Title: Erik A. Bergqvist and Optical-Fiber Technology.

Introduction

Erik A. Bergqvist is an inventor based in Bergsjö, Sweden. His work includes inventions for handling and organizing optical fibers, with a focus on practical fiber-feeding and cross-connection solutions. He is associated with Telefonaktiebolaget LM Ericsson (publ) and holds 3 patents.

Latest Patents

Bergqvist’s listed patents address two aspects of optical-fiber infrastructure.

“Device for Feeding Optical Fibres into a Duct” describes a device that guides optical fiber into a duct using compressed air. A removable bar contains one or more longitudinal blow passages, each shaped for a particular type of fiber. Air delivered near the rear of the passage creates a Venturi effect that helps propel the fiber forward, while openings near the front and rear support the airflow. The design aims to make fiber feeding easier to handle.

“Component for Cross-Connecting Optofibres” concerns a component that cross-connects optical fibers between different fiber ribbons. Its design allows the ribbon structure to remain intact while fibers are cross-connected or reorganized. A plastic casing surrounds the fibers in a mixing or weaving zone, along with the free fiber ends connected at the component’s input and output sides.

Career Highlights

Bergqvist’s listed inventions focus on improving the installation and organization of optical-fiber systems. The fiber-feeding device uses airflow to advance fibers through a duct, while the cross-connecting component supports changes to fiber routing without dividing the ribbon structure. These approaches address practical handling challenges in fiber-optic networks.

Collaborations

Bergqvist is associated with Telefonaktiebolaget LM Ericsson (publ). His listed coworkers include Bertil Olsson and Peter Lo Curzio.

Conclusion

Erik A. Bergqvist’s patent work reflects a focus on practical optical-fiber handling, from feeding fibers into ducts to cross-connecting them while preserving ribbon structure.
