An optical fiber cable includes: a sheath; and a core that is housed in the sheath and includes optical fibers. Recesses and protrusions are disposed alternately in a circumferential direction on an outer circumferential surface of the sheath. The optical fiber cable has a compressive strength of 12.8 N/mm2 or greater and 32.4 N/mm2 or less.

An optical cable is provided. The optical cable includes a tubular, elongate body having an inner surface defining a cavity extending between first and second ends of the elongate body and an optical transmission element located with the cavity. The optical cable includes a coupling or bonding structure non-permanently and non-rigidly joining the outer surface of the optical transmission element to the elongate body at a plurality of periodic contact zones such that relative movement between the optical transmission element and the elongate body is resisted.

An optical communication cable and related systems and methods are provided. The optical cable includes a plurality of wrapped core elements, and the outer surfaces of adjacent wrapped core elements are joined together by discrete bond sections. The discrete bonds sections may be structures such as laser welds, ultrasonic welds, or adhesive material. The discrete bonds hold the wrapped core elements together in the wrapped pattern, such as an SZ stranding pattern.

Provided is an optical fiber ribbon capable of achieving higher density and reduction in diameter and accurately placing optical fibers in V-shape grooves in a fusion machine without failure. The optical fiber ribbon 1 includes three or more of optical fibers 2 arranged in parallel and connecting portions 3 connecting adjacent two optical fibers 2 together, the connecting portions 3 being intermittently provided in each of a ribbon longitudinal direction and a ribbon width direction. The connecting portions 3 are each formed in such a manner as to fill resin into a gap S formed between adjacent two optical fibers 2, and both surfaces of the respective connecting portions 3 are each formed into a recess having a concave shape curved toward a center of the gap S to separate from lines 4,5 each connecting contact points of the optical fibers 2 when being placed on a horizontal surface.

A flexible optical ribbon and associated systems and methods of manufacturing are provided. The ribbon includes a plurality of optical transmission elements and an inner layer comprising a cross-linked polymer material and an outer surface. The outer surface of the inner layer includes first areas having first concentrations of uncrosslinked polymer material and second areas having second concentrations of uncrosslinked polymer material. The first concentrations are greater than the second concentrations. The ribbon includes an outer polymer layer having an inner surface interfacing with the outer surface of the inner layer. The outer polymer layer has a higher level of bonding to the inner layer at the first areas than at the second areas due to the ability of the outer polymer material to bond or crosslink with the larger numbers of uncrosslinked polymer material in the first areas.

Embodiments of the invention include a method for making a partially bonded optical fiber ribbon. The method includes providing a linear array of optical fibers, and applying with an ink jet printing machine a bonding matrix material to at least a portion of at least two adjacent optical fibers. The applied bonding matrix material has a viscosity of approximately 2.0 to approximately 10.0 centipoise (cP) measured at 25 degrees Celsius (° C.). The applied bonding matrix material also has a conductivity of approximately 600 to approximately 1200 millimhos (mmhos). The applied bonding matrix material also has an adhesion of approximately 0.01 to approximately 0.20 Newtons (N). Also, the bonding matrix material is applied to at least a portion of at least two adjacent optical fibers in such a way that the linear array of optical fibers forms a partially bonded optical fiber ribbon.

To improve identifiability of optical fiber ribbons, an exemplary optical fiber ribbon of the invention includes: at least three optical fibers arranged side by side; and a plurality of connection parts that each connect two adjacent ones of the optical fibers, the connection parts being provided intermittently in a length direction of the optical fibers and in a width direction of the optical fibers. A marking for identifying the optical fiber ribbon is provided to each optical fiber. The position, in the circumferential direction, of the marking provided to at least one of the optical fibers is different from the position, in the circumferential direction, of the marking provided to another optical fiber.
