INTERMITTENTLY BONDED RIBBON WITH INTERMITTENT BONDS CREATED WITH A WET-ON-WET PROCESS

Embodiments of the disclosure relate to an optical fiber ribbon. The optical fiber ribbon includes a plurality of subunits each comprising a subunit coating surrounding at least two optical fibers arranged adjacently to each other. The subunit coating is made of a first material. A plurality of bonds are intermittently formed between adjacent subunits of the plurality of subunits. The plurality of bonds are made of a second material. The optical fiber ribbon includes a diffusion zone at an interface between each of the plurality of bonds and the subunit coating of each adjacent subunit. Each diffusion zone has a gradient of the second material in the first material. Further, the intermittent bonds may include one or more saddle surfaces formed by intersecting convex and concave curvatures. A method of forming such optical fiber ribbons is also disclosed.
