Abstract
Embodiments of the invention include an optical fiber minicord cable and a communication system employing the minicord cable. The optical fiber minicord cable includes a buffered optical fiber having a first strength layer formed around the buffered optical fiber, a first fire resistant jacket formed around the first strength layer, a second strength layer formed around the first fire resistant jacket, and a second fire resistant jacket formed around the second strength layer. The first and/or second fire resistant jackets are made of a fluoropolymer such as poly(vinylidene fluoride) (PVDF) or poly(vinyl chloride) (PVC), including PVDF Solef® 32008 and low smoke poly(vinyl chloride) (LSPVC) Apex® 910. The first and/or second strength layers are made of, e.g., polyaramid yarns such as Kevlar® and Nomex®. The buffered optical fibers typically have conventional structure, with the buffer region made of a suitable material such as nylon (e.g., Huls 1670 Nylon), polyolefin, poly(vinylidene fluoride) (PVDF), poly(vinyl chloride) (PVC), or polyester. The optical fiber minicord cable is a plenum-rated, high modulus apparatus that also provides sufficient optical transmission properties. Alternatively, embodiments of the invention include a method of making a plenum-rated, high modulus optical fiber minicord cable. The method includes the steps of providing a buffered optical fiber, forming a first strength layer around the buffered optical fiber, forming a first fire resistant jacket around the first strength layer, forming a second strength layer around the first fire resistant jacket, and forming a second fire resistant jacket around the second strength layer.
