Abstract: First and second coils have winding axes in a laminated direction of base material layers and are magnetically coupled to each other. First and second capacitors are positioned in the laminated direction on layers different from layers on which the first and second coils are provided. The first and second coils are connected so that the winding directions of the first and second coils are opposite. The second capacitor is connected in parallel to a series circuit of the first coil and the second coil. The first capacitor is connected between a position where the first coil is connected to the second coil and a reference potential electrode. Mutual inductance caused by coupling between the first and second coils and the first capacitor provides a first attenuation pole and a parallel connection circuit of the series circuit and the second capacitor provides a second attenuation pole.

Abstract: An embodiment optical connector includes a fiber having a core through which light is guided and a magnet attached to one end of the fiber, and the magnet has an opening that exposes at least the end face of the core.

Abstract: In optical transmission schemes of the related art, there is a problem of delay dependency on an overhead or a flow size. In a DC network and a supercomputer network, an OCS scheme and an OPS scheme remain in an examination stage. A network of the electrical packet switching is still a main stream. In a scheme of sharing links using a dedicated wavelength, a considerable number of wavelengths is also necessary to provide full connectivity. The number of wavelengths cannot be realized and an unrealistic number considering the usable number of wavelengths such as current used C bands. In an optical network and an optical transmission system of the present invention, burst mode data transmission in which a label-based switching on an exclusively reserved dedicated wavelength is used is performed. Each node has a uniquely allocated wavelength, and thus traffics coexisting in all the network nodes do not collide.
