'Iphalethi yombala' ezweni le-fiber optic: kungani ibanga lokudlulisela lamamojula optical lihluka kakhulu
Ezweni lokuxhumana kwe-fiber optic, ukukhethwa kobubanzi bokukhanya kufana nokulungiswa kwemvamisa yomsakazo kanye nokukhetha iziteshi. Kuphela ngokukhetha "isiteshi" esifanele lapho isignali ingadluliselwa khona ngokucacile nangokuzinzile. Kungani amanye amamojula okukhanya enebanga lokudlulisela elingamamitha angu-500 kuphela, kanti amanye angadlula amakhulu amakhilomitha? Imfihlakalo ilele 'embala'.Funda kabanzi -
