Intambo ye-optical engcwatywe ngokuthe ngqo ixhotywe ngetape yensimbi okanye ucingo lwentsimbi ngaphandle, kwaye ingcwatywe ngokuthe ngqo emhlabeni.Ifuna ukusebenza kokumelana nomonakalo wangaphandle womatshini kunye nokuthintela ukubola komhlaba.Izakhiwo zesheath ezahlukeneyo kufuneka zikhethwe ngokwendawo ezahlukeneyo zokusebenzisa kunye neemeko.Ngokomzekelo, kwiindawo ezinezinambuzane kunye neempuku, kufuneka kukhethwe intambo ye-optical ene-sheath ekhusela izinambuzane kunye neentonga.Ngokuxhomekeke kumgangatho womhlaba kunye nokusingqongileyo, ubunzulu bentambo yokukhanya engcwatywe ngaphantsi komhlaba ngokuqhelekileyo buphakathi kwe-0.8m kunye ne-1.2m.Xa ubeka, kufuneka kuthathelwe ingqalelo ukugcina uxinzelelo lwefayibha ngaphakathi kwemida evumelekileyo.
Umngcwabo othe ngqo kufuneka uhlangabezane nezi mfuno zilandelayo:
1. Gwema iindawo ezine-asidi eqinile kunye ne-alkali corrosion okanye i-corrosion yekhemikhali enzima;xa kungekho milinganiselo yokukhusela ehambelanayo, gwema iindawo zomonakalo we-termite kunye neendawo ezichatshazelwa yimithombo yobushushu okanye iindawo ezonakaliswe lula ngamandla angaphandle.
2. Intambo ye-optical kufuneka ibekwe emseleni, kwaye indawo ejikelezileyo yekhebula ye-optical kufuneka igqunywe ngomhlaba othambileyo okanye umaleko wesanti kunye nobukhulu obungekho ngaphantsi kwe-100mm.
3. Kulo lonke ubude bekhebula le-optical, ipleyiti ekhuselayo enobubanzi obungekho ngaphantsi kwe-50mm kumacala omabini e-optical cable kufuneka igutyungelwe, kwaye iplate yokukhusela kufuneka yenziwe ngekhonkrithi.
4. Indawo yokubeka ikwiindawo ezinokwembiwa rhoqo ezifana neendlela zokungena ezidolophini, ezinokubekwa ngamabhanti atsala amehlo kwibhodi yokhuseleko.
5. Kwindawo yokubeka kwiidolophu okanye kwindawo evulekileyo, kwisithuba somgca othe tye malunga ne-100mm ecaleni kwendlela yentambo ye-optical, kwindawo yokujika okanye inxalenye edibeneyo, iimpawu ezicacileyo zokuqhelaniswa okanye izibonda kufuneka zimiswe.
6. Xa ubeka kwiindawo zomhlaba ezingenamkhenkce, i-sheath yekhebula ye-optical kwisiseko sesakhiwo esingaphantsi komhlaba asiyi kuba ngaphantsi kwe-0.3m, kwaye ubunzulu be-sheath ye-cable optical emhlabeni abuyi kuba ngaphantsi kwe-0.7m;xa ibekwe endleleni okanye umhlaba olinyiweyo, kufuneka ifakwe ngokufanelekileyo, kwaye ingabi ngaphantsi kwe-1m.
7. Xa ubeka kwindawo yomhlaba onqabileyo, kufuneka ungcwatywe ngaphantsi komgangatho womhlaba onqabileyo.Xa ingakwazi ukungcwatywa nzulu, inokungcwatywa kumhlaba owomileyo onomkhenkce okanye uzalise umhlaba ngokuhambisa amanzi alungileyo, kunye namanye amanyathelo okuthintela umonakalo kwintambo ye-optical nayo ingathathwa..
8. Xa imigca yentambo yokukhanya engcwatywe ngokuthe ngqo inqumla koololiwe, uhola wendlela okanye izitrato, imibhobho ekhuselayo kufuneka inxitywe, kwaye umda wokhuseleko kufuneka udlule i-roadbed, macala omabini omgaqo wesitrato kunye necala lomsele wokuhambisa amanzi ngaphezulu kwe-0.5m.
9. Xa ikhebula le-optical elingcwatywe ngokuthe ngqo lingeniswa kwisakhiwo, ityhubhu yokukhusela kufuneka ibekwe kwi-slope hole, kwaye umbhobho kufuneka uvalwe ngamanzi.
10. Umgama ocacileyo phakathi kokudityaniswa kwentambo ye-optical engcwatywe ngokuthe ngqo kunye nekhebula le-optical elikufutshane aliyi kuba ngaphantsi kwe-0.25m;izikhundla ezidibeneyo ze-parallel optical cables kufuneka zidibanise ukusuka komnye nomnye, kwaye umgama ocacileyo awuyi kuba ngaphantsi kwe-0.5m;indawo edibeneyo kwindawo ye-slope kufuneka ibe tye;kwiisekethe ezibalulekileyo Kucetyiswa ukuba ushiye indlela esecaleni yokubeka intambo ye-optical kwicandelo lendawo ukusuka malunga ne-1000mm kumacala omabini e-optical cable joint.
