Abstract
A fiber optic jumper cable having a central axis includes a bend-resistant multimode optical fiber generally arranged along the central axis. A tensile-strength layer surrounds the bend-resistant optical fiber. A protective cover surrounds the tensile-strength layer and has an outside diameter DO in the range 1.6 mm≦DO≦4 mm.
Claims8
A fiber optic jumper cable having a central axis, comprising:
- a bend-resistant multimode optical fiber generally arranged along the central axis, wherein the bend resistance of the multimode optical fiber is such that:
- with one turn around a 10 mm diameter mandrel, the bend-resistant multimode optical fiber exhibits an attenuation increase of less than 0.5 dB at a wavelength of 850 nm;
- with one turn around a 15 mm diameter mandrel, the bend-resistant multimode optical fiber exhibits an attenuation increase of less than 0.2 dB at a wavelength of 850 nm;
- and
- with one turn around a 20 mm diameter mandrel, the bend-resistant multimode optical fiber exhibits an attenuation increase of less than 0.1 dB at a wavelength of 850 nm;
- a tensile-strength layer surrounding the bend-resistant optical fiber;
- and
- a protective cover surrounding the tensile-strength layer and having an outside diameter DO in the range 1.6 mm≦DO≦4 mm, wherein the protective cover is a protective outer layer in the form of a cable jacket, wherein the protective cover comprises polyethylene, and wherein the protective cover is formed from at least 80% polyethylene.
