    • A method for calibrating a preferred disposition for a moveable first mirror of an optical switch core of a photonic crossconnect device relative to a second mirror thereof, the method comprising the steps of determining approximate geometric coordinates of the first mirror relative to the second mirror, effecting a laser light crossconnection between the first and second mirrors to produce data from which to provide first order corrections to refine the geometric coordinates, and effecting a further laser light crossconnection between the first mirror and a third mirror, to produce data from which to provide second order corrections to further refine the geometric coordinates, whereby to calibrate the first mirror such that upon initiation of a laser light crossconnection involving the first mirror, a switching element detects deviation of the first mirror from the preferred disposition thereof and effects corrective changes.
    • 一种用于校准光子交叉连接装置的光学开关芯相对于其第二反射镜的可移动的第一反射镜的优选配置的方法,所述方法包括以下步骤:确定第一反射镜相对于第二反射镜的近似几何坐标, 在第一和第二反射镜之间的激光交叉连接以产生数据,从该数据提供一阶校正以细化几何坐标,以及实现第一反射镜和第三反射镜之间的另外的激光交叉连接,以产生从其提供第二反射镜的数据 订单校正以进一步细化几何坐标,由此校准第一反射镜,使得在开始涉及第一反射镜的激光交叉连接时,开关元件检测第一反射镜与其优选布置的偏差并且实现校正改变。
