摘要	A fiber optic switch (400) includes a fiber optic switching module (100) that receives and fixes ends (104) of optical fibers (106). The module (100) includes numerous reflective light beam deflectors (172) which may be selected 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 deflector (172) which indicate its orientation. A portcard (406) included in the switch (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 received coordinates with the orientation signals received from the deflector (172) and 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 deflectors (172) coupling a beam of light (108) between optical fibers (106).
其他摘要	光纤开关（400）包括光纤切换模块（100），其接收并固定光纤（106）的端部（104）。模块（100）包括许多反射光束偏转器（172），其可以选择成对，用于在一对光纤（106）之间耦合光束（108）。模块（100）还从每个偏转器（172）产生指示其方向的定向信号。包括在开关（400）中的端口卡（406）向模块（100）提供驱动信号，用于定向至少一个偏转器（172）。端口卡（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。端口卡（406）将接收的坐标与从偏转器（172）接收的定向信号进行比较，并调整提供给模块（100）的驱动信号，以减小接收的坐标和定向信号之间的任何差异。开关（400）还采用光学对准以精确地定向成对的偏转器（172），其将光束（108）耦合在光纤（106）之间。
主权项	A fiber optic switching module comprising: a first and a second group of optical fiber receptacles which are separated from each other at opposite ends of a free space optical path, and each of which groups is respectively adapted for receiving and fixing ends of optical fibers; lenses juxtaposed with ends of optical fibers fixed respectively at the first and second groups and disposed along the optical path between groups, each of said lenses being respectively disposed with respect to an end of an associated optical fiber of the first or second group so that a beams of light as may be emitted from the end of the optical fiber pass through said immediately adjacent lens to propagate as a quasi-collimated beams through the optical path from said lens toward said second or first group of optical fiber receptacles; a first and a second sets of reflective light beam deflectors that are both disposed along the optical path between the groups of optical fiber receptacles, each of said sets of light beam deflectors being associated with one of the groups of optical fiber receptacles and having a number of light beam deflectors that equals the optical fibers in the group with which it is associated, each of the light beam deflectors in said first or said second set: being associated with one of the optical fibers in the associated group of optical fiber receptacles; being located along the optical path so the quasi-collimated beam of light as may be emitted from the lens associated with the optical fiber impinges upon the light beam deflector to be reflected therefrom through the optical path; and being energizable by drive signals supplied to said fiber optic switching module to be oriented for reflecting the quasi-collimated beam of light as may be emitted from the associated optical fiber to also reflect off a selected one of the light beam deflectors in said second or said first set; whereby a pair of light beam deflectors, one light beam deflector of the pair belonging to the first set and one belonging to the second set, may be selected and oriented by the drive signals supplied thereto to couple a quasi-collimated beam of light propagating through the optical path from the end of one optical fiber as may be fixed in the optical fiber receptacle either of the first or of the second group to reflect sequentially off the pair of energized light beam deflectors into a selected one of the optical fiber receptacles so as to enter an optical fiber as may be fixed at the second or at the first group of optical fiber receptacles.
