The present invention relates to an optical fiber ribbon, comprising a plurality of adjacent optical fiber units extending in a longitudinal direction and arranged in parallel forming an optical fiber assembly having a width, each of the optical fiber units comprising either a single fiber or a group of at most three optical fibers, preferably two optical fibers, encapsulated with a matrix material; and a plurality of successive elongated rectilinear beads of a bonding material being arranged along a length of said assembly; each of said plurality of beads being configured to form an elongated bond between two adjacent optical fiber units of the plurality of optical fiber units; wherein a first bead forming a first bond connects a first pair of adjacent optical fiber units while the successive bond formed by the successive bead, connects a further pair of adjacent optical fiber units, wherein at least one optical fiber unit of the further pair differs from the optical fiber units of the first pair;wherein at each longitudinal position of the optical fiber assembly there is at most one bond. The present invention moreover relates to a method of producing such an optical fiber ribbon.
