OPTICAL FIBER AND OPTICAL FIBER RIBBON - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240302585 titled 'OPTICAL FIBER AND OPTICAL FIBER RIBBON

The abstract describes an optical fiber with a glass fiber core, cladding, and a coating resin layer. The primary resin layer contains a silicone (meth)acrylate and a photopolymerization initiator, while the secondary resin layer contains a urethane (meth)acrylate and a photopolymerization initiator. The coating resin layer has a low tin content of 150 ppm or less.

Glass fiber core with cladding and coating resin layer
Primary resin layer with silicone (meth)acrylate and photopolymerization initiator
Secondary resin layer with urethane (meth)acrylate and photopolymerization initiator
Low tin content of 150 ppm or less in the coating resin layer

Potential Applications: - Telecommunications - Data transmission - Fiber optic networks

Problems Solved: - Enhanced durability of optical fibers - Improved signal transmission quality

Benefits: - Reduced signal loss - Increased data transmission speeds - Longer lifespan of optical fibers

Commercial Applications: Title: Enhanced Optical Fiber Coating for Improved Signal Transmission This technology can be used in telecommunications, internet infrastructure, and data centers to improve signal quality and transmission speeds.

Questions about the technology: 1. How does the low tin content in the coating resin layer benefit the optical fiber? - The low tin content helps reduce signal loss and improve signal transmission quality. 2. What are the key differences between the primary and secondary resin layers in the coating of the optical fiber? - The primary resin layer contains silicone (meth)acrylate, while the secondary resin layer contains urethane (meth)acrylate, each contributing to the overall durability and performance of the optical fiber.

Original Abstract Submitted

an optical fiber comprises a glass fiber including a core and a cladding, and a coating resin layer for coating the glass fiber; the coating resin layer has a primary resin layer in contact with the glass fiber for coating the glass fiber, and a secondary resin layer for coating the primary resin layer; the primary resin layer includes a cured product of a first resin composition containing a silicone (meth)acrylate and a photopolymerization initiator; the secondary resin layer includes a cured product of a second resin composition containing a urethane (meth)acrylate and a photopolymerization initiator; and the amount of tin contained in the coating resin layer is 150 ppm or less in a mass ratio.
