How It’s Made: Corning Fiber Optic Cable – Corning Optical Fiber Cable Manufacturing Process

When it comes to fiber optic cables, no brand is more widely used than Corning. Corning fiber optic cables are designed for connecting. They have revolutionized the way the world communicates and are some of the purest, most efficient fiber optic cables in the world. The cables are made of ultra-thin strands of glass and are designed to efficiently transmit beams of light-based information. This video explores how fiber optic cable is made. 

Fiber optic cable by Corning is made from strands of glass that are thinner than individual strands of human hair. They are made using a unique manufacturing process, which results in an ultra-pure glass fiber with low attenuation and low signal loss. Each fiber is made of two kinds of glass, each with unique characteristics that add to the design. Optical fibers consist of three layers. The inner layer or core is in the center. It’s the part of the fiber that light passes through. The core is surrounded by the cladding, which is a covering that keeps light from escaping the core, ensuring that signals stay strong throughout the transmission process. An acrylate coating completes the fiber, protecting the glass interior from any physical damage. 

When it comes to manufacturing Corning optical fibers, the most important factor is precision. Corning makes all of the glass materials used in their fibers to ensure the highest degree of strength and purity for improved performance and longevity. Cable manufactured by corning begins with an outside vapor deposition process, known as OVD for short. Raw materials are super-heated and are deposited in vapor form on a target rod called a preform. This process ensures even dispersion and fiber geometry. The rod is then placed in a consolidation furnace and the glass components are transformed from a porous covering to a solid, pure glass product. The size of the preform determines the length of the fiber that can be drawn from it. Once the glass is heated, the fibers can be drawn using an automated system that controls the speed of the draw and thus the size of the fiber. 

Once fibers are drawn, exterior layers are added to increase strength. Finished fibers are wound onto spools and every centimeter of the fiber is tested to ensure it meets specifications. Fiber reels are then packaged and shipped to customers.
