    摘要： An optical fiber comprises a glass fiber comprising a core and a cladding, a primary resin layer being in contact with the glass fiber and covering the glass fiber, and a secondary resin layer covering the primary resin layer, wherein the secondary resin layer consists of a cured product of a resin composition comprising a base resin containing a urethane (meth)acrylate oligomer, a monomer, and a photopolymerization initiator and hydrophobic inorganic oxide particles, the content of the inorganic oxide particles is 1% by mass or more and 60% by mass or less based on the total amount of the resin composition, and the glass transition temperature of the secondary resin layer is 60° C. or more and 120° C. or less.

    摘要： A contamination control mat 10 comprising a support layer 16 which is coated on a top surface with a polymeric contamination control layer 17, wherein the support layer 16 comprises a glass fiber reinforced polymer that is printed on a top surface, the polymeric contamination control layer 17 is transparent or translucent, and the printed surface is visible through the polymeric contamination control layer. This provides a thin yet rigid and stable mat 10 that can also display printed information that is protected from damage. The mat 10 is primarily used to meet contamination control needs.

    摘要： An active optical fibre, including: a core; an inner cladding substantially surrounding the core, whereby the core and the inner cladding form an area configured to propagate pump radiation; an outer cladding comprised of at least a third material with at least a third refractive index substantially surrounding the inner cladding, the third refractive index being smaller than the second refractive index, whereby the outer cladding confines pump radiation to the core and the inner cladding; and a coating comprised of a thermally conductive material substantially surrounding the outer cladding, wherein the inner cladding is configured to reduce impact of spatial hole-burning on absorption of the pump radiation as the pump radiation propagates through the active optical fibre, and wherein the thermally conductive material of the coating supports a reduced temperature increase between the area and an outer surface of the coating.
