Abstract
An optical fiber cable includes an elongated optical element portion having an optical fiber, a pair of tensile strength members and an outer jacket. The optical fiber is composed of one or more plastic coated optical fibers, tight-buffered optical fibers or optical ribbon fibers. The pair of tensile strength members is arranged in parallel at both sides of the optical fiber in a width direction of the optical fiber. The outer jacket covers outer circumferences of the optical fiber and the pair of tensile strength members. A frictional coefficient of the outer jacket is equal to or less than 0.20. Shore D hardness of the outer jacket is equal to or more than 60.
