Abstract: A fiber optic switch (400) includes a fiber optic switching module (100) tha t receives and fixes ends (104) of optical fibers (106). The module (100) includes numerous reflective light beam deflectors (172) which may be select ed as pairs for coupling a beam of light (108) between a pair of optical fibers (106). The module (100) also produces orientation signals from each deflecto r (172) which indicate its orientation. A portcard (406) included in the switc h (400) supplies drive signals to the module (100) for orienting at least one deflector (172). The portcard (406) also receives the orientation signals produced by that deflector (172) together with coordinates that specify an orientation for the deflector (172). The portcard (406) compares the receive d coordinates with the orientation signals received from the deflector (172) a nd adjusts the drive signals supplied to the module (100) to reduce any difference between the received coordinates and the orientation signals. The switch (400) also employs optical alignment to precisely orient pairs of deflectors (172) coupling a beam of light (108) between optical fibers (106) .

Abstract translation: 光纤开关（400）包括接收并固定光纤（106）的端部（104）的光纤切换模块（100）。 模块（100）包括多个反射光束偏转器（172），所述反射光束偏转器可被选择为用于在一对光纤（106）之间耦合光束（108）的对。 模块（100）还从每个偏转器（172）产生指示其方向的方位信号。 包括在开关（400）中的端口卡（406）将驱动信号提供给模块（100）以定向至少一个偏转器（172）。 门卡（406）还接收由该偏转器（172）产生的定向信号以及指定偏转器（172）的定向的坐标。 portcard（406）将接收的坐标与从偏转器（172）接收的方位信号进行比较，并调整提供给模块（100）的驱动信号以减小接收的坐标和方位信号之间的差异。 开关（400）还采用光学对准以精确地定向耦合光纤（106）之间的光束（108）的成对偏转器（172）。
