  • Patent number: 9322986
    Abstract: A hybrid cladding for optical fibers used in short data networks. The hybrid cladding surrounds a glass waveguide fiber and is surrounded by a primary coating. The hybrid cladding has low adhesion to the primary coating. The low adhesion permits stripping of the primary coating from the hybrid cladding without damaging the hybrid cladding and without leaving residue of the primary coating on the surface of the hybrid cladding. The hybrid cladding may be formed by curing a composition that includes a monomer with a radiation-curable functional group, a slip component, and a photoinitiator. The radiation-curable functional group may be a (meth)acrylate group. The slip component may contain silicon or silicone and may further contain a radiation-curable functional group. Silicone di(meth)acrylate is an illustrative slip component.

  • Publication number: 20150346452
    Abstract: A method of removing a tight buffer coating from an optical fiber involves positioning an end section of the optical fiber next to an end of a tube, with at least a portion of the the end section including a primary coating and the tight buffer coating. The tube has an inner diameter greater than an outer diameter of the primary coating and an outer diameter less than an outer diameter of the tight buffer coating. The method also involves applying energy to heat the tight buffer coating, inserting the end section of the optical fiber into the tube so that the tight buffer coating contacts the end of the tube, and advancing the end section of the optical fiber along the tube. The tube removes the tight buffer coating from the primary coating as the end section of the optical fiber is advanced.

  • Publication number: 20110300367
    Abstract: Disclosed is a composition that includes a photo-curable base composition that contains one or more acrylate-containing compounds; a photoinitiator that activates polymerization of the photo-curable base composition upon exposure to light of a suitable wavelength; and a photo-acid generating compound that liberates an acid group following exposure to the light of the suitable wavelength. Optical fibers that include the cured product of this composition demonstrate enhanced fatigue resistance, extending lifetime in transient, very small bend applications. Optical fiber ribbons that contain these optical fibers are also disclosed.

The phase shifter functions to rotate the optical signal principal states of polarization to a desired orientation. The phase shifter engages a segment of an optical fiber that is coated with a radiation cured coatings. The coating composition is selected so that in response to a preload comprising the application of a stress of about 80 MPa to said coating at about 80° C. and after a stress-relaxation period of at least about 1 hour, at about 80° C.
