Abstract:
1. A fiber optic cable, said cable comprising: at least one fiber; at least one clear buffer tube surrounding said fiber, with said fiber being loosely held within said clear buffer tube; a jacket surrounding said at least one clear buffer tube, wherein said at least one clear buffer tube is constructed from an extruded transparent polymer that remains clear after extrusion, allowing the arrangement of said fiber within said clear buffer tube to be visible along the entire length of said clear buffer tube, and wherein said at least clear buffer tube is transparent to electromagnetic radiations with a wavelength between 390 nm and 750 nm so that the arrangement of said fiber can be visually inspected by the human eye to allow adjustments to the fiber optic cable production process, if there is a fiber length differential between said fiber and said clear buffer tube greater than 0.3% to 1% or −0.3% to −1%.
