Abstract
A fiber optic cable and method of manufacturing the same include at least one optical fiber component and at least one strength member disposed adjacent to said at least one optical fiber component. The at least one strength member includes a yarn and a jacket generally surrounding said at least one optical fiber component and said at least one strength member. The yarn includes a coating system having a percentage by weight, based on the dry weight of said yarn, of about 2.0% or less. Other embodiments can include a delta attenuation of about 0.3 dB or less over the range of about 0% to about 1.0% of optical fiber strain, a peak cable core pull-out force of about 1 newton or less, or a space disposed between a cable core and the jacket.
