Abstract
The present invention relates to a buffered optical fiber which has a high flame resistance and high modulus. The buffered optical fiber comprises a cladded glassy core through which optical signals can be transmitted, at least one coating layer surrounding the cladded glassy core which protects the core from microbending forces, and a buffer layer material that surrounds the at least one coating layer to form a buffer layer that protects the coated optical fiber from mechanical forces and from flame. In the preferred embodiment, the buffer material comprises homopolymer of polyvinylidine fluoride.
