The kind of optical transmission.
(1) Optical wireless communication (Straightness)(2) Optical fiber (Refractivity)

2017/12/16

The feature of the optical communication< Advantages>(1) it's difficult to be tapped.
(2 )license free(3) High speed data transmission< Disadvantages >(1) When there is an obstruction, it's impossible to betransmitted.
(2) Optic axis is difficult to put together.
(3) It depends on the weather condition. ( rain, fog,snow and air)
