Explain how a single fiber optic cable can handle two way communication both half and full duplex?

Optical data transmission is the name of the method of sending data through fiber optic cables. One optic cable can contain hundreds if not thousands of optic fibers. Simplex and half duplex systems use only one fiber to communicate. Simplex transmits only in one specific direction, while half duplex can send in both directions but not at the same time. If likened to a walkie-talkie radio, when the talk button is pressed it is transmitting out but will not be able to receive incoming transmission until the talk button is released. In a full duplex system, two fibers are used to communicate. One fiber is transmitting from point A to point B and the other fiber is transmitting back from point B to point A.
