Title: Norimitsu Takaishi: Innovator in Optical Fiber Technology
Introduction
Norimitsu Takaishi is a prominent inventor based in Tokyo, Japan. He is known for his significant contributions to the field of optical fiber technology. His innovative work has led to advancements that enhance the performance of communication systems.
Latest Patents
Takaishi holds a patent for an "Optical fiber tape of low polarization mode dispersion characteristic and method for measuring dynamic viscoelasticity of the optical fiber tape." This invention features an optical fiber tape designed to exhibit low polarization mode dispersion characteristics. It is particularly applicable to dense wavelength multiplex (DWDM) transmission systems, capable of supporting transmission rates from several Gb/s to several tens of Gb/s. The patent reveals that the polarization mode dispersion of the optical fiber tape is related to the loss tangent (tan δ) determined during dynamic viscoelasticity measurements. Specifically, achieving a loss tangent of 0.080 or more for dispersion shift fiber and 0.042 or more for single mode optical fiber can reduce the polarization mode coefficient of dispersion (PMD) to 0.3 ps/√km, which is preferable for realizing a DWDM transmission system.
