6. Yiziphi izindinganiso zokufakwa kwekhebula le-fiber optic ngaphansi komhlaba?

Amazinga ahlukahlukene, njengalawo ahlinzekwe yi-Fiber Optic Association (FOA) kanye ne-International Electrotechnical Commission (IEC), aveza izindlela ezingcono kakhulu zokufakwa kwekhebula le-fiber optic elingaphansi komhlaba. Lawa mazinga abhekana nezici ezifana nokubamba ikhebula, ukubekwa kwepayipi, nezinqubo zokuhlola.

7. Ngingayithola kanjani ikhebula le-fiber optic engaphansi komhlaba ngezinjongo zokunakekela?

I-radar ye-Ground-penetrating radar (GPR) kanye nezikhombi zekhebula amathuluzi avame ukusetshenziswa ukuze kutholwe intambo ye-fiber optic engaphansi komhlaba. Lawa mathuluzi asiza ukukhomba indawo ngqo kanye nokujula kwekhebuli ukuze kulungiswe noma kulungiswe imisebenzi.

8. Yimaphi amathuba emisebenzi atholakalayo ekufakweni kwentambo ye-fiber optic engaphansi komhlaba?

Kunesidingo esikhulayo sochwepheshe abanamakhono okufakwa, ukugcinwa, nokuphatha intambo ye-fiber optic engaphansi komhlaba. Amathuba emisebenzi angabandakanya izindima ezifana nochwepheshe be-fiber optic, onjiniyela benethiwekhi, noma abaphathi bephrojekthi ezinkampanini zokuxhumana ngocingo, amafemu okwakha, noma abahlinzeki bezinsiza.

Isiphetho

Kulo mhlahlandlela obanzi, sihlole umhlaba wentambo ye-fiber optic engaphansi komhlaba, sembula izinqubo zokuyifaka, izinzuzo, namathuba emisebenzi. Sifundile ukuthi izindlela zokufaka ezifanele ziqinisekisa kanjani ingqalasizinda yokuxhumana enokwethenjelwa, izinzuzo zekhebula le-fiber optic elingcwatshwe, kanye nemihlahlandlela yokungcwaba ikhebula le-fiber optic yokuhlala ekujuleni okufanele.

 

Ukusetshenziswa komsele ongaphansi komhlaba kunikeza ukuvikeleka okwengeziwe kanye nokuvumelana nezimo, kuyilapho ukuthola indawo enembile nokuphatha ngempumelelo kwekhebula le-fiber optic kunika amandla ukugcinwa okusebenzayo nokuxazulula izinkinga. Siphinde sahlola amathuba emisebenzi ahlukahlukene kule mboni, kusukela kochwepheshe bokufaka izicelo kuya kubaphathi bephrojekthi kanye nezingcweti zokuthengisa.

 

Intambo ye-fiber optic engaphansi komhlaba idlala indima ebalulekile ekusunguleni amanethiwekhi okuxhumana aqinile nathembekile ashayela umhlaba wethu wesimanje. Kusukela ekuthuthukisweni kwenethiwekhi yedolobha lonke kuya ekuthuthukisweni kwezindawo zokuhlala kanye nezicelo zezimboni, izifundo eziyisibonelo zibonise ukuqaliswa ngempumelelo kwale ngqalasizinda ethuthukisiwe.

 

Njengoba ubuchwepheshe buqhubeka nokuthuthuka nesidingo sokuxhuma ngesivinini esikhulu sikhula, imboni yamakhebula e-fiber optic engaphansi komhlaba inikeza ikusasa elithembisayo. Ngokuhlala benolwazi mayelana nentuthuko yakamuva, ukwamukela ukuqeqeshwa namathuba emfundo, nokusebenzisa izindlela zemisebenzi ezitholakalayo, abantu ngabanye bangaba neqhaza ekuthuthukisweni kwengqalasizinda yezokuxhumana ebalulekile futhi babe yingxenye yemboni eguquguqukayo nethuthukayo.

 

Ngakho-ke, masibambe amathuba avezwa yintambo ye-fiber optic engaphansi komhlaba, siqinisekise ukuxhumana okungaguquki nokuphumelelayo njengoba sibheke esikhathini esizayo. Ngokubambisana, singaqhubeka nokuphusha imingcele yokuxhumana futhi sivumele ukuxhumana okushintsha izimpilo futhi kubhebhethekise inqubekelaphambili.
