Advantages:
1.Large communication capacity and long transmission distance; The potential bandwidth of a single fiber is up to 20THz.
2.Anti-electromagnetic interference, good transmission quality, electrical communication can not solve all kinds of electromagnetic interference problems, only optical fiber communication is not affected by all kinds of electromagnetic interference.
3.Fiber size is small, light weight, easy to lay and transport;
4.The material source is rich, the environmental protection is good, is beneficial to save the nonferrous metal copper.
5.No radiation, difficult to eavesdrop, because optical fiber transmission of light waves can not run out of the fiber.
6.Fiber optic cable has strong adaptability and long life.
Cons:
1.Crisp texture, poor mechanical strength.
2.Cutting and connecting optical fiber requires certain tools, equipment and technology.
3.Decoupling and coupling are not flexible.
4.The bending radius of the fiber optic cable should not be too small (>20cm)
5.There are problems with power supply.
