PURPOSE:To obtain a splicing part of small loss by setting the extent of forcing-in of optical fibers to <=10mum in the case of fusion-splicing between optical fibers of less eccentricity. CONSTITUTION:Single mode optical fibers are put along V grooves to face each other and are forced in and spliced while heated and fused by discharge heating. In this method, the extent of forcing-in for splicing is set to <=10mum when the extent of eccentricity of optical fiber cores of optical fibers is <=0.5%. Thus, fixing V grooves are used and only clads are aligned to splice optical fibers with a small loss of about 0.01dB average, and therefore, the quality of an optical fiber communication line is improved and the splicing device is simplified. |
