Method of manufacturing glass parts for connecting optical fibers, and glass parts for connecting optical fibers manufactured using the methods

   
   

There are provided a method of manufacturing a glass part for connecting optical fibers, which allows insertion of optical fibers into the internal hole of the glass part smoothly, and glass parts for connecting optical fibers manufactured using the method. Predetermined parts of a glass tube having an internal hole are heated while pressure is applied into the internal hole, to expand the predetermined parts, thus forming tapered portions. As a result, a continuous curved surface can be achieved at the boundary between each tapered portion of each obtained glass part and the internal hole thereof, and the surface can be made smooth where the tapers are formed.

É fornecido um método de manufaturar uma parte de vidro conectando fibras óticas, que permite a inserção de fibras óticas no furo interno da parte de vidro lisamente, e as peças de vidro para conectar as fibras óticas manufaturadas usando o método. As peças predeterminadas de um tubo de vidro que tem um furo interno são aquecidas quando a pressão for aplicada no furo interno, para expandir as peças predeterminadas, assim dando forma a parcelas afiladas. Em conseqüência, uma superfície curvada contínua pode ser conseguida no limite entre cada parcela afilada de cada parte de vidro obtida e o furo interno disso, e a superfície pode ser feita lisa onde os atarraxamentos são dados forma.
