摘要： A multimode optical fiber (10) having a first laser bandwidth greater than 220MHz.km in the 850nm window, a second laser bandwidth greater than 500MHz.km in the 850nm window, and a second OFL bandwidth of at least 500MHz.km in the 300nm window is disclosed. The multimode fiber is capable of operating telecommunication systems employing both LED power sources and high power laser sources. Method of making and testing the multimode optical fiber are also disclosed.

摘要： The fiber-coating concentricity of a coated optical fiber is controlled by non-axisymmetrically heating the coating material in the sizing die (40) with respect to the z-axis along which the fiber (47) is drawn. By controlling the temperature profile and thus the viscosity profile of the coating material, the amount of coating material applied to each azimuthal position of the fiber is controlled as it exits the sizing die (40). The apparatus that provides the desired temperature profile can also be employed to control the coating diameter.

摘要： A coating assembly for applying a coating to an optical waveguide fiber includes a guide die having a guide die land region (48), a sleeve for containing pressurized coating material (34), a sizing die (38), and a cooling mechanism (40) operatively associated with the guide die to cool the guide die so that a temperature of the pressurized coating material in an area adjacent the guide die land region is lowered. Maintaining the coating at a relatively cool temperature reduces the likelihood of coating flood.

摘要： Disclosed is a dispersion compensated multimode waveguide fiber link. The dispersion of essentially any wavelength can be compensated by adding a compensating waveguide fiber to the link, the compensating waveguide having a profile shape and a μp wavelength which counters dispersion caused by the original waveguide fiber of the link. Analytical expressions relating the compensator waveguide profile and μp to the original link and compensated profile and μp are provided for the embodiment which includes α profiles.
