    摘要： A glass filler of the present invention includes: a glass substrate; and a coating film including a surface treatment agent, the coating film covering at least a portion of a surface of the glass substrate. The glass substrate is a glass fiber having a flat cross-sectional shape. For the glass substrate, when a length corresponding to a minor axis of the flat cross-section of the glass fiber is represented by L1, a length corresponding to a major axis of the flat cross-section of the glass fiber is represented by L2, and a length corresponding to a fiber length of the glass fiber is represented by L3, a ratio of an average of L2 to an average of L1, (average of L2)/(average of L1), is 1.5 or more and 8 or less, the average of L1 is 1.0 µm or more and 10 µm or less, and an average of L3 is 80 µm or more and 160 µm or less. The surface treatment agent includes a silane coupling agent. A proportion of the coating film in the glass filler is 0.05 mass% or more and 2.5 mass% or less.

    摘要： An optical fibre comprising: an optical waveguide comprising a glass core surrounded by a glass cladding; a primary coating surrounding the optical waveguide; a secondary coating, surrounding the primary coating, comprising a cured polymer material obtained by curing a curable coating composition comprising: (a) a polyester obtained by esterification of a reactant A selected from carboxylic acids, triglycerides, and mixtures thereof, having a C 16 -C 24 aliphatic chain comprising at least two double bonds spaced by one carbon atom at most, with a reactant B selected from polyols having at least 3 hydroxyl groups, the polyols being thermally stable up to 300°C; (b) an aromatic glycidyl epoxy resin; (c) an aliphatic polyether hardener containing from 8 to 64 hydroxy groups and/or from 2 to 4 epoxy groups; and (d) a secondary amine compound as curing agent. Preferably, the step of curing is a thermal curing, preferably up to 300°C. When cured by heat, the coating material can be applied during the drawing process of the fibre so as to exploit the heat of the just drawn glass fibre as heat source for curing.
