摘要： A method of controlling an optical fiber splicing machine utilizes a power control mode to control the amount of power delivered to fuse the fibers. In the power control mode, the attenuation is measured while the fusing process is occurring. A rate of attenuation loss is predicted from the measured attenuation values by using an estimator. If the rate of attenuation loss indicates that a threshold insertion loss will be crossed before the next attenuation measurement, the splicing machine is stopped prior to the next attenuation measurement. If the desired attenuation is not achieved, an energy control mode is utilized which controls the amount of energy delivered to fuse the fibers. After delivering this energy, the method measures the attenuation. If not within desired values, the energy mode is repeated. At each iteration the splicing control function utilized by the energy control mode may be reprogrammed. A PID control formula may be used to determine the arc current for each iteration. A system for performing the attenuating splice uses, in addition to an optical fiber splicing machine, a laser and power meter to measure insertion loss as well as a controller to implement the splicing methods.

摘要翻译： 控制光纤拼接机的方法利用功率控制模式来控制输送的功率量以熔化纤维。 在功率控制模式下，在发生定影过程时测量衰减。 通过使用估计器从测量的衰减值预测衰减损耗率。 如果衰减损耗的速率表示在下一个衰减测量之前会超过阈值插入损耗，则在下一个衰减测量之前停止拼接机。 如果没有达到期望的衰减，则利用能量控制模式来控制传输的能量来熔化纤维。 传递此能量后，该方法测量衰减。 如果不在期望的值内，则重复能量模式。 在每次迭代中，由能量控制模式使用的拼接控制功能可以被重新编程。 PID控制公式可用于确定每次迭代的电弧电流。 用于执行衰减接头的系统除了光纤拼接机之外还使用激光和功率计来测量插入损耗以及控制器来实现拼接方法。
