Abstract
A method for forming a fiber optic cable includes paying off a buffer tube such that the buffer tube extends generally along a longitudinal axis. The method further includes binding the buffer tube with a strength member. The strength member has at least one of a tension or a stiffness that is greater than a respective tension or stiffness of the buffer tube. The resulting fiber optic cable includes the strength member extending along a longitudinal axis and the buffer tube wrapping helically about the strength member. A fiber optic cable includes a strength member extending generally along a longitudinal axis. The fiber optic cable further includes a buffer tube wrapping helically about the strength member. The strength member has at least one of a tension or a stiffness that is greater than a respective tension or stiffness of the buffer tube.
