Paper Details

optical fiber communication is a way of sending information from one place to another by transmittingpulses of light via optical fiber. Electromagnetic carrier waveform from light are modulated to carry information. Fiberis better than electrical cable for high bandwidth, long distance or immunity to electromagnetic interference. Opticalfiber is very widely used for telecom companies to transmit information signals, internet and cable television signals. In aresearch at Bell lab found internet speed more than 100 petabit kilometre per second using optical fiber. On April 22nd1977 the first line telephone traffic using fiber optics at a 6Mbits/S speed in long beach California. In 2nd generation offiber optic communication accomplished world longest commercial fiber optic network covered 3268 Km & linked 52Community. This system were operating at 1.7 Gb/s bit rate with repeater spacing at every 50 Km. In 3rd generation fiberoptic communication system the improvement bring to commercially operate at 2.5Gb per second with repeater spacingat every 100 km. In 4th generation of fiber optics communication with the use of amplifier bit rate reached to 14Tbit persecond over single 160Km link. 5th generation development focus on extending wavelength range for operating WDM inoptical fiber. Maintenance of bending radius for optical fiber signal propagation. The loss of signal strength which effectthe integrity of data transmission is called bending loss
