      Yintoni ebangela iLahleko kuthumelo lwefiber optics?

      Kweli nqaku ndiza kuthetha malunga nokuba yintoni ebangela ilahleko kuthumelo lwefiber optics. Masifunde… Isizathu sokuba kutheni i-optical fiber ithathe indawo yosasazo oluphakathi kunye nomgama omde lweentambo zothungelwano kungenxa yokuba usasazo lwefiber optical linelahleko ephantsi, kwaye ilahleko yalo yahlulwe kakhulu koku kulandelayo:...
