Ikhebhula ye-Eletroniki- eDityanisiweyo ngaphezulu kocingo oluGwayiza oluneMicu yokubona (OPGW) iWasin Fujikura
intshayelelo
► I-OPGW okanye eyaziwa ngokuba yi-Optical Ground Wire luhlobo lolwakhiwo lwekheyibhile edityanisiweyo yothumelo lwamehlo kunye nocingo olungaphezulu komhlaba oluthunyelwa ngamandla. Isetyenziswa kwiintambo zothumelo lwamandla zombini njengentambo yefiber optical kunye nocingo olungaphezulu komhlaba olunokubonelela ngokhuseleko lokubetha kombane kunye nokuqhuba umsinga omfutshane.
► I-OPGW iquka i-stainless steel tube optical unit, i-aluminium cladding steel wire, i-aluminium alloy wire. Inesakhiwo setyhubhu yentsimbi ephakathi kunye nesakhiwo se-stranding. Sinokuyila isakhiwo ngokwemeko eyahlukeneyo yokusingqongileyo kunye neemfuno zomthengi.
Uphawu
► Iyunithi ye-fiber optical yensimbi engenasici yetyhubhu evulekileyo esembindini okanye isakhelo sokuqhina
► I-aluminiyam i-alloy wire kunye ne-aluminiyam enentsimbi yentsimbi enezixhobo
► Utyatyiswe ngegrisi enqanda ukubola phakathi kweeleya
► I-OPGW inokuxhasa umthwalo onzima kunye nofakelo olude lwe-span
► I-OPGW inokuhlangabezana nemfuno yocingo oluphantsi lomatshini kunye nombane ngokulungelelanisa ubungakanani bentsimbi kunye ne-aluminiyam.
► Kulula ukuvelisa iinkcukacha ezifanayo zocingo olusemhlabeni olukhoyo lunokuthatha indawo yocingo olusemhlabeni olukhoyo.
► I-OPGW inika iiNkampani zaMandla ithuba lokusebenzisa iinqaba zazo ngeenjongo ezizezinye kunokuhambisa umbane. Bona kutyalo-mali oluncinci banokubonelela ngoQhagamshelwano lweZakhono eziPhezulu kakhulu kwicandelo leTelecom.
Iipropati zesicelo
► Intambo ye-OPGW iyaqhutywa, okanye ifakwe phakathi kwemiphezulu yeepali zombane ezinevoltheji ephezulu, intsimbi, amaplanga, okanye iipali zekhonkrithi ezinezifakelo ezifanelekileyo nezincamatheleyo. Inxalenye yentambo yentambo, kulo mzekelo intsimbi isebenzela ukudibanisa iinqaba ezikufutshane nomhlaba, kwaye ikhusela abaqhubi be-high-voltage ekubetheni kombane.
► I-OPGW inophawu lokuba akukho siphumo sokunyuswa kwamandla ombane aphezulu kwidatha ehanjiswa ngeeFibers. Yiyo loo nto olu phawu lweFayibha luthatyathelwa ithuba lokuhambisa idatha kunye nemigca yokuhambisa amandla aphezulu.
► Iintsinga zamehlo ngaphakathi kwentambo zinokusetyenziselwa ukuhanjiswa kwedatha ngesantya esiphezulu. Umbane wombane unokusebenzisa intambo ye-fiber optics kwi-SCADA yayo, inkqubo yokukhusela kunye nokulawula umgca wokuhambisa, i-VOIP, kunye nezinye iinjongo zonxibelelwano. Kwiimeko ezinjalo, banokugcina kwiindleko zokufakela iingcingo zentsimbi ezongezelelweyo ezisebenza njengendawo yomhlaba okanye i-shield ingcingo kwimigca yazo. Basenokuqeshisa okanye bathengiselwe amaqela esithathu ukuba asebenze njengonxibelelwano olunesantya esiphezulu lwefiber optic phakathi kwezixeko, kunye nolunye uthungelwano.
