Abstract: Embodiments of the invention include an optical fiber preform (30) and a multimode optical fiber drawn therefrom that has improved overfill-launch bandwidth performance without disturbing existing laser-launch bandwidth performance. The optical fiber preform includes a core region (34) configured to have a refractive index with a characteristic differential mode delay with a first portion associated with lower order modes that behaves conventionally and a second portion associated with higher order modes that deviates from conventional behavior in a way that improves overfill-launch bandwidth performance at one operating window without adversely impacting the laser-launch bandwidth performance at the same and other operating windows. Preform configurations conventionally optimized for operation at 850 nm are configured in such a way that their characteristic differential mode delay, at 1300 nm, initially increases in a conventional manner and then flattens out to approximately zero at the higher order modes. At 850 nm, the characteristic differential mode delay initially remains flat at approximately zero, in a conventional manner, and then decreases at the higher order modes.

Abstract: Embodiments of the invention include an optical energy transmission system and apparatus having improved mode coupling. According to embodiments of the invention, an optical energy transmission medium such as an optical fiber (10) includes bubbles (26) formed therein for inducing microbending of the optical energy transmission medium, thus promoting advantageous mode coupling, which improves bandwidth potential by reducing dispersion. The bubbles are formed, for example, in one or more buffer region layers (23,24) and/or at the interface between the coating (16) and buffer regions. The method for manufacturing the inventive optical energy transmission medium includes controllably forming one or more buffer region layers around the coated optical fiber or other transmission medium in such a way that that a desired amount of bubbles is created and maintained within one or more of the buffer region layers and/or at the interface between the coating and buffer regions. The bubbles form controlled perturbations that enhance mode coupling to the extent that bandwidth of the optical fiber is improved. The quantity and size of the bubbles formed in the optical energy transmission medium are controlled by, for example, the amount of moisture present in the applied coating.
