Isishwankathelo seSikhokelo seCable yeFiber Optic yokuBulala ngokuNgqongqo

2025-03-11

Ndibhala isishwankathelo sesikhokelo esiphezulu seentambo ze-fiber optic zokungcwaba ngqo. Masiqale ngokuqonda ukuba zeziphi kanye kanye iintambo ze-fiber optic zokungcwaba ngqo. Kwinto endiyikhumbulayo, ziintambo ezenzelwe ukugqunywa ngqo phantsi komhlaba ngaphandle kokufuna i-conduit. Oko kwenza ukufakwa kube lula kwaye kubize kancinci, akunjalo?

Intambo yeFiber Optic yokungcwaba ngqo.jpg

Okokuqala, kufuneka ndiwahlule amacandelo abalulekileyo. Ulwakhiwo lwentambo kufuneka lwahluke kwiintambo ze-fiber optic eziqhelekileyo. Mhlawumbi zineeleya zokukhusela. Makhe ndicinge: kukho i-optical fiber ngokwayo, mhlawumbi i-buffer coating, amalungu okuqina afana ne-aramid yarn, kwaye ke uhlobo oluthile lwejakethi yangaphandle eqinileyo. Owu, kwaye mhlawumbi izinto ezithintela amanzi kuba zingaphantsi komhlaba kwaye zinokuvezwa kumswakama.

Iintlobo zeentambo zokungcwaba ngqo – Ndicinga ukuba kukho iindidi ezahlukeneyo ngokusekelwe kwinani leentambo, mhlawumbi imo enye vs imo ezininzi. Kwakhona, ezinye zinokuba nezikhuselo zokukhusela ngakumbi. Iintambo ezixhotyisiweyo zingasebenzisa isinyithi okanye enye into ukuthintela umonakalo ovela kwiimpuku okanye amatye.

Inkqubo yokufaka – kufuneka zingcwatywe nzulu kangakanani? Ndicinga ukuba zimalunga ne-24 ukuya kwi-48 intshi, kuxhomekeke kwindawo kunye neekhowudi zasekuhlaleni. Ukusebenzisa umatshini wokutsala imisele, ukubeka intambo, uze ugcwalise kwakhona. Mhlawumbi bafuna iteyiphu yesilumkiso ngaphezulu kwentambo ukuze balumkise nabani na omba apho kamva. Ukuvavanya emva kokufakela nako kubalulekile, njengokusebenzisa i-OTDR ukujonga ilahleko okanye ukwaphuka.

Iingenelo kunezinye iindlela: ukungabikho kwesidingo see-conduit kusindisa ixesha nemali. Zenzelwe ukumelana neemeko ezinzima phantsi komhlaba. Kodwa kukho neengxaki, njengomonakalo onokubakho ngenxa yokumba okanye oomatshini abanzima ukuba abaphawulwanga kakuhle. Kwakhona, mhlawumbi kubiza kakhulu xa kuthelekiswa neentambo eziqhelekileyo, kodwa kubiza kancinci ekuhambeni kwexesha ngenxa yokungabikho kweendleko ze-conduit.

Izicelo ziya kubandakanya unxibelelwano, i-intanethi, iindawo zasemaphandleni, umkhosi, ii-smart grids, kunye neenkqubo zeCCTV. Iingcebiso zolondolozo: uhlolo oluqhelekileyo, ukujonga ukulahleka kwesignali, kunye nokuba namaxwebhu achanekileyo endawo apho iintambo zibekwe khona.

Imigangatho kunye nokuthobela imithetho – kufuneka kubekho imigangatho yeshishini efana ne-NEC e-US, okanye imigangatho yamazwe ngamazwe ye-ITU-T. Imithetho yasekuhlaleni malunga nobunzulu bomngcwabo kunye neempawu zokhuseleko.

Iingxaki eziqhelekileyo: ukungena kwamanzi ukuba intambo ayivalwanga kakuhle, umonakalo wempuku ukuba ayixhonywanga, kunye noxinzelelo lomzimba oluvela ekushukumeni komhlaba. Izisombululo ziquka ukusebenzisa iintambo ezizaliswe yijeli okanye ezixhonyiweyo, ubunzulu obufanelekileyo, kwaye mhlawumbi nokusebenzisa umjelo kwiindawo ezinobungozi obukhulu nokuba kungcwatywa ngqo.

Linda, kodwa umsebenzisi ukhankanye "ukungcwaba ngqo", ngoko ke ukusebenzisa i-conduit kunokuphikisa oko. Mhlawumbi kwezinye iimeko, nokuba kukho iintambo zokungcwaba ngqo, kwiindawo ezinomngcipheko omkhulu, ukongeza i-conduit lukhuseleko olongezelelweyo. Okanye mhlawumbi uhlobo oluxhonyiweyo lwanele.

Ndifuna ukuqinisekisa ukuba zonke ezi ngongoma zigutyungelwe kwisikhokelo. Mandizihlele zibe ngamacandelo: Isishwankathelo, Iimpawu eziphambili, Iintlobo, Ukufakwa, Iingenelo, Iingxaki, Izicelo, Ukugcinwa, Imigangatho, Imiba Eqhelekileyo, Imibuzo Ebuzwa Rhoqo.

Linda, umzobo wokuqala umsebenzisi awunikileyo wawunamacandelo afana neempawu eziphambili, iintlobo zeentambo ze-Fiber Optic zokungcwaba ngqo, inkqubo yokufakela, iingenelo kunye neengxaki, izicelo, ukugcinwa kunye nobude bexesha, imigangatho kunye nokuthotyelwa kwemithetho, imiba eqhelekileyo kunye nezisombululo, imibuzo ebuzwa rhoqo.

Ndifanele ndilandele loo ndlela yokwakha. Mandiphinde ndijonge icandelo ngalinye kwakhona ukuze ndibone ukuba liphelele na.

Ezona mpawu: Ukhuseleko oluxhotyisiweyo, ukumelana namanzi, ukuqina, amalungu okuqina, ukumelana neempuku. Ngaba kukho into endiyiphosileyo? Mhlawumbi ukumelana ne-UV ukuba inxalenye yentambo iveziwe, kodwa ekubeni igqunyiwe, mhlawumbi akufuneki. Kodwa izinto zejakethi yangaphandle kufuneka zimelane neekhemikhali emhlabeni.

Iintlobo: Imowudi enye vs iimowudi ezininzi, ezixhotyisiweyo vs ezingaxhotyisiweyo, ityhubhu ekhululekileyo vs i-tight buffer, iintambo zeribhoni. Mhlawumbi chaza uhlobo ngalunye ngokufutshane.

Inkqubo yoFakelo: Amanyathelo afana nokucwangcisa indlela, ukufaka imisele, ukubeka intambo, ukuzalisa umqolo, iteyiphu yesilumkiso, ukuvavanya. Izinto ekufuneka ziqwalaselwe ngobunzulu, uhlobo lomhlaba, ukuphepha izinto ezikhoyo. Ukusebenzisa izixhobo ezifanelekileyo ezifana neekhuba okanye iitrenching.

Iingenelo vs Iingxaki: Ngaba ingabizi kakhulu, ifakelwa ngokukhawuleza, ihlala ixesha elide xa ithelekiswa nokuba isengozini yokonakala ukuba ayifakwanga kakuhle, ixabiso lokuqala liphezulu? Mhlawumbi xa lithelekiswa neentambo zomoya. Kwakhona, ingaba inzima ukuyilungisa kuba ingaphantsi komhlaba.

Izicelo: I-Telecom, i-intanethi, iindawo zasemaphandleni, ezomkhosi, izixhobo zikagesi, ezokhuseleko.

Ulondolozo: Ukuhlolwa rhoqo akunakwenzeka xa sele kufihliwe, ngoko ke mhlawumbi ukujonga ngovavanyo. Ukufumanisa ukulahleka kwesiginali, kusetyenziswa i-OTDR. Amaxwebhu endawo.

Imigangatho: Inqaku le-NEC Inqaku le-770, IEEE, ITU-T, iikhowudi zendawo.

Imiba Eqhelekileyo: Ukungena kwamanzi, umonakalo weempuku, ukuhamba komhlaba, ukumba ngengozi.

Izisombululo: Iintambo ezizaliswe yijeli, ezixhotyisiweyo, ubunzulu obufanelekileyo, iteyiphu yesilumkiso, amaxwebhu.

Imibuzo Ebuzwa Rhoqo: Ubunzulu? Ngokwesiqhelo yi-24-48 intshi. Ngaba kufuneka umjelo womoya? Hayi, kodwa unganyanzelekanga kwiindawo ezinobungozi obukhulu. Umahluko phakathi kwezixhobo zokulwa nezingaxhotyiswanga. Ungalungisa njani? Fumana impazamo, umbe, udibanise. Ubude bobomi? Iminyaka engama-20-25.

Linda, kwimpendulo yokuqala, umsebenzisi uquke wathi "Ngaba iintambo zokungcwaba ezithe ngqo zingasetyenziswa ngaphezulu komhlaba?" kwaye impendulo ayikhuthazwanga ngenxa yokunqongophala kokhuseleko lwe-UV. Linqaku elihle elo. Nangona zezomngcwabo, ukuzisebenzisa ngaphezulu komhlaba kunokufuna iijakethi ezimelana ne-UV.

Ndifuna ukuqinisekisa ukuba zonke ezi ngongoma zigutyungelwe. Kwakhona, mhlawumbi khankanya izinto ezisetyenzisiweyo kwijakethi, ezifana ne-polyethylene yokufuma kunye nokumelana neekhemikhali. Amalungu okuqina anokuba yi-fiberglass okanye intsimbi yokuqina kokutsalwa.

Enye into: Xa uthetha ngokufakela, mhlawumbi khankanya ukubaluleka kokuphepha ukugoba okubukhali, ukugcina irediyasi egobileyo encinci ukuthintela ukonakala kwimicu.

Kwicandelo lemigangatho, mhlawumbi kukho iikhowudi ezithile ze-NEC malunga nobunzulu bomngcwabo kunye neemfuno zokhuseleko.

Ukuvavanya, khankanya i-OTDR kunye novavanyo lokulahleka kokufakwa.

Kwiingxaki eziqhelekileyo, ukuguquguquka kobushushu okuchaphazela intambo? Okanye ngaba ubunzulu bokungcwaba banele ukunciphisa oko? Mhlawumbi kwiindawo ezibandayo kakhulu, ukunyuka kweqabaka kunokuba yingxaki, kufuna ukungcwaba okunzulu.

Kwakhona, kwimibuzo ebuzwa rhoqo, mhlawumbi kubandakanywa nokuba iintambo zokungcwaba ezithe ngqo zinokudityaniswa na, kunye nesidingo seendawo ezingangeni manzi xa zidityaniswa phantsi komhlaba.

Ndicinga ukuba oko kugubungela iinkalo ezininzi. Ngoku, hlela zonke ezi ngcinga zibe ngamacandelo acwangcisiweyo ngokwempendulo yokuqala, uqiniseke ukuba inxalenye nganye icacile kwaye iphelele.

Ngokusetyenziswa okukhulu kwe-FTTH Fiber eKhaya, amaziko edatha e-AI computing, i-5G fronthaul, i-indoor comprehensive wiring, i-FPV drone miniature communication kunye nokwakhiwa kohlaziyo lwangoku olubuthathaka kwihlabathi liphela, i-G.652D single-mode fiber yendabuko ihlushwa kukulahleka okukhulu kokugoba kunye nendawo encinci yocingo, nto leyo ethintela kakhulu ulwakhiwo lweenethiwekhi zonxibelelwano ze-optical ezikhawulezayo. Yenziwe yi-ITU-T, i-G.657 series bend-insensitive single-mode fiber yenzelwe ngokukodwa iikona ezijijekileyo, i-dense wiring kunye ne-micro-pipeline. Amanqanaba amathathu emveliso ephambili, i-G.657.A1 standard bend-resistant fiber, i-G.657.A2 ephuculweyo bend-resistant fiber kunye ne-G.657.B3 ultra-bend-insensitive fiber, isebenzisa iiprofayili ze-refractive index ezincediswa yi-trench-assisted refractive index, kwaye ibonisa umahluko olinganisiweyo kwi-minimum bending radius, i-mode field diameter kunye nokusebenza kwe-attenuation. Zigubungela iimfuno zemeko epheleleyo ukusuka kwi-wiring yasekhaya engabizi kakhulu ukuya kwi-ultra-compact special wiring.
