Title: The Innovations of John Sach: A Pioneer in Optical Fiber Technology

Introduction

John Sach, an inventive spirit based in Columbia, SC, is recognized for his significant contributions to the field of optical fiber technology. With four patents to his name, Sach has focused on enhancing the efficiency and reliability of optical fiber systems, paving the way for advancements in communication technologies.

Latest Patents

One of Sach's latest innovations is the splittable optical fiber ribbon, which features a reduced likelihood of fiber fallout along a longitudinal split. His design incorporates border fibers with increased bond strength between their ink-coating and surrounding materials. This improved bond is achieved through a method that involves partially curing the ink covering the border fibers before applying a matrix material and then fully curing both elements simultaneously. The ribbon’s design may also include grooves to facilitate easy splitting into subsets.

Another notable patent is the optical cable with dry core and dry buffer tubes. This innovation includes a buffer tube that contains several water-blocking plugs alongside an optical fiber. The arrangement of these plugs enhances the bond between the optical fibers and the inner tube, achieving a high normalized pullout force above 5.0 N/m. Remarkably, this advancement does not lead to issues typically associated with higher pullout forces, such as signal attenuation.
