Title: Innovations by John T Chapin in Optical Fiber Technology

Introduction

John T Chapin is a notable inventor based in Alpharetta, GA (US), recognized for his contributions to optical fiber technology. He holds a total of 12 patents, showcasing his innovative spirit and dedication to advancing the field. His work primarily focuses on developing optical fiber cables that enhance performance and reliability.

Latest Patents

Among his latest patents are two significant inventions: "Optical fiber cable products having a stress indicating capability" and "A fiber optic cable having stress indicating means and a method for making same." The stress indicating means provides a cost-effective method for determining whether an optical cable has been bent, stressed, or otherwise mishandled, which may cause optical loss when the cable is placed in service. Broadly stated, the fiber optic cable according to the instant invention includes an optical fiber, comprised of a core and a cladding, and a stress indicator concentrically disposed about the fiber that changes color when subjected to stress. This innovation allows technicians to visually identify cables that have been bent or mishandled and subject them to testing before installation.

Another notable invention is the "Color-coded optical fiber cable and a method for manufacturing the same." This invention provides a color-coded optical fiber cable that comprises a glass fiber, a buffer surrounding the fiber, which may be comprised of nylon, an aramid fiber strength member surrounding the fiber buffer, and an outer sheath surrounding the aramid fiber strength member. The optical fiber cables are color-coded by using aramid fiber strength members of different colors, allowing technicians to easily determine which miniature jumper cable of a duplex cable is the transmit jumper cable and which is the receive jumper cable.
