Title:
Fiber optic cable
Document Type and Number:
Japanese Patent JP6010901
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an optical fiber cable which is coated with a sheath having sufficient mechanism strength and hardness, is free from bleed out in the sheath, allows the sheath to be easily stripped therefrom, and allows easy terminal processing.SOLUTION: An optical fiber cable 1 includes a body part 2 in which a coated optical fiber 5 and tension members 6 disposed in parallel with the coated optical fiber are collectively coated with a sheath 7 into a rectangular shape. The sheath is formed of a resin composition containing 100 pts.mass of polyolefin resin (a) and 20 to 150 pts.mass of non-halogen flame retardant (b) but not containing a transitional lubricant substantially. The resin composition has a die swell of 3 or less, and the sheath has a Shore D hardness of 57 or more and a tensile strength of 15 MPa or more, and a strip force for stripping the sheath from the coated optical fiber is 1 N/cm or less.
