METHOD FOR SETTING OPTICAL FIBER TO INDIVIDUAL ALIGNMENT V GROOVE

摘要

PROBLEM TO BE SOLVED: To make it easy to set optical fibers to individual alignment V grooves and shorten the setting time. SOLUTION: For example, when only two center grooves among V grooves for four units are used, the center V grooves 12B and 12C are made lower than other V grooves 12A and 12D. Then the arms 14 of the V grooves 12A and 12D serve as guides to facilitate the setting of optical fibers 28. When welding operation is started after the optical fibers are set, the upper ends of the empty V grooves 12A and 12D are aligned with the upper ends of the optical fibers 28 to leave no gap between the optical fibers 28 and a clamp.
