Embodiment Construction

[0072] The present invention encompasses a multimode optical fiber that achieves reduced bend loss suitable for high data rate applications and high bandwidth with reduced cladding effects.

[0073] As shown, figure 2 The refractive index profile of an embodiment of an optical fiber according to the present invention is graphically depicted. The fiber consists of a radius r 1 and the central core relative to the alpha index distribution of the outer cladding (eg, outer optical cladding). In general, the radius r of the central core 1 is about 25 microns. The refractive index difference of the central core relative to the outer cladding can have a difference in the order of 11 × 10 -3 and 18×10 -3 between, generally around 11×10 -3 and 16×10 -3 between (e.g. at 13×10 -3 and 16×10 -3 Between) the maximum value Δn 1 . The alpha parameter of the alpha exponential distribution of the central core is typically between about 1.9 and 2.1.

Abstract

The present invention encompasses optical fibers that include a central core having an alpha index distribution relative to an outer cladding, a first depressed groove, an inner cladding, a second depressed groove, and an outer cladding (eg, an outer optical cladding). The volume of the second depressed groove is generally larger than the volume of the first depressed groove. Optical fibers enable reduced bend losses suitable for high data rate applications and high bandwidth with reduced cladding effects.

Description

technical field [0001] The present invention relates to the field of fiber optic transmission, and more particularly to multimode optical fibers with reduced bend loss and high bandwidth suitable for high data rate applications. Background technique [0002] Optical fibers (ie, glass fibers generally surrounded by one or more coatings) conventionally include a fiber core that transmits and / or amplifies optical signals, and an optical cladding that confines the optical signals within the core. Therefore, the refractive index n of the core c Generally greater than the refractive index n of the optical cladding g (ie, n c >n g ). [0003] For optical fibers, the refractive index profile is usually classified according to the graphical appearance of the function relating the refractive index to the fiber radius. Conventionally, the distance r to the center of the fiber is shown on the x-axis, and the difference between the refractive index (at radius r) and the refractiv...
