摘要：In a method of breaking an optical fiber, wherein the fiber is scored transverselyand tensioned to cause a crack to propagate completely across the fiber, tensionsufficient to cause the crack to propagate is applied after, but not during, the scoringstep. During the scoring step the fiber is subjected to a controlled tension insufficient tosever the scored fiber. The resulting broken fiber ends generally are flat andperpendicular, and thus suitable for making low-loss interconnections. Preferredapparatus for breaking the fiber has a common actuator providing sequential control ofindividual means for locating, scoring and tensioning the fiber. The common actuator maybe rotational, facilitating powered operation by a drive motor, and may be adjustableaxially to enable accurate adjustment of the position at which the fiber is scored. In one,preferred, embodiment suitable for breaking a fiber at a predetermined distance from aconnector already attached to it, the connector skirt screws onto a bush. The projectingend extends through the bush and is gripped by a gripping jaw carried by a memberspaced from the bush and movable away there from to sever the fiber.
