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.

Abstract: Embodiments of the invention include an electrical cable apparatus. The electrical cable (50) comprises a plurality of paired conductive elements (24) such as twisted pairs of individually insulated copper wire, a flame retardant yarn layer (54) formed or wrapped helically around the conductor pairs or groups of conductor pairs, and a dielectric jacket (32) formed around the conductive pairs and the yarn layer(s). The yarn layer is formed or wrapped around individual conductor pairs or, alternatively, around groups of conductor pairs. The yarn layer is made of, for example, glass yarn, non-woven glass yarn tape, polyimides such as Kapton® tape, polyaramid yarns such as Kevlar® and Nomex®, or other suitable flame retardant materials and/or material combinations. During burn conditions, the flame retardant yarn layer wicks melted insulation from the individual insulated conductor pair elements to reduce the likelihood of melted insulation pooling in the cable and breaching the dielectric jacket of the cable. Also, various yarn layer arrangements maintain separation of the conductor pairs within the cable for reduced crosstalk.
