Abstract

The method for creating an optical fiber ribbon of the present disclosure includes a first step of arranging a plurality of optical fibers in parallel to each other for creating the optical fiber ribbon. In addition, the method includes a second step of intermittently bonding the plurality of optical fibers partially at specific intervals using a matrix material. Further, intermittent bonding of the plurality of optical fibers is in pattern of text. Furthermore, intermittent bonding of the plurality of optical fibers allows the optical fiber ribbon to bend along preferential axis. Moreover, intermittent bonding of the plurality of optical fibers is in pattern of text.
