  • Patent number: 7899284
    Abstract: The present invention provides a process for producing an optical connector, an apparatus for producing the same, and a process for forming a polymer coating film on an end face of a fibrous dielectric, which can dispose a refractive index adjuster only onto an end face of an optical transmitting medium with excellent reproducibility. Such a process includes bringing an end surface of the optical transmitting medium close to an end face of a liquid refractive index adjuster, while charging at least one of the optical transmitting medium and the liquid refractive index adjuster, thereby adhering the liquid refractive index adjuster to the end face of the optical transmitting medium, and thereafter solidifying the adhered liquid refractive index adjuster to obtain the refractive index adjuster.
