These components include the optical fiber, light source, optical connectors, optical receiver, as well as supporting components like splitters, amplifiers, and filters. You will also learn how different aspects of the product can affect budget and design. Here are. Fiber optic technology utilizes pulses of light to send information across vast distances. Instead of electrical signals traveling through copper wires, digital data is encoded onto light waves that travel through thin strands of glass or plastic. When searching for a fiber optic cable, we need to pay attention not only to the connectors, such as SC to ST fiber cable. The first and most essential component of a fiber optic system is the optical fiber itself.
