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 optical fibers, which carry information over long distances with minimal loss. This technology is commonly used in telecommunications and internet connections, providing faster and more reliable data transfer compared to traditional copper cables. The main advantage of optical cables is their ability to handle large amounts of data at high speeds. They are less susceptible to interference from electromagnetic fields and can transmit signals over longer distances without the need for signal boosters. This makes them ideal for use in data centers and fiber-optic networks.
