Abstract: A method of cleaving an optical fiber comprises inserting the optical fiber through a bore of a holding member, securing the optical fiber to the holding member with a bonding agent, operating at least one laser to emit at least one laser beam, and directing the at least one laser beam from the at least one laser to the end face of the holding member. At least a portion of the at least one laser beam reflects off the end face of the holding member and is thereafter incident on an end portion of the optical fiber. The at least one laser beam has a laser fluence of less than 100 J/cm 2 and cleaves the end portion of the optical fiber less than 20μm from the end face of the holding member. In an alternative method of cleaving an optical fiber at least one laser is operated so that it emits at least one laser beam that cleaves the end portion of the optical fiber by: (a) ablating some of the end portion of the optical fiber with the at least one laser beam emitted at a first wavelength; (b) tuning the at least one laser to a different wavelength; and (c) ablating an additional amount of the end portion of the optical fiber with the at least one laser beam emited at the different wavelength. Related systems are also disclosed.

Abstract: A system and method for marking a moving surface of a fiber optic cable is provided. The system includes a supply of the fiber optic cable, a laser generating device configured to generate a laser beam that forms markings by interacting with the material of the moving surface of the fiber optic cable. The system includes a movement device moving the fiber optic cable through the system at a speed of at least 50 m per minute. The system includes a laser directing device located in the path of the laser beam and configured to change the path of the laser beam to direct the laser beam to a plurality of discrete locations on the moving surface to form a series of marks on the moving surface. The moving surface includes a plurality of tracking indicia to allow the position of the moving surface to be determined.

Abstract: A crush resistant, kink resistant optical cable including crush resistant, kink resistant optical fiber buffer tubes and systems and method for making the same are provided. The buffer tubes include a depression pattern formed along the outer surface of the buffer tube. The depression pattern provides areas of decreased thickness in the buffer tube facilitating flexibility and kink resistance. The system and method relates to laser ablation for forming the depression pattern in the buffer tube.

Abstract: An optical communication cable and related systems and methods are provided. The optical cable (10) includes a plurality of wrapped core elements (20,22), and the outer surfaces of adjacent wrapped core elements are joined together by discrete bond sections (34). The discrete bond sections (34) may be structures such as laser welds, ultrasonic welds, or adhesive material. The discrete bonds (34) hold the wrapped core elements together in the wrapped pattern, such as an SZ stranding pattern.
