Plenum rated high modulus buffered optical fiber

A plenum rated optical fiber cable, comprising:

• a plenum rated, high modulus optical fiber including:
• a cladded glassy core through which optical signals can be transmitted,
• at least one coating layer surrounding said cladded glassy core which protects said core from microbending forces, and
• a buffer layer material being extruded, said buffer layer material surrounding said at least one coating layer to form a buffer layer that protects said coated optical fiber from mechanical forces and from flame, said buffer layer material comprising a homopolymer of polyvinylidine fluoride.

A plenum rated, high modulus buffered optical fiber, comprising:

• a cladded glassy core through which optical signals can be transmitted;
• at least one coating layer surrounding said cladded glassy core which protects said core from microbending forces;
• and
• a buffer layer material surrounding said at least one coating layer to form a buffer layer that protects said coated optical fiber from mechanical forces and from flame, said buffer layer material comprising a homopolymer of polyvinylidine fluoride and having a flexural modulus of approximately 319,000 psi as per ASTMB 790.
