4. has less of signals sent 5. crosstalk can not be sent through the fiber in the rope adjacent one which ensures the clarity of the transmitted signal, whether a telephone conversation or TV broadcast. It is also not subject to electromagnetic interference, which makes the transmitted signal as confidential, which is of particular importance for military purposes 6. non-flammable, which reduces the risk of fire 7. require less energy in the generator because the loss during the delivery process a little

Because of these advantages, the optical fiber entered in many industries, particularly telecommunications and computer networks. Also used in medical imaging as well as different kinds of Kmjdzisat high quality of the change in temperature and pressure, including its applications in exploration in the ground. There are different types of modern fiber optic recently discovered called Photonic crystal fiber, because it is made of Photonic crystals characterized by the transfer of light in which the lowest loss.. 1. evidence of movement at very high speeds, reaching more than 100 / Mega Byte Yalthanip

 Each fiber can carry many independent channels, each using a different wavelength of light (wavelength-division multiplexing (WDM)). The net data rate (data rate without overhead bytes) per fiber is the per-channel data rate reduced by the FEC overhead, multiplied by the number of channels (usually up to eighty in commercial dense WDM systems as of 2008[update]). The current laboratory fiber optic data rate record, held by Bell Labs in Villarceaux, France, is multiplexing 155 channels, each carrying 100 Gbit/s over a 7000 km fiber. Nippon Telegraph and Telephone Corporation have also managed 69.1 Tbit/s over a single 240 km fiber (multiplexing 432 channels, equating to 171 Gbit/s per channel). Bell Labs also broke a 100 Petabit per second kilometer barrier (15.5 Tbit/s over a single 7000 km fiber).
