Abstract

------22/05/2020------(OCR) Page 1 of 1 Abstract of the Invention This invention solves the problem of connecting OFC Round Type optical fibers, which have a round structure with the optical fiber core separate from the cable sheath and can move slightly. This is suitable for very long cable distances and operating in areas with high environmental impact. The invented OFC Round Type optical fiber replaces the existing OFC Flat Type optical fiber used for connecting to buildings. The fusion splicing process requires stripping the insulation from both ends of the OFC Round Type optical fiber before placing each OFC Round Type optical fiber on the specially invented fusion splicer holder, securing it in two positions simultaneously. This is because securing the cable using conventional methods would be inefficient. During fusion splicing, the optical fiber retracts into the outer insulation (cable jacket) due to the fabricated structure that allows the optical fiber to move. After fusion splicing, it is encased in an outer shrinkable tube (Protect Sleeve Tube) (A), which wraps around an adhesive-coated heat shrink tube (B) used for connecting OFC Round Type optical fibers. It can support OFC Round Type optical fiber connections with an outer diameter that meets and exceeds the specified standards. The adhesive inside the outermost heat shrink tube melts and coats the Protect Sleeve Tube (A) and the outer jacket, supporting and protecting the optical fiber from damage, water, moisture, and chemical vapors. The connection point has the same tensile strength as a cable without a connection. ------------ ------02/04/2019------(OCR) Page 1 of 1 page Summary of the Invention This invention solves the problem of splicing OFC Round Type fiber optic cables.

This invention solves the problem of connecting OFC Round Type optical fibers, which have a round structure with the optical fiber in the center, separate from the cable sheath, allowing for slight movement. This is suitable for very long cable distances and operating in areas with high environmental impact. This OFC Round Type cable is designed to replace the previously used OFC Flat Type cables for building connections. The Fusion Splicer process requires stripping the insulation from both ends of the OFC Round Type cable before placing each OFC Round Type cable on the specially invented cable holder of the Fusion Splicer, which holds it in two positions simultaneously. This is because if the cable is held using the conventional method, during the Fusion Splicer operation, the optical fiber will move back into the outer insulation (Cable Jacket) due to its structure. The design allows the optical fiber to move. After the Fusion Splicer, it is covered with a Protect Sleeve Tube, and finally, an outer heat-shrink tube with adhesive inside. This is used to connect OFC Round Type optical fibers and can accommodate OFC Round Type cables with outer diameters that meet and exceed specified standards. The adhesive inside the outer heat-shrink tube melts and coats the Protect Sleeve Tube, providing insulation and protection for the optical fiber, preventing damage from water, moisture, and chemical vapors. The connection point has the same tensile strength as a cable without a connection.
