    摘要： The optical switch includes: an input port from which beam is input; a dispersing unit that disperses the beam input; a condensing unit that condenses the beam dispersed; a mirror that reflects the beam condensed; and a plurality of output ports from which the beam reflected is output. The mirror rotates around a first axis so that the beam reflected enters one of the output ports, and also rotates around an axis that is selected, according to that which output port the beam reflected enters, from any one of the first axis and a second axis perpendicular to the first axis so that an intensity of the beam output is attenuated.

    摘要： An optical transmitting apparatus is configured such that K pieces of output ports of optical path switching units whose input port is connected to k-th input transmission path are connected to first to K-th output transmission paths except for the k-th output transmission path and to the k-th input port of a dropping unit, and the optical path switching units and the dropping unit outputs light of wavelength which is part or all of WDM light received from said input port from a specific output port, and can output light having a wavelength different from that of the light output from said specific output port from an output port different from said specific output port. Accordingly, while largely reducing the number of optical fiber patch cords necessary in an optical transmitting apparatus and largely reducing the number of spare ports, the flexible expansion of apparatus function can be realized.
