A fiber optic cable (FOC) is a signal transmission cable Used for sending and receiving data. Inside the fiber optic cable is a core made of highly pure glass, with a diameter approximately the size of a human hair, coated with plastic. Data transmission relies on The principle of reflecting the data signal, Which is converted into light signals, from the source to the destination. This could be between telephone exchanges and base stations or Between ground station equipment and signal amplification equipment on telecommunication towers, among others. The principle of data transmission via light signal reflection enables this type of cable to transmit data at speeds nearly as fast as light and with minimal signal loss. Therefore, Fiber Optic Cables can be used to transmit data over longer distances compared to other types of signal transmission cables
