Optical fiber cord or cable containing a polyethylene filament tensile member
First Claim
1. An optical fiber cord or cable comprising at least one optical fiber and at least one tensile member for reinforcing said optical fiber, each tensile member comprising at least one polyethylene filament having a viscosity average molecular weight of not less than 200,000, a tenacity of not less than 20 g/d, a tensile modulus of not less than 600 g/d, a viscosity rate of the dynamic modulus at an elevated temperature (E'"'"'80°
- C.) to that at room temperature (E'"'"'20°
C.) of not less than 60%, and a section area of not less than 0.018 mm2.
