Media converters feem ntau muab faib ua ob hom, ib tug yog ib tug Ethernet kis tau tus mob media conversion chav tsev uas pauv luv luv twisted-pair hluav taws xob signals thiab ntev-ntev optical signals, feem ntau hu ua photoelectric converters; Tom qab cov teeb liab kho qhov muag tau hloov mus rau hauv cov teeb liab hluav taws xob, nws tau hloov mus rau lwm qhov teeb meem kho qhov muag, tseem hu ua fiber ntau hloov dua siab tshiab. Cov khoom siv feem ntau yog siv nyob rau hauv qhov chaw network tiag tiag uas Ethernet cables tsis tuaj yeem them thiab cov fibers kho qhov muag yuav tsum tau siv los txuas ntxiv qhov kev sib kis, thiab feem ntau yog nyob rau ntawm txheej nkag ntawm broadband cheeb tsam hauv cheeb tsam network; tib lub sijhawm, lawv pab txuas cov mais kawg ntawm cov kab hluav taws xob kho qhov muag mus rau metro Nws kuj ua lub luag haujlwm loj hauv Web thiab dhau mus.
Peb txhua tus paub tias lub network yog tsim los ntawm ntau yam khoom siv kho qhov muag, thiab fiber ntau optic transceivers yog ib feem tseem ceeb ntawm nws. Thaum txuas lub fiber optic transceiver rau lub network, lub fiber optic cable yuav tsum xub muab coj los ntawm sab nraud. Lub optical cable yog spliced nyob rau hauv lub optical cable box, uas yog, lub davhlau ya nyob twg lub thawv. Kev vuam ntawm optical cables kuj yog kev tshawb fawb. Cov kab hluav taws xob kho qhov muag yuav tsum tau muab tshem tawm, cov fibers nyias hauv cov khoom siv kho qhov muag thiab cov pigtails yog welded, thiab tom qab ntawd muab tso rau hauv lub thawv tom qab vuam. Lub pigtail yuav tsum tau rub tawm, txuas nrog ODF (tus ncej, txuas nrog lub coupler), thiab tom qab ntawd txuas nrog lub jumper nrog lub coupler, thiab thaum kawg lub jumper txuas nrog fiber ntau optic transceiver. Cov kab ke tom ntej ntawm kev sib txuas yog router----hloov---LAN---host. Ua li no, fiber ntau optic transceiver txuas nrog lub network.
