How do submarine cables work? Intambo yangaphantsi kwamanzi yenkwili yefiber optical cables ziintsinga zamehlo ngokwenene, ezisebenzisa iimpawu zokusasaza ukukhanya kwimicu ye-optical ukuhambisa idatha. Nangona kunjalo, intambo ye-submarine optical ayiyofiber elula, eneneni yinkqubo entsonkothileyo yothumelo. I-submarine optical cable system ineenxalenye ezimbini: izixhobo ezingaphantsi kwamanzi kunye nezixhobo zaselunxwemeni. Izixhobo zangaphantsi kwamanzi Iquka ikakhulu intambo yokukhanya, isandisi-lizwi/isiphinda-phindi kunye neyunithi yesebe engaphantsi kwamanzi. Isiphindaphindi sisetyenziselwa ntoni? Njengoko sisazi sonke, nangona isantya esiphezulu kunye ne-bandwidth eyaneleyo yefiber optical, umgama wothumelo lwesignali yi...
