    摘要: A method for splicing optical fibers is disclosed. The fibers are held by ferrules with a softening temperature at least 30° C. below that of the lower of the glass transition temperatures of the fibers. The ends of the fibers are actively aligned and brought into contact, then energy is applied to fuse the ferrules together, maintaining the alignment of the ends of the fibers. The ferrules may be a low-melting inorganic glass, such as a lead bismuth borosilicate glass. The method and ferrules of the present invention are especially useful in splicing fibers of dissimilar thermomechanical properties.

    摘要: An apparatus is provided for mechanically attaching an optical fiber to a substrate. The apparatus includes a clamping block formed of malleable material disposed adjacent a substrate. The fiber is disposed adjacent the clamping block and a securing member such as a fastener or spring is used to secure the fiber to the clamping block and substrate. The frictional forces between the fiber and the clamping block eliminate movement of the fiber relative to the substrate.

    摘要: A method of minimizing localized heating of, or minimizing signal losses across a source of loss in, an optical fiber used in transmission of a high power optical signal at an operating wavelength. These methods include the steps of: providing an optical fiber which comprises either (i) a coating characterized by an absorbance of less than about 4.5 dB/cm at the operating wavelength or (ii) a refractive index lower than the refractive index of a cladding layer of the optical fiber by more than about 3×10−3 at the operating wavelength, or (iii) both (i) and (ii); and transmitting a optical signal having a power greater than about 250 mW through the optical fiber, wherein the coating, cladding layer, or combination thereof are selected to minimize localized heating of the optical fiber or to result in a signal loss across a source of loss that is less than about 250 mW at the operating wavelength.
