    • 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.
    • 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。

    • A method of controlling an optical fiber splicing machine utilizes an optimized power control mode to control the amount of power delivered to fuse the fibers. The attenuation is measured while the fusing process is occurring and a final jump value is calculated. The final jump value is indicative of the transient attenuation difference that occurs as the splice cools. The optimized power control mode shuts down the splicer when the measured insertion loss is less than or equal to the difference between the estimated final jump value and the desired attenuation. The final jump value may also be recalculated as further data are gathered during the splicing process. If the desired attenuation is not achieved, an optimized energy control mode is utilized which determines optimal energy settings and 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 optimized energy mode is repeated. At each iteration the energy settings are re-determined and the splicing control function utilized by the splicer may be reprogrammed. Furthermore, the estimation parameters used to estimate the final jump may be adjusted between each iteration of the optimized power control mode. These adjustments as well as the determination of the energy settings may be aided by a knowledge base and intelligent control techniques that learn as a greater number of splicing operations are performed.
    • 控制光纤拼接机的方法利用优化的功率控制模式来控制输送的功率量以熔化纤维。 在定影过程发生时测量衰减,并计算最终跳跃值。 最终跳转值表示随着接头冷却而发生的瞬态衰减差异。 当测量的插入损耗小于或等于估计的最终跳跃值和所需衰减之间的差值时,优化的功率控制模式关闭接合器。 当拼接过程中收集进一步的数据时,也可以重新计算最终的跳跃值。 如果没有实现所需的衰减,则利用优化的能量控制模式,其确定最佳能量设置并且控制传送以熔化光纤的能量的量。 传递此能量后,该方法测量衰减。 如果不在期望的值内,则重复优化的能量模式。 在每次迭代时,重新确定能量设置,并且可以对拼接器使用的拼接控制功能进行重新编程。 此外,可以在优化的功率控制模式的每次迭代之间调整用于估计最终跳跃的估计参数。 这些调整以及能量设置的确定可以通过知识库和智能控制技术来辅助,知识库和智能控制技术被学习为更多数量的拼接操作。

    • The invention was originally developed to determine the strain-relief capability of a fusion splice protector as well as the compressive stress imparted to a fusion splice by the splice protector. The invention also permits performance and comparative analyses of splice protectors as well as any package in which the optical fiber is at least partially disposed. To those ends a fiber Bragg grating (FBG) is axially arranged relative to the package such that a free or reference section of the FBG protrudes from the package while a shielded section lies within the package. Broadband light is supplied to the FBG which reflects certain wavelengths that are measured by an optical spectrum analyzer. The FBG reflected spectra will be split into two peaks as the reference and shielded sections experience different amounts or types of stress thereby providing a powerful analysis tool. A wavelength shift in the reflected spectra reveals the amount of stress experienced by the reference and free sections and permits a qualitative and quantitative analysis of the stress applied by the package and the package's ability to protect fiber from stress (e.g. such as that imposed by a tension pull test). Measurements may be made after a variety of conditions are changed such as splice protector curing, axial tension application, axial tension release, time, and age accelerating environments. Comparative studies and various other calculations may also be performed to evaluate different packages.

In the power control mode, the attenuation is measured while the fusing process is occurring. The power control mode shuts down the splicer when the measured insertion loss is less than or equal to the target insertion loss value plus a margin value. The margin value accounts for the transient attenuation difference value indicative of the changing attenuation as the splice cools. 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. With these techniques, optical fibers may be spliced having a controlled attenuation to within +/−0.1 dB or better. A system for performing the attenuating splice uses, in addition to a optical fiber splicing machine, a laser and power meter to measure insertion loss as well as a controller to implement the splicing methods.
