Njengoko sonke sisazi ukuba umbane kukukhutshwa kombane we-atmospheric obangelwa kukwakhiwa kweentlawulo ezahlukeneyo ngaphakathi kwelifu.Isiphumo soku kukukhululwa kwamandla ngequbuliso okubangela ukudangala okuqaqambileyo okwahlukileyo, kulandelwa kukubetha kwendudumo.
Ngokomzekelo, ayiyi kuchaphazela kuphela zonke iziteshi zefayibha ze-DWDM ngokugqabhuka okufutshane, kodwa zichaphazela izikhokelo zothumelo ngaxeshanye ngokophando oluninzi.Iya kubangela nomlilo xa kukho ukukhutshwa kombane okuphezulu.Nangona imiqondiso kwiintambo zefayibha ziyimiqondiso ye-optical, uninzi lweentambo zangaphandle zangaphandle zisebenzisa ii-cores eziqinisiweyo okanye iintambo ze-armored optical zilula ukuba zonakaliswe phantsi kombane ngenxa yentsimbi ekhuselayo ngaphakathi kwentambo.Ngoko ke, kubalulekile ukwakha inkqubo yokukhusela umbane kwiintambo zokukhusela ezikhuselayo.

Ukukhuselwa kombane kwimigca yentambo yentambo ethe tye: ①Imowudi yokumisa eofisini, iindawo zentsimbi kwintambo yokukhanya kufuneka ziqhagamshelwe kumalungu, ukuze undoqo wokuqinisa, umaleko wobungqina bokufuma kunye nomaleko wesikrweqe wecandelo lokuhanjiswa kwe-optical. intambo igcinwa kwimo eqhagamshelweyo.②Ngokwemigaqo ye-YDJ14-91, umaleko wobungqina bokufuma, umaleko wesikrweqe kunye nondoqo wokuqinisa kwindawo edibeneyo yentambo ye-optical kufuneka iqhawulwe ngombane, kwaye ayisekelwanga, kwaye ikhuselwe emhlabeni, enokuthintela ukuqokelelana. umbane owenziweyo ngoku kwintambo yokukhanya.Iyakwazi ukuphepha ukuba umbane wangoku emhlabeni ungeniswa kwikhebula le-optical ngesixhobo sokumisa ngenxa yokwahlukana kwe-impedance yocingo lokukhusela umbane kunye necandelo lensimbi yentambo ye-optical emhlabeni.

Kwiintambo zamehlo ezingaphezulu: iingcingo ezixhonywe phezulu kufuneka zidityaniswe ngombane kwaye zibekwe phantsi qho nge-2km.Xa uphantsi komhlaba, unokusekwa ngokuthe ngqo okanye usekelwe ngesixhobo esifanelekileyo sokukhusela ukutshiza.Ngale ndlela, ucingo lokumiswa lunempembelelo yokukhusela yocingo olungaphezulu.

Emva kweintambo yokukhanyaingena kwi-terminal box, ibhokisi ye-terminal kufuneka isekelwe.Emva kokuba umbane wombane ungene kwi-metal layer ye-optical cable, isiseko sebhokisi ye-terminal sinokukhulula ngokukhawuleza umbane kwaye udlale indima yokukhusela.Intambo ye-optical engcwatywe ngokuthe ngqo inomaleko wesikrweqe kunye nesiseko esomeleziweyo, kwaye i-sheath yangaphandle yi-PE (polyethylene) sheath, enokuthintela ngokufanelekileyo ukubola kunye nokulunywa kweempuku.
