    • The optical switch includes input optical fibers, output optical fibers, a lens, a movable mirror, and an actuator operative to move the mirror. Depending on a voltage applied to the actuator, the actuator selectively set the mirror to a first position corresponding to a first combination of optical paths, through which the light beam travels from the first set of the input optical fibers to the second set of the output optical fibers; and to a second position corresponding to a second combination of optical paths, through which the light beam travels from the first set to the second set. The first combination is different from the second combination, and a number of optical fibers of the first set and the second set is more than two.
    • 光开关包括输入光纤,输出光纤,透镜,可移动反射镜和可操作以移动反射镜的致动器。 根据施加到致动器的电压,致动器选择性地将镜子设置为对应于光路的第一组合的第一位置,光束从第一组输入光纤传播到第二组输出 光纤; 以及对应于光路的第二组合的第二位置,光束通过该光路从第一组传播到第二组。 第一组合与第二组合不同,并且第一组和第二组的多个光纤多于两个。
