1. Izakhono zonxibelelwano ezigqwesileyo
Ngokwethiyori, ifayibha enye inokudlulisa iziteshi zelizwi ezili-10 leebhiliyoni ngaxeshanye. Okwangoku, uvavanyo lokudlulisa iziteshi zelizwi ezingama-500,000 ngaxeshanye luye lwaphumelela—amawaka okanye amakhulu amawaka amaxesha angaphezulu kuneentambo ze-coaxial zemveli kunye nee-microwave.
2. Ireyi yomgama omde
I-Optical fiber ine-attenuation coefficient ephantsi kakhulu, kwaye xa i-optical transmission ifanelekile, izixhobo zokwamkela i-optical, i-optical amplifier, ukulungiswa kweempazamo ze-forward, kunye ne-RZ coding modulation technology, njl.njl., ingenza umgama we-relay yakho ufikelele kumawaka eekhilomitha, ngelixa iintambo zemveli zinokudlulisela kuphela i-1.5 km, ii-microwaves zingama-50 km, ayinakuthelekiswa konke konke.
3. Ubumfihlo obuhle
4. Ukuguquguquka okuqinileyo
Inezibonelelo zokungoyiki ukuphazamiseka okuvela kwiindawo ezinamandla zangaphandle ze-electromagnetic, ukumelana nokugqwala, njl.
5. Ubungakanani obuncinci kunye nobunzima obulula.
6. Imithombo emininzi yezinto ezikrwada kunye namaxabiso aphantsi
