Abstract
One aspect of the present invention relates to an optical fiber coating compositions having, when cured, a Young's modulus of greater than about 950 MPa and a film to film coefficient of friction of less than about 0.44. Another aspect of the present invention relates to an coated optical fiber having a coating having a modulus of greater than about 950 MPa and a fiber to fiber coefficient of friction of less than about 0.74 measured at a speed of about 0.423 cm/sec and with a weight of about 100 grams. The coatings may include additives such as surfactants, surface agents, slip additives, waxes, and micronized polytetrafluoroethylene. The coated optical fibers of the present invention can be freely and smoothly wound on a spool without the formation of fiber loops, crossovers, or other defects.
