How do cables and fiber optic cables differ?

I. How is the difference between communication cable and fiber optic cable? The difference between communication cables and fiber optic cables: inside the cable is a copper core wire; inside the fiber optic cable is glass fiber. Cable: when the phone will be converted into electrical signals after the sound signal through the line transmission to the switch, and then by the switch through the line will be directly transmitted to the other phone to answer the electrical signals, this call process transmission line is the cable. The cable is mainly copper core wire. Core diameter of 0.32mm, 0.4mm and 0.5mm points, the larger the diameter of the communication ability is stronger; there are also the number of core line points, there are: 5 pairs, 10 pairs, 20 pairs, 50 pairs, 100 pairs, 200 pairs and so on. Fiber-optic cable: when the phone will be converted into electrical signals after the sound signal through the line transmission to the switch, and then the switch will be the electrical signal to the photoelectric conversion equipment (electrical signals into optical signals) through the line to another photoelectric conversion equipment (optical signals into electrical signals), and then to the switching equipment, to the other phone on the phone to answer. The line between the two photoelectric conversion equipment is the fiber optic cable. Specifically, it is only the number of cores, the number of cores: 4, 6, 8, 12 pairs and so on. The difference between communication cable and fiber optic cable: cable internal copper core wire; fiber optic cable internal glass fiber.
