摘要： Disclosed is a single mode optical waveguide fiber having a segmented core design. In particular, the core comprises three segments (2, 6, 8), each having characteristic dimensions and refractive index profile. By proper choice of index profile in each segment, a waveguide fiber is made which has a mode field diameter of about 9.5, low, positive total dispersion over the operating window 1530 nm to 1565 nm as well as effective area greater than 60 νm2. The profile is further defined by the inner and outer profile volume and the ratio of outer to inner volume. Thus, inner volume is in the range 2.28 to 3.26 % νm2, the outer profile volume is in the range 3.70 to 13.75 % νm2, and the ratio of outer to inner volume is in the range 1.5 to 4.3.

摘要： Disclosed is a single mode optical waveguide fiber designed for use in high performance telecommunication systems. The novel segmented core profile design improves bending performance to provide enhanced resistance to adverse environments. Total dispersion over an extended wavelength window is maintained low by placing the zero dispersion wavelength above the upper limit of the operating window. In addition, cut off wavelength is increased to just below the operating window. Ease of manufacture is retained as is very low waveguide attenuation.

摘要： The core (19) is surrounded by a layer of cladding material (20) and includes a region (22) of depressed refractive index. The inner radius (ai) of this region (22) is greaterthan zero, and the outer radius (ao) thereof is less than the core radius (a). By appropriately selecting the core index depression (22) characteristics such as radial location, width, depth and shape, a fiber having the desired waveguide dispersion characteristics can be designed. Dispersion minimization over a wide wavelength range can be achieved, without adverse affect on system loss.

摘要： An isotopically-altered, silica based optical fiber is provided having lower losses, broader bandwidth, and broader Raman gain spectrum characteristics than conventional silica-based fiber. A heavier, less naturally abundant isotope of silicon or oxygen is substituted for a lighter, more naturally abundant isotope to shift the infrared absorption to a slightly longer wavelength. In one embodiment, oxygen-18 is substituted for the much more naturally abundant oxygen-16 at least in the core region of the fiber. The resulting isotopically-altered fiber has a minimum loss of 0.044 dB/km less than conventional fiber, and a bandwidth that is 17 percent broader for a loss range between 0.044-0.034 dB/km. The fiber may be easily manufactured with conventional fiber manufacturing equipment by way of a plasma chemical vapor deposition technique. When a 50 percent substitution of oxygen-18 for oxygen-16 is made in the core region of the fiber, the Raman gain spectrum is substantially broadened.
