Abstract

PURPOSE:To provide excellent resistance to heat, oil and chemicals and to decrease the loss in a connector part by coating a compsn. consisting essentially of a fluoroelastomer on the outside of a glass fiber for optical transmission. CONSTITUTION:A fluoroelastomer is used as a protective covering of a glass fiber for optical transmission. The fluoroelastomer is not particularly limited and, for example, a tetrafluoroethylene/propylene copolymer and various other polymers are used. The polymers having a hardened section such as an unsatd. bond, -CF2X or -CFX unit, -CH3 unit or the like in the molecule are preferred in terms of processability. An Si resin compsn. is coated on the clad type multimode glass fiber for optical transmission consisting essentially of quartz glass and having 125mumphi diameter right after spinning and is baked. The material having the compsn. shown in the table is extrusion-coated thereon to 1.0mm. outside diameter of the covering.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glass fiber for optical transmission, which has excellent kJ heat, oil resistance, and gradient properties, and has a protective coating that adheres well to the glass fiber.

Currently, the field of application of glass fibers for optical transmission is gradually expanding, and there is a demand for glass fibers for optical transmission that can be used in harsh environments such as high-temperature atmospheres exceeding 100'C and exposure to oil and chemicals.

The biggest problem in this case is the protective coating, which must have excellent heat resistance, oil resistance, chemical resistance, and strength, and must be compatible with glass fiber. This is because when exposed to high temperatures, if this adhesion is lost, the protective coating separates from the glass fiber and causes thermal expansion, resulting in an increase in loss of d3C transmission and loss of the glass fiber, especially at the connector. This is because it will cause a disconnection.

Based on prior knowledge, the present inventors tried to find a protective coating that would meet this requirement, but as a result, polyolefins such as nylon and polyurethane have insufficient heat resistance, and for this purpose. cannot be used. Also, judging from heat resistance, silicone rubber and fluororesin are considered, but
Silicone rubber has poor oil resistance and chemical resistance, as well as low strength.
