Abstract
A fiber optic cable includes a tube, a stack of fiber optic ribbons twisting along a lengthwise axis through the tube, and water-blocking tape positioned at least partially around the stack, between the stack and the tube. The water-blocking tape is folded such that an elevated portion of the water-blocking tape is raised. As the stack twists along the lengthwise axis of the tube, corners of the stack interface with the elevated portion to provide intermittent frictional coupling between the stack and the tube.
