How do submarine cables work? underwater submarine optical fiber cable Submarine optical cables are actually optical fibers, ezisebenzisa izici zokusakaza zokukhanya kuma-optical fibers ukudlulisa idatha. Nokho, ikhebula le-submarine optical akuyona i-fiber optical elula, empeleni kuwuhlelo oluyinkimbinkimbi lokudlulisela. Isistimu yekhebula ye-submarine optical inezingxenye ezimbili: imishini engaphansi kwamanzi kanye nemishini yasogwini. Imishini engaphansi kwamanzi Ihlanganisa ikakhulukazi ikhebula le-optical, i-optical amplifier/repeater kanye neyunithi yegatsha elingaphansi kwamanzi. Isiphindaphinda sisetshenziselwa ini? Njengoba sonke sazi, naphezu kwesivinini esikhulu kanye nomkhawulokudonsa owanele we-fiber optical, ibanga lokudlulisa isignali li...
