Abstract
Embodiments of an optical fiber cable are provided. The optical fiber cable includes at least one optical fiber, a buffer tube surrounding the at least one optical fiber, and at least one tensile element wound around the buffer tube. The at least one tensile element has a laylength of at least 200 mm. The optical fiber cable also includes an exterior jacket surrounding the tensile element. The exterior jacket is made up of at least one polyolefin, at least one thermoplastic elastomer, and at least one high aspect ratio inorganic filler. Further, the exterior jacket has an averaged coefficient of thermal expansion of no more than 120(10−6) m/mK.
Claims6
A method of manufacturing a drop cable, comprising the steps of:
- moving a buffer tube containing at least one optical fiber along a processing line at a rate of at least 200 meters/minute;
- winding at least one strand of a tensile element around the buffer tube, the tensile element having a laylength of at least 200 millimeters;
- and
- coating the tensile element with an exterior jacket, the exterior jacket comprising a polyolefin component, a thermoplastic elastomer component, and an inorganic filler component.
