Coated glass fibers for optical transmission

摘要

In a glass fiber for optical transmission comprising a primary coat, a thermoplastic resin coat, and a buffer coat between the primary coat and the thermoplastic resin coat, the improvement which comprises said thermoplastic resin being a polyamide having a modulus of elasticity of about 2,000 to 8,000 kg/cm2 at a temperature in the range of 20 to 23 DEG C.
