摘要:
It is an object of the present invention to provide an optical fiber cable which can reliably prevent increased transmission loss due to damage of the optical fiber as a result of the egg-laying behavior of cicadas. The cable includes at least an optical fiber 1, tension members 6 and a sheath 3. The sheath 3 has a shore D hardness of 55 or more and a minimum distance L from a surface of the optical fiber 1 to an outer surface of the sheath 3 of greater than 0.3 mm. Further, in the cable, the surface of sheath 3 has a coefficient of friction of 0.45 or less and the sheath 3 has a shore D hardness of 57 or more. In addition, the cable is made by using a specific flame retardant composition (P) as the sheath material.
