US Patent 11036000 Optical fiber cable with high fiber count

The present disclosure provides optical fibers with an impact-resistant coating system. The fibers feature low attenuation. The coating system includes a primary coating and a secondary coating. The primary coating and secondary coating have reduced thickness to provide low-diameter fibers without sacrificing protection. The primary coating has high tear strength and is resistant to damage caused by mechanical force. The secondary coating has high puncture resistance. The outer diameter of the optical fiber is less than or equal to 190 μm.
