    Ka'idar sadarwa ta gani

    Ka'idar sadarwa ita ce kamar haka. A ƙarshen aikawa, bayanan da aka watsa (kamar murya) ya kamata a fara canza su zuwa siginonin lantarki, sannan a canza siginar lantarki zuwa na'urar laser da laser (madogarar haske) ke fitarwa, saboda tsananin haske ya bambanta da amplitude (mita) na siginar lantarki kuma ta hanyar ka'idar jimlar hasken haske, ana watsa siginar siginar a cikin fiber na gani. attenuated da kuma gurbata bayan an watsa ta nesa. Ana haɓaka siginar da aka rage a mai maimaitawar gani don gyara gurɓataccen igiyar ruwa. A ƙarshen karɓar, mai ganowa yana karɓar siginar gani kuma ya canza shi zuwa siginar lantarki, wanda aka lalatar don dawo da bayanan asali.
