a light path such that input light is guided to a core of the optical waveguide, is further included.

Abstract: It is possible to determine, with a simple configuration, that the connection direction of a cable is the reverse direction. A cable is connected for use between a transmission device and a reception device, and transmits data in one direction. A connection direction determination unit determines whether the connection direction is the reverse direction, on the basis of a result of voltage monitoring at a predetermined position on a power-supply line. When the connection direction is determined to be the reverse direction, the information transmission unit transmits information indicating that the connection direction is the reverse direction, to the transmission device or the reception device.

Abstract: There is provided an optical waveguide that performs propagation only in a reference mode at a first wavelength. Communication is performed using light of a second wavelength that enables the optical waveguide to perform propagation in at least a first order mode in addition to the reference mode. When light entering the optical waveguide deviates with respect to an optical axis or deviates angularly, propagation is performed in at least the first order mode in addition to the reference mode, the first order mode being generated due to the deviation with respect to the optical axis or the angular deviation. This results in a reduction in a loss of coupling of optical power. This makes it possible to relax the accuracy with respect to a deviation with respect to an optical axis or an angular deviation, and thus to reduce costs.

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.

Abstract: The coupling loss of optical power on a reception side due to an axis deviation on a transmission side is satisfactorily mitigated. A connector body including an optical path adjusting unit and a lens is provided. The optical path adjusting unit adjusts an optical path such that the diameter of incident light is reduced while the incident angle is kept. The lens collects light whose optical path has been adjusted, and causes the light to be incident on a light receiver. For example, light incident on the optical path adjusting unit is collimated light. Furthermore, for example, the optical path adjusting unit has a through hole in a central portion. While the incident angle of light to the light receiver satisfies an NA, the focal distance of the lens is decreased. This can mitigate the coupling loss of optical power on a reception side due to an axis deviation on a transmission side.
