Introduction
James D Marshall is a notable inventor based in Stittsville, Canada. He has made significant contributions to the field of optical fiber technology, holding a total of 5 patents. His work focuses on enhancing the efficiency and effectiveness of optical fiber splicing.
Latest Patents
One of his latest patents is the "Fusion splicing block with electrodes disposed on planar surface." This invention features a consumable fusion block designed for fusing optical fibers. It includes a non-conducting substrate with at least one flat surface, where a pair of electrodes are positioned on either side of a passline. The space between the electrode tips defines an arc region that can be covered to create a semi-enclosed arc region. Additionally, a method for manufacturing multiple fusion blocks from a single slab of non-conducting material is provided.
Another significant patent is the "Fusion splice element for use in splicing optical fibers." This optical fiber splice element consists of a base member with a fusion element that aligns optical fibers for fusion. A covering member is included to form an enclosure with the base member when closed. This covering member can either be a separate component or a hinged lid. At least one of the covering member or the base member features a locking mechanism to maintain closure. The design allows for accommodating one or more optical fibers when in an open position.
