Abstract:
An optical fiber cable includes a plurality of intermittently connected optical fiber ribbons inside a cable sheath, in which a fibrous filler or an FRP using the fibrous filler is provided on at least one pair of diagonals of the two diagonal directions approximately orthogonal to each other inside the cable sheath. An average linear expansion coefficient of the fibrous filler at −40° C. to +70° C. is smaller than an average linear expansion coefficient of the cable sheath at −40° C. to +70° C.
