摘要： Control of an interconnection process for optical fibers involves evaluating the status of all modules used in the process and moving an optical fiber through the process in accordance with the status of the modules. Such control allows more than one fiber, and more than one fiber type, to be processed simultaneously. The processing may be optimized using fuzzy logic to track when operations performed by a module are near completion. A graphical user interface displaying the movement of the optical fibers through the process may also be provided.

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. 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.

摘要： An apparatus for integrating steps of a process for interconnecting optical fibers. The apparatus contains a planar surface having a plurality of openings. A plurality of optical fiber processing modules are suspended within the plurality of openings, with each of the modules configured to execute a different step of the optical fiber interconnection process. A material transfer mechanism, such as a robot arm, is arranged above the planar surface and is connected to a controller. The apparatus can incorporate an optical fiber precision handling tool, which holds, transports and aligns the fibers to be processed. The robot arm is operative to pick-up and move the optical fiber precision handling tool between the plurality of modules. This allows the optical fibers to be transferred through a series of process steps without having to re-secure or re-orient the fibers between the steps.

摘要： A calibration apparatus and method for a polishing machine includes a ferrule surrounding a polishing pad and a plurality of sensors attached to the ferrule. Each of the sensors is directed at a location where optical fibers extending downwardly from a leveling device contact the polishing pad. The sensors are infrared sensors that detect a heat signature generated by friction at the contact point between the optical fibers and the polishing pad as the polishing pad spins and revolves relative to the leveling device. The heat signature that is generated corresponds to the pressure existing between the optical fibers and the polishing pad.

摘要： 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.

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： 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.
