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: A mechanism for reducing radial offset in a collimnated optical beam associated with an angled end fiber and minimizing an angular offset caused by collimator lens centration errors is presented. An angled end fiber is oriented in a supporting collimator so that the angled surface of the fiber is parallel to the collimator axis, thereby compensating for the radial offset. The angled end fiber is again so oriented after the angular-offset producing collimator lens rotation (used to determine the optical center of the lens) and the collimator lens is moved in a direction parallel to the collimator axis to provide a desired output focal position for the lens.

Abstract: A mechanism for reducing radial offset in a collimated optical beam associated with an angled end fiber (48) and minimizing an angular offset (52) caused by collimator lens (40) centration errors is presented. An angled end fiber is oriented in a supporting collimator so that angled surface of the fiber is parallel to the collimator axis, thereby compensating for the radial offset. The angled end fiber is again so oriented after the angular-offset producing collimator lens rotation (used to determine the optical center of the lens) and the collimator lens is moved in a direction parallel to the collimator axis to provide a desired output focal position for the lens.
Abstract translation: 提出了用于减小与成角度的端部光纤（48）相关联的准直光束中的径向偏移并且使由准直透镜（40）中心误差引起的角度偏移（52）最小化的机构。 成角度的端部光纤定向在支撑准直器中，使得光纤的成角度的表面平行于准直器轴线，从而补偿径向偏移。 角度端部光纤在角偏移产生准直透镜旋转（用于确定透镜的光学中心）之后再次取向，并且准直透镜在平行于准直器轴线的方向上移动以提供期望的输出焦点位置 镜头。
