Abstract
An intermittent-connection-type optical fiber ribbon in which a plurality of optical fiber core wires are disposed in parallel, and which includes: a connecting part where adjacent optical fiber core wires are connected; and a non-connecting part where adjacent optical fiber core wires are not connected, the connecting parts and the non-connecting parts are provided intermittently in a longitudinal direction, the non-connecting parts are not provided in the longitudinal direction between two the optical fiber core wires, the connecting part is recessed, and in a case where, in the longitudinal direction, a is length of the connecting part, b is length of a part where the non-connecting part between different optical fiber core wires overlap, c is length of the non-connecting part, and p is an interval of the connecting parts, c/a≥1.5, b≤50 mm, and (c/a)×p≥200 mm are set.
