Optic fiber
It gives transmission distance. Types fiberoptic
  • Single mode (single mode): Only one mode light propagates. Allow distances up to 400 km and very high speeds. The usual size of 9/125 microns fiber is.
  • Multimode (multi mode): The light is spread by more than one way. . Used for transmission at close range, no more than 2 Km Typical multimode fibers are according to ISO: OM1 (62., Data transmission is changing direction. In a duplex system, each of the fibers is used for transmission in one direction. Therefore, the duplex installations are faster and more efficient.
