摘要:
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.

An optical fiber ribbon includes a plurality of optical fibers encapsulated within a matrix material, where the optical fiber coating(s) and the matrix material(s), and optionally any ink layers thereon, are characterized by compatible chemical and/or physical properties, whereby the fiber coating and matrix and any ink layers therebetween can be reliably stripped from the optical fibers to afford a suitable strip cleanliness. Novel ink formulations that can be used in the making of such fiber optic ribbons, methods of making such ribbons, and their use are also described.

A polarization mode dispersion compensator corrects polarization mode dispersion in an optical signal having a fast polarization mode component, a slow polarization mode component and a time differential between the components. The compensator includes a phase shifter and a variable delay section. An input of the phase shifter is coupled to an optical device that provides an optical signal that exhibits polarization mode dispersion. 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, a residual stress exhibited by said coating comprises at least about 60 MPa, and the coating is capable of transmitting a transverse stress to the fiber to controllably change the birefringence of the fiber.
