  • Fiber optic device with enhanced resistance to environmental conditions and method
    Patent number: 6865322
    Abstract: A method for producing fiber optic devices having improved intrinsic resistance to external environmental conditions and a fiber optic device made my the method are disclosed. The fabrication method produces an optic device that is treated with deuterium. The method includes a step for treating and/or making optical devices in the presence of a flame produced by the combustion of deuterium gas or a mixture including deuterium.
    Type: Grant

  • Optical fiber coupler packaging arrangement and a method of manufacture the same
    Patent number: 4707069
    Abstract: A protective arrangement for an optical fiber coupler includes a substantially cross-sectionally V-shaped support element which bounds an open channel that receives a portion of the optical fiber coupler. The portion received in the open channel incudes jacketed regions, continuing into bare regions and a coupling region. Respective adhesive bodies secure the jacketed regions of the optical fiber coupler in the open channel of the V-shaped support element. A strip-shaped support element is connected by respective additional bodies of adhesive to the bare regions of the fiber just outside the coupling region. The support elements are of a material having a coefficient of thermal expansion approximating that of the material of the optical fiber coupler. A shrunk tubular shielding element tightly surrounds the V-shaped support element over most of its length and its open ends are closed by respective seals.
