Abstract: Polymeric coated optical elements are described herein, which exhibit good optical properties, e.g., low attenuation. Some such coated optical elements comprise an optical element (e.g., an optical fiber) having an outer surface and a thermoplastic polymeric tight buffer coating on at least a portion of the outer surface of the optical element, wherein the polymer-coated optical element exhibits a first attenuation at room temperature of plus or minus about 50% the attenuation of a comparable optical element with no thermoplastic polymeric tight buffer coating thereon, and a second attenuation at room temperature after thermal cycling to a temperature of at least 170° C. that is about 2 times the first attenuation or less.
