Abstract: An object of the present disclosure is to provide an optical switch and an optical switch system capable of achieving optical path switching with less power. In order to achieve the above object, an optical switch according to the present disclosure includes a plate-shaped cladding provided with a trench in a thickness direction, opposing lenses exposed to the trench, two optical waveguides coaxially arranged inside the cladding, respective one ends of the optical waveguides being exposed to a surface of the cladding and respective other ends of the optical waveguides opposing each other in the trench via the opposing lenses, a movable transparent body that transmits light of the opposing lenses when the transparent body is sandwiched by the opposing lenses in the trench, and a movable double-sided mirror that reflects light incident from the opposing lenses in a direction opposite to an incident direction when the double-sided mirror is sandwiched between the opposing lenses in the trench.

Abstract: The present disclosure is an optical line switching node device N which includes an optical switch part 2 which performs optical path switching between communication optical fibers F-0, F-1; a communication optical signal extraction part 5-0, 5-1 which extracts some of communication optical signals from one or both of the communication optical fibers F-0, F-1 and photoelectrically converts the extracted some of the communication optical signals; and a communication optical signal storage part 6 which stores some of communication optical signals photoelectrically converted in the communication optical signal extraction part 5-1, 5-1 and uses the stored energy to drive the optical switch part 2.

Abstract: It is aimed to provide an optical node, a remote control system, and a remote control method capable of improving a communication speed of an uplink signal.

Abstract: An object of this disclosure is to enable space saving of an optical fiber connection unit such as an optical switch.
