TIGHT BUFFERED OPTICAL FIBERS THAT RESIST SHRINKAGE
A cable may include an optical fiber and a tight buffer layer formed around the optical fiber. Additionally, a conductive toner wire may be coupled to the tight buffer layer in order to reduce shrinkage of the tight buffer layer due to low temperatures. A maximum distance between the optical fiber and the toner wire may be 1.0 mm.
