Optik fiber, modern telekom\u00fcnikasyon ve veri iletiminde devrim yaratan dikkate de\u011fer bir teknolojik geli\u015fmedir. I\u015f\u0131k darbeleri yoluyla veri aktar\u0131m\u0131 i\u00e7in bir ortam olarak, geleneksel bak\u0131r kablolara g\u00f6re daha y\u00fcksek bant geni\u015fli\u011fi, daha uzun iletim mesafeleri ve elektromanyetik giri\u015fime kar\u015f\u0131 ba\u011f\u0131\u015f\u0131kl\u0131k gibi \u00f6nemli avantajlar sunar.

Ancak modern fiber optik teknolojisinin temelleri 19. y\u00fczy\u0131lda at\u0131ld\u0131. 1840'larda \u0130rlandal\u0131 fizik\u00e7i John Tyndall, optik fiberlerdeki \u0131\u015f\u0131\u011f\u0131 y\u00f6nlendirmenin temeli olan toplam i\u00e7 yans\u0131ma ilkesini g\u00f6sterdi.<\/p>\n

Fiber optik ileti\u015fimin ilk pratik uygulamas\u0131, 1970'lerde Corning Glass Works ve Bell Labs'taki ara\u015ft\u0131rmac\u0131lar\u0131n, \u0131\u015f\u0131k sinyallerini uzun mesafelerde minimum zay\u0131flamayla iletebilen d\u00fc\u015f\u00fck kay\u0131pl\u0131 optik fiberler geli\u015ftirmesiyle ger\u00e7ekle\u015fti.<\/p>\n
