    摘要： An optical device for rearranging wavelength channels in an optical network is disclosed. The optical device has a wavelength selective coupler having one input port and a plurality of output ports coupled to a plurality of input ports of an optical grating demultiplexor such as an arrayed waveguide grating. The wavelength channels in each of the input ports are dispersed by the demultiplexor and are directed to a plurality of output ports of the optical grating demultiplexor. As a result, at least one wavelength channel at each of the input ports of the optical grating demultiplexor is coupled into a common output port. The optical device is useful in passive optical networks wherein a same demultiplexor is used for simultaneous multiplexing and demultiplexing of wavelength channels.

    摘要： An optical interferometer for demodulating a differential phase shift keying optical signal includes a planar lightwave circuit and at least one free space delay line optically coupled to the planar lightwave circuit. The planar lightwave circuit has a waveguide splitter, a waveguide coupler, and a phase adjuster. In operation, the splitter splits the optical signal into equal portions, the phase adjuster adjusts the relative phase of the optical signal portions, and the free space delay line provides one-bit delay between the portions of the optical signal. The delayed signals are mixed in the waveguide coupler. The free space delay line can be made variable for adjustment of the bit delay for operation at different bit rates, and/or for optimization of the interferometer performance.

    摘要： An object of the present invention is to provide a waterproof box capable of improving waterproof performance, and workability and space-saving. The washing water hits the lower face of the first waterproof part in the upper cover, and the upper cover is uplifted, at this time the tapered outer face and the inner face in the first waterproof part and are abutted and engaged to each other, causing the inlet of the small passage to close. Even if water infiltrates, the water infiltrates into the dead end to let the momentum thereof reduce. Further, the water infiltrates into the dead end let the momentum thereof reduce. The water its momentum have been reduced falls. Consequently, it is effective for enhancing waterproof performance to include the dead end.

    摘要： There is provided a bolt support structure which can absorb displacement of a bus bar and prevent the bus bar from bending during fastening of bolt, having a bolt including a head portion and a shaft portion and a mount portion to which the head portion is mounted movable in an axial direction of the shaft portion. The mount portion includes a bottom and upper plates between which a large-diameter portion of the head portion is positioned. The shaft portion and a small-diameter portion of the head portion are passed through a notch of the upper plate. A gap between the bottom and upper plates is larger than the thickness of the large-diameter portion. After the head portion is mounted to the mount portion, the nut is attached to the shaft portion so that the bus bar and the terminal clamp are sandwiched between the head portion and the nut.
