Optical cables are a type of cable that transmit data using light signals instead of electrical signals. They are made of thin strands of glass or plastic, known as fibers, which carry information over long distances with minimal loss. This technology is commonly used in telecommunications, internet connections, and cable television. One of the main advantages of optical cables is their ability to handle large amounts of data at high speeds. They are less susceptible to interference from electromagnetic fields compared to traditional copper cables, making them ideal for modern communication systems.
