Umphezulu OPGW Ikhebhula kuMmandla woThutho weAluminiyam ehonjiswe ngentsimbi yeTube
Khuphela IINKCUKACHA ZOLUDLO
Isicelo
I-OPGW Cable engaphezulu ilungele ukufakwa kwiintambo zothumelo kwaye inomsebenzi ombini wocingo oluphantsi (olwenzelwe ukuba luthathe indawo yeengcingo zemveli ezimileyo okanye ezikhuselayo) kunye neengcingo zonxibelelwano.
I-OPGW iqhuba imisinga emfutshane yesekethe kwaye ibonelela ngokhuseleko ekubetheni kombane ngelixa "ikhusela" abaqhubi, ngelixa ibonelela ngendlela yonxibelelwano ngonxibelelwano lwangaphakathi kunye nomntu wesithathu.
I-OPGW kufuneka ikwazi ukumelana noxinzelelo lomatshini kunye nokusingqongileyo olubekwe kwiintambo eziphezulu (ezifana nezo zibangelwa ngumoya okanye umkhenkce).I-OPGW kufuneka kwakhona ikwazi ukuphatha iimpazamo zombane kumgca wothumelo ngokubonelela indlela eya emhlabeni ngelixa ikhusela umonakalo kwimicu ethambileyo ye-optical ngaphakathi kwentambo.
Ukwakhiwa
Intambo ye-OPGW inezakhiwo ezimbini:
1. Uhlobo lwetyhubhu evulekileyo ephakathi
Iintsinga zibekwe ngokukhululekileyo kwindawo evaliweyo nenganyangekiyo emanzini, ityhubhu ye-aluminiyam egcwele ijeli yokuthintela amanzi.Le bhubhu inika ukhuseleko kwifiber ngexesha lofakelo kunye nokusebenza phantsi kweemeko ezinzima zokusingqongileyo.I-tube yensimbi engenasici inokuthi ibe yintsimbi ye-aluminium-clad ngokuxhomekeke kwiimfuno zobunjineli.Ityhubhu ye-stainless optical ibekwe kumbindi wentambo ekhuselweyo ngamaleko omnye okanye amaninzi entsimbi ene-aluminiyam, iingcingo ze-aluminiyam, okanye iingcingo zentsimbi.Iingcingo zetsimbi zinika amandla omatshini wokumelana nofakelo olunzima kunye neemeko zokusebenza, ngelixa ufezekisa i-conductivity ukulawula ukunyuka kweqondo lokushisa ngexesha leemeko ezimfutshane.
Ifiber nganye ebonakalayo ibonakala ngokucacileyo kusetyenziswa inkqubo yokuchonga ifayibha equka umbala kunye nenani lamanqaku eringi kuyo.Olu lwakhiwo ludityanisiweyo lubonisa amandla omatshini aphezulu kunye nempazamo yangoku yokulinganisa ngaphakathi kwedayamitha encinci.Idayamitha encinci ikwakhokelela ekusebenzeni okugqwesileyo koxinzelelo lwe-sag.
2.Udidi lwetyhubhu ekhululekileyo eMulti
Iintsinga zibekwe ngokukhululekileyo kwityhubhu yentsimbi engenamanzi etywiniweyo nenganyangekiyo ezaliswe yijeli yokuthintela amanzi.Iityhubhu ezimbini okanye ezintathu zentsimbi engenastainless zixinzelelwe nge-helically kumaleko angaphakathi wentambo ene-multiple-layer cable.Uhlobo lwetyhubhu ekhululekileyo yenzelwe ubukhulu becala imfuneko yefayibha ephezulu kakhulu ngaphezulu kwe-48 kunye nenani eliphezulu lefiber count efikelela kwi-144.
I-fiber ebonakalayo yenziwe nge-silica ephezulu ecocekileyo kunye ne-germanium doped silica.Imathiriyeli ye-acrylate enyangekayo ye-UV isetyenziswa ngaphezulu kwefiber cladding njengefiber ebonakalayo ekhuselayo.Iinkcukacha zedatha yokusebenza kwefiber optical zibonisiwe kolu luhlu lulandelayo.
Ifayibha ye-Optical isebenzisa isixhobo esikhethekileyo sokusonta esilawule ngempumelelo ixabiso le-PMD, kwaye iqinisekisa ukuba inokugcina izinzile kwicabling.
