Abstract
PURPOSE:To reduce the loss of a multi coated optical fiber by measuring the shifting of the external-diameter axis of optical fiber cores from right after the end of intrusion after the start of discharge heating to the start of the operation of the surface tension effect of fused quartz by the discharge heating upon the coated optical fibers. CONSTITUTION:The shifting of the external-diameter axis is detected from right after the end of the intrusion of the start of the discharge heating to the start of the operation of the surface tension effect of the fused quartz by the discharge heating upon the coated optical fibers 10 and when the shift is larger than a critical value, the coated optical fibers are disconnected and the operations are retried. A series of operations can be automated by analyzing an optical fiber image picked up by a TV camera. Further, said external- diameter axis shift is measured and the external diameter is also measured after the end of the intrusion. It is decided by the measurement whether or not the intrusion quantity is proper because when the intrusion quantity is not proper, the core may deforms. In this case, the cores are disconnected and the operations are retried. Consequently, a high-loss connection in nonalignment connecting operation using fixed V grooves 20 is eliminated.
