Optical fiber ntau transceiveryog ib qho khoom siv zoo heev thiab hloov tau yooj yim. Kev siv ntau yog los hloov cov teeb liab hluav taws xob hauv cov sib tw twisted rau hauv cov teeb liab optical. Nws feem ntau yog siv rau hauv Ethernet tooj liab cables uas tsis tuaj yeem npog thiab yuav tsum siv cov fibers kho qhov muag kom ntev mus rau qhov sib kis. Nyob rau hauv qhov tseeb network ib puag ncig, nws kuj ua lub luag haujlwm loj hauv kev pab txuas cov mais kawg ntawm cov kab hluav taws xob fiber ntau mus rau thaj chaw hauv nroog thiab sab nraud. Ib qho kev hloov pauv yog ib qho khoom siv hauv lub network siv rau hluav taws xob (optical) teeb liab xa mus, thiab ua lub luag haujlwm tseem ceeb hauv kev sib txuas lus ntawm cov khoom siv hauv lub network (xws li khoos phis tawj, tshuab luam ntawv, khoos phis tawj, thiab lwm yam).
