Transceiver Fiber Optical waa unugga beddelka dhexdhexaadka ah ee gudbinta Ethernet kaas oo beddela lammaane-maroojin fog oo fog si ay ugu lammaaniyaan calaamadaha korantada iyo calaamadaha indhaha ee fog-fog.Waxa kale oo loo yaqaan beddele koronto-dhaliyaha meelo badan.Alaabtan waxaa guud ahaan loo isticmaalaa deegaanka shabakada dhabta ah, halkaasoo fiilooyinka Ethernet aan la dabooli karin, iyo fiilooyinka indhaha waa in la isticmaalo si loo kordhiyo fogaanta gudbinta.Caadi ahaan waxa la dhigaa lakabka gelitaanka si loogu dabaqo shabakadaha aagga magaalooyinka waaweyn ee fiber indhaha;isla mar ahaantaana, waxay kaa caawinaysaa in la isku xidho maylka ugu dambeeya ee fiilooyinka indhaha.magaalada.Shabakadaha aagga maxalliga ah iyo kuwa ka baxsan ayaa iyaguna door weyn ka ciyaara.
Si fudud loo dhigo, doorka transceiver-ka fiber optic-ga waa is beddelka isdhaafsiga ee u dhexeeya calaamadaha indhaha iyo calaamadaha korantada.Calaamadaha indhaha waxa laga soo geliyaa dekedda indhaha, iyo calaamadda korantada waxa ay ka soo baxdaa dekedda korantada (interface head RJ45 crystal head interface), iyo lidkeeda.Nidaamku waa qiyaas ahaan: u beddel signalka korantada una beddelo ishaarka indhaha, ku gudbi fiber-ka indhaha, ka dibna u beddel signalka isha isha korontada ee dhinaca kale, ka dibna ku xidh router, furayaasha iyo qalabyada kale.
