    Abstract: An improved multimode fiber optic cable is provided. The improved multimode fiber optic cable includes, but is not limited to, a refractive index profile which is designed to compensate for a radially dependent wavelength distribution of laser launch modes coupled into the multimode fiber optic cable in order to minimize modal dispersion within the multimode fiber optic cable. The differential mode delay (DMD) is adjusted as a function of the radius effect by modifying the alpha-profile of the refractive index.

    Abstract: An improved multimode fiber optic cable is designed to compensate for the wavelength distribution and emission pattern of laser sources used in high-speed communication systems. The improved multimode fiber optic cable compensates for the wavelength dependent VCSEL polar emission pattern to reduce modal dispersion. Techniques for reducing the modal dispersion within the improved multimode fiber optic cable allow for improved Bit Error Rate (BER) system performance and/or to achieve greater reach in high bandwidth optical channel links are disclosed. Considerable efforts have been undertaken in the design and production of an improved multimode fiber optic cable to minimize modal dispersion, ignoring the effects of wavelength dependent polar emission patterns in lasers. Material dispersion effects have a significant impact on modal dispersion and by modifying a standard parabolic refractive index profile to compensate for material dispersion effects, overall modal dispersion can be reduced.

    Abstract: A new metric applicable to the characterization and design of multimode fiber (MMF) is described. The metric is derived from a Differential Mode Delay (DMD) measurement and when used in combination with industry-standard metrics such as Effective Modal Bandwidth (EMB) and DMD, yields a more accurate prediction of MMF channel link performance as measured by Bit Error Rate (BER) testing. The metric can also be used in the design of MMF for improved bandwidth performance. When implemented as a test algorithm in production, it can be used to select, sort, or verify fiber performance. This process can yield a multimode fiber design with a greater performance margin for a given length, and/or a greater length for a given performance margin.

    Abstract: A fiber optic connector has a double-clad optical stub fiber with a deep index core-to-inner-cladding profile and a raised index outer-cladding profile. The double-clad optical stub fiber abuts against a single-clad field optical fiber to form an interface across which the primary mode traverses without significantly interfering with higher-order modes. The ratio of the radius of the inner cladding to the radius of the core of the stub fiber is less than 6.5: 1. The index profile of the refractive index of the inner cladding is deep relative to the refractive index of the core to confine the primary mode within the core. The raised refractive index of the outer-cladding pulls the higher-order modes deeper into that region, reducing interference with the primary mode. The core diameters of the field and stub fibers are matched to avoid mode-field diameter mismatch.

    Abstract: A method for compensating for both material or chromatic dispersion and modal dispersion effects in a multimode fiber transmission system is provided. The method includes, but is not limited to measuring a fiber-coupled spatial spectral distribution of the multimode fiber laser transmitter connected with a reference multimode fiber optical cable and determining the amount of chromatic dispersion and modal dispersion present in the reference multimode fiber optic cable. The method also includes, but is not limited to, designing an improved multimode fiber optic cable which compensates for at least a portion of the chromatic dispersion and modal dispersion present in the reference multimode fiber optic cable resulting from the transmitter's fiber-coupled spatial spectral distribution.

    Abstract: A graded index multimode fiber and method of producing the graded index multimode fiber utilize technique of reducing an index profile of the core of the multimode fiber below a standard parabolic index profile. This can be done by changing dopant concentrations in the fiber core over the radius of the fiber core. The result is a multimode fiber having differential mode delay characteristics that are intentionally n minimized. The index profile can be reduced below the standard parabolic index profile over the entire radius of the core, or only for radii above a specified radius.
