20090129731 | Method for Operating a Device for Splicing Optical Waveguides - A device for splicing optical waveguides comprises a heating unit for heating fiber ends of optical waveguides to be spliced. The optical waveguides are heated by means of the heating unit for a time period, with the heated fiber ends emitting thermal radiation. The thermal radiation is detected in the form of intensity distributions at two different times by a recording unit. Quotients which represent a measure of the splicing temperature which occurs during the splicing process can be determined from the intensity values of the detected intensity distributions. The welding current can be varied as a function of a set value of the quotient, by a comparison with the determined quotient, in order in this way to match the splicing temperature to a desired value. | 05-21-2009 |
20090207402 | Method for Detecting a Core of an Optical Fiber and Method and Apparatus for Connecting Optical Fibers - A method for connecting optical fibers comprises determining the position of the core of a fiber. In response to heating, the optical fibers emit light of which an image can be recorded. The position of the core and/or the eccentricity of the fiber is determined from the recorded image. The core position and/or eccentricity can be used to align fibers for a subsequent fusion splicing operation. The process is suitable for, for example, bend optimized optical fibers. | 08-20-2009 |
20090274423 | Apparatus and Method for Thermal Connection of Optical Waveguides - A splicer comprises a positioning device, in which the fiber ends in general have a residual offset. A memory stores a predetermined relationship between the possible offset and a parameter which controls the application of heat. The parameter which controls the application of heat, for example the splicing time for a predetermined splicing current, is defined on the basis of an actual offset which can be recorded by means of cameras. | 11-05-2009 |
20100086263 | Method of Splicing Microstructured Optical Fibers - After aligning the respective end portions of a first and second optical fiber, the first and second optical fibers are heated by an electric arc during a first time period to melt the respective end portions. The end face of at least one of the first and second optical fibers is positioned away from a center of the electric arc by a distance greater than a quarter of the width of the electric arc. After bringing the respective end portions into contact the respective end portions of the first and second optical fibers are heated during a second time period to form a splice joint. | 04-08-2010 |
20110277510 | APPARATUS AND METHOD FOR THERMAL CONNECTION OF OPTICAL WAVEGUIDES - A splicer comprises a positioning device, in which the fiber ends in general have a residual offset. A memory stores a predetermined relationship between the possible offset and a parameter which controls the application of heat. The parameter which controls the application of heat, for example the splicing time for a predetermined splicing current, is defined on the basis of an actual offset which can be recorded by means of cameras. | 11-17-2011 |
