Ikhebula le-OPGW (Optical Ground Wire) uhlobo olukhethekile lwekhebula olusetshenziswa emigqeni yokudlulisa amandla ephezu. Luqukethe kokubili imicu ye-optical yokudlulisa idatha kanye nomqhubi ojwayelekile wokudlulisa amandla kagesi. Imicu ye-optical engaphakathi kwekhebula le-OPGW ivame ukumbozwa ngesendlalelo esivikelayo ukuze ivikeleke ezicini zemvelo ezifana nomswakama, ukushintshashintsha kwezinga lokushisa, kanye nomonakalo ongokwenyama.

Ikhebula le-OPGW linikeza izinzuzo eziningana:

Ukusebenza Okubili: Ikhebula le-OPGW lisebenza ngenhloso ekabili yokuphatha amandla kagesi nokudlulisa idatha ngemicu ye-optical, ngaleyo ndlela kunciphisa isidingo sengqalasizinda ehlukile yokuxhumana.

Ukuthembeka: Ngokuhlanganisa imicu ye-optical ohlelweni lokudlulisa amandla, ikhebula le-OPGW linikeza indlela yokuxhumana ethembekile ngezinjongo zokuqapha nokulawula.

Ukuphepha: Izintambo ze-OPGW zenzelwe ukumelana nezimo ezinzima zezintambo zokudlulisa amandla eziphezulu, ukuqinisekisa ukuphepha nokuthembeka kokuxhumana kanye nokudlulisa amandla.

I-bandwidth ephezulu: Imicu yokubona esetshenziswa ezintanjeni ze-OPGW inikeza amandla aphezulu okudlulisa idatha, okuvumela ukudluliswa kwedatha eningi emabangeni amade ngokulahlekelwa okuncane kwesiginali.

Isivikelo: Umklamo wekhebula le-OPGW uhlanganisa izendlalelo ezivikelayo ukuvikela imicu ye-optical ezicini zemvelo kanye nokucindezeleka kwemishini, okuqinisekisa ukuthi ihlala isikhathi eside futhi inokwethenjelwa.

Ukufakwa Kwekhebula le-OPGW

Sekukonke, ikhebula le-OPGW lidlala indima ebalulekile kumanethiwekhi okudlulisa amandla esimanje ngokwenza kube lula ukuxhumana nokuqapha okusebenzayo ngenkathi kuqinisekiswa ukudluliswa kwamandla kagesi okuthembekile.

Ukufakwa kwe-OPGW (Optical Ground Wire) kuvame ukuhilela izinyathelo eziningana ukuqinisekisa ukuhlanganiswa okufanele emigqeni yokudlulisa amandla ephezulu. Nasi isifinyezo esijwayelekile senqubo yokufaka:

Ukulungiselela: Ngaphambi kokuba kuqale ukufakwa, ukuhlela nokulungiselela okuphelele kubalulekile. Lokhu kuhlanganisa ukuhlola umzila womugqa wokudlulisa ugesi, ukunquma ubude obudingekayo bekhebula le-OPGW, nokuqinisekisa ukuthi yonke imishini nezinto ezidingekayo ziyatholakala.

Ukuhlanza Nokuhlola: Indawo ezungeze umugqa wokudlulisa ugesi isusiwe kunoma yiziphi izithiyo noma izitshalo ezingase ziphazamise inqubo yokufaka. Umugqa wokudlulisa ugesi ngokwawo uyahlolwa ukuqinisekisa ukuthi uqinile ngokwesakhiwo futhi uyakwazi ukusekela isisindo esengeziwe sekhebula le-OPGW.

Ukufakwa Kwehadiwe: Ihadiwe ekhethekile, njengezibambo zokumiswa, ama-damper okudlidliza, namabhokisi e-splice, ifakiwe eceleni komugqa wokudlulisa amandla ukuze isekele futhi ivikele ikhebula le-OPGW. Lezi zingxenye zehadiwe zivame ukuklanywa ukuze zibhekane nokucindezeleka komshini kanye nezimo zemvelo ezikhona ezindaweni zokudlulisa eziphezulu.

Ukuhlanganiswa kwekhebula le-OPGW: Ikhebula le-OPGW liboshwe ngokucophelela ubude bomugqa wokudlulisa amandla kusetshenziswa imishini ekhethekile efana nama-tensioner, imishini yokudonsa, kanye namadivayisi okuqapha ukucindezeleka. Ikhebula kumele lifakwe ngokucindezeleka okufanele ukuqinisekisa ubuqotho nokusebenza kwalo.

Ukuqedwa Nokuhlukaniswa: Uma ikhebula le-OPGW selikhona, liyavalwa ekugcineni ngakunye komugqa wokudlulisela kusetshenziswa ukuvalwa kwe-splice noma amabhokisi okuqeda. Imicu ye-optical ngaphakathi kwekhebula ingadinga futhi ukuhlanganiswa ndawonye ukuze kudalwe izindlela zokuxhumana eziqhubekayo ngobude bomugqa.

Ukuhlolwa Nokugunyazwa: Ngemva kokuthi ukufakwa sekuqediwe, kwenziwa ukuhlolwa okuphelele kwekhebula le-OPGW kanye nehadiwe ehlobene nalo ukuqinisekisa ukusebenza kwalo kanye nokusebenza kwalo. Lokhu kungafaka phakathi ukuhlolwa kokuqhuba kukagesi, ukulahleka kwesignali yokukhanya, ubuqotho bomshini, kanye nokuthembeka kokuxhumana.

Imibhalo kanye Nokugcinwa: Imibhalo eningiliziwe yenqubo yokufaka, okuhlanganisa imidwebo eyakhiwe kanye nemiphumela yokuhlolwa, ihlanganiswa ukuze isetshenziswe esikhathini esizayo. Ukugcinwa njalo nokuhlolwa kwekhebula le-OPGW nakho kubalulekile ukuqinisekisa ukuthembeka nokusebenza kwalo okuqhubekayo.

Sekukonke, ukufakwa kwekhebula le-OPGW kudinga ukuhlela ngokucophelela, abasebenzi abanamakhono, kanye nemishini ekhethekile ukuqinisekisa ukuhlanganiswa okufanele emigqeni yokudlulisa amandla ephezulu. Ukulandela izinqubo ezimisiwe kanye nemikhuba emihle kubalulekile ukuze kwandiswe ukuthembeka kanye nobude besikhathi bengqalasizinda efakiwe.
