1. Iziseko zoBugcisa kunye noHlelo lweFiber Optic Cable

Ukuze siqonde ubuchule be-fiber optics, kufuneka siqale sihlolisise ulwakhiwo lwayo oluphambili kunye neentlobo zayo. Intambo yeFiber OpticIqulathe izinto ezine eziphambili: umbindi (iglasi okanye iplastiki ethwala ukukhanya), i-cladding (ibuyisela ukukhanya ngaphakathi kumbindi), i-buffer coating (ikhusela ekonakaleni komzimba), kunye nejakethi yangaphandle (ukhuseleko lokusingqongileyo). Ngokusekelwe kububanzi bombindi kunye nokwanda kokukhanya, iintambo zefayibha zahlulwe ngokwamaqela amabini:

• Ifayibha yeMowudi enye (i-SMF):Ngombindi omxinwa (malunga ne-9 µm), i-SMF ivumela indlela enye yokukhanya ukuba isasazeke. Isebenzisa imithombo yelaser kwaye ifanelekile kwiindlela zonxibelelwano ezikude, ezifana neentambo ezingaphantsi kolwandle kunye ne-backbones ukusuka kwisixeko ukuya kwisixeko.
