Kwixesha lanamhlanje elikhula ngokukhawuleza lolwazi, ukubaluleka kweshishini lonxibelelwano kuye kwavela ngakumbi. Njengenxalenye ephambili yeziseko zonxibelelwano, ukhetho lweentambo ze-optical lubaluleke kakhulu. Njengohlobo olusebenzayo noluzinzileyo lwentambo ye-optical, intambo ye-OPGW (i-optical ground wire) ithandwa ngabasebenzisi abaninzi. Nangona kunjalo, ukujongana neempawu ezininzi kunye neemodeli zeentambo ze-OPGW kwiimarike, kunye namaxabiso ahlukeneyo, indlela yokukhetha imveliso engabizi kakhulu ibe yingqwalasela yabasebenzisi.
Okokuqala, kufuneka sicacise ukuba ixabiso ayisiyiyo kuphela inqobo yokulinganisa indleko-ngempumelelo yeentambo ze-OPGW. Ngokuqinisekileyo, ixabiso ngenye yezinto ekufuneka siziqwalasele kwinkqubo yokuthenga, kodwa okona kubaluleke kakhulu, ukusebenza kunye nomgangatho wemveliso. Ke ngoko, xa sikhetha i-OPGW, kufuneka sithathele ingqalelo ixabiso lentambo ye-OPGW kwiinkalo ezininzi ngokubanzi.
Ukuqonda iiparameters ezisisiseko zokusebenza kweentambo ze-OPGW linyathelo lokuqala ekukhetheni iimveliso ezingabizi kakhulu. Oku kubandakanya inani le-fiber optical cores, uhlobo lwe-fiber optical, ukulahleka kokudluliselwa, iimpawu zomatshini, njl. Ezi parameters zihambelana ngqo nokusebenza kakuhle kunye nokuzinza kweentambo ze-optical cables. Ngokuthelekisa iiparameters zokusebenza kweemveliso ezahlukeneyo, sinokujonga kwangaphambili uluhlu lwemveliso oluhlangabezana neemfuno zethu.
Okulandelayo, kufuneka sinikele ingqalelo kumgangatho weentambo ze-OPGW. Iimveliso ezikumgangatho ophezulu zihlala zisebenzisa izinto ezikumgangatho ophezulu kunye neenkqubo eziphambili zokuvelisa ukuqinisekisa ukuthembeka kunye nokuqina kweentambo ze-optical cables. Xa kuthengwa, sinokujonga ingxelo yokuhlola umgangatho kunye nesiqinisekiso semveliso ukuqonda umgangatho womgangatho wemveliso. Ukongeza, ukuqonda amandla kunye nodumo lomenzi kukwasisiseko esibalulekileyo sokugweba umgangatho wemveliso.
Ukongeza kwintsebenzo kunye nomgangatho, inkonzo emva kokuthengiswa kwakhona yenye yezinto ekufuneka ziqwalaselwe xa ukhetha iintambo ze-OPGW ezingabizi kakhulu. Inkqubo efanelekileyo yenkonzo emva kokuthengisa inokubonelela abasebenzisi ngenkxaso yezobuchwepheshe ngexesha elifanelekileyo kunye nezisombululo zokuqinisekisa ukuba iingxaki ezifunyenwe ngexesha lokusetyenziswa zingasombululwa ngexesha elifanelekileyo. Ngoko ke, xa ukhetha iimveliso, sinokuqonda umgaqo-nkqubo wenkonzo yokuthengisa emva kokuthengisa kunye nomgangatho wenkonzo ukuqinisekisa ukuba sinokufumana inkxaso efanelekileyo ngexesha lokusetyenziswa.
Ekugqibeleni, masibuyele kwisihloko sexabiso. Emva kokuqwalasela ngokubanzi izinto ezifana nokusebenza, umgangatho kunye nenkonzo yokuthengisa emva kokuthengisa, sinokuthelekisa amaxabiso eemveliso ezahlukeneyo kwaye sikhethe iimveliso ezinexabiso eliphezulu lokusebenza. Kufuneka kuqatshelwe ukuba iimveliso ezinamaxabiso aphantsi kakhulu zinokuba nemingcipheko esemgangathweni okanye iingozi zenkonzo enganelanga emva kokuthengisa, ngoko ke asikwazi ukusebenzisa ixabiso njengesiseko kuphela sokukhetha iimveliso.
Isishwankathelo, ukukhetha iintambo ze-OPGW ezingabizi kakhulu zifuna ukuba senze ingqwalasela ebanzi kwiinkalo ezininzi ezifana nokusebenza, umgangatho, inkonzo emva kokuthengisa kunye nexabiso. Ngokufumana ulwazi olunzulu ngolwazi lwemveliso kunye neemeko zemarike, sinokufumana iimveliso ezingabizi kakhulu ezihambelana neemfuno zethu kunye nokubonelela ngeziqinisekiso eziqinileyo zokusebenza ngokuzinzile kwamanethiwekhi onxibelelwano.
