Abstract: Disclosed is a segmented core optical waveguide fiber having low total dispersion slope and negative total dispersion over an extended wavelength window. A wavelength window of particular interest is that in the range of about 1500 nm to 1600 nm. The waveguide fibers in accordance with the invention also have cabled cut off wavelength below about 1480 nm and attenuation at 1550 nm of less than 0.22 dB/km. Mode field diameter is maintained essentially at the nominal value for dispersion shifted waveguide fiber, i.e., 7.7 .mu.m to 8.7 .mu.m. Embodiments having a center segment and a first and a second annular segment are discussed in detail.

Abstract: 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.

Abstract: La invencion se refiere a un perfil de fibra de guia de onda optica de modo sencillo 18, 20, 22, 24 que provee area efectiva relativamente grande mientras limita la perdida de macroflexion; la gran area efectiva resulta de configurar el nucleo de la fibra de guia onda para desplazar potencia de luz propagada lejos del centro de guia de onda; la perdida de macroflexion, medida mediante disposicion de aguja o prueba de mandril de 20 mm, se mantiene baja por medio de una depresion de indice de limitacion de potencia 24 que rodea la region de nucleo central de la guia de onda; ademas, se consigue baja atenuacion y se controla la longitud de onda critica para proveer una ventana de operacion de telecomunicaciones en la escala de longitud de onda de aproximadamente 1250 nm a 1700 nm.

Abstract: Improved optical waveguide fiber 1 comprise of a central core 10 region surrounded by an inner clad region 12. The second annular region 14 is doped with tantalum. The core 10 is doped with germanium. The first annular region 20 of the inner clad is undoped. The optical fiber 1 has a depressed, annular region 20 located between two adjacent regions of relatively high indexes of refraction. The index of refraction of both adjoining regions 10, 20 is greater than the central region 20.

Abstract: Disclosed is a single mode optical waveguide having a segmented core of at least two segments. The relative refractive index, the index profile and the radial dimensions of the core segments are selected to provide an optical waveguide fiber having properties suitable for a high performance telecommunication system operating in the wavelength window of about 1530 nm to 1570 nm. Embodiments of the invention having two, three and four segments are described.
