IFTTH ukuwisa iintambozisetyenziselwa ukwenza uqhagamshelo lwababhalisi ngokudibanisa iNdawo yokuSasaza ye-Optical kwi-Optical Telecommunications Outlet. Ngokuxhomekeke kwisicelo sabo, ezi ntambo ze-optical zihlelwa kwiindidi ezintathu eziphambili: amaconsi angaphandle, angaphakathi nangaphandle. Ngaloo ndlela, kuxhomekeke apho zisetyenziswa khona ngaphakathi kwesiseko se-FTTH, iintambo ze-optical drop cables kufuneka zihlangabezane nenani leenqobo zokusebenza.
Ngokungafaniyo namathontsi angaphakathi, angeniswa kuxinzelelo olumbalwa kakhulu emva kofakelo, iintambo zokulahla ngaphandle kufuneka zimelane neendidi ezininzi zemiqobo. Ezi ntambo zombane ziintambo zocingo ezibotshelelwe ecaleni kweepali zemfonomfono, ezisetyenziselwa ukusasazwa komhlaba kunye nofakelo kwimibhobho okanye ngokulula zandlalwe okanye zandiswe ecaleni kweefacade.
Ukwenza ukhetho olufanelekileyo malunga nesisombululo se-FTTH sokukhupha inethiwekhi yakho, kubalulekile ukuqwalasela:
1. Qonda iiMfuno: Ngaphambi kokukhetha intambo yokulahla, qonda iimfuno ezithile zeprojekthi yakho ye-FTTH. Qwalasela izinto ezifana nomgama phakathi kwendawo yokuhambisa kunye neendawo zomthengi, iimeko zokusingqongileyo, kunye nenani leentsinga ezifunekayo.
2. Uhlobo lweFayibha: Qinisekisa uhlobo lwefiber efunekayo kwisicelo sakho. Ifayibha yemowudi enye iqhele ukusetyenziselwa ukuhanjiswa komgama omde, ngelixa ifayibha yeendlela ezininzi ifanelekile kumgama omfutshane. Khetha uhlobo olufanelekileyo lwefayibha ngokusekwe kumgama kunye neemfuno zebhanwidth yenethiwekhi yakho.
3. Ulwakhiwo lweCable: Khetha intambo yokuwisa enolwakhiwo olufanelekileyo ukulungiselela ukufakela ngaphandle. Jonga iintambo ezenzelwe ukumelana neemeko zokusingqongileyo zangaphandle ezifana nokuvezwa kwe-UV, ukufuma, ukuhluka kobushushu, kunye noxinzelelo lomatshini. Ngokuqhelekileyo, iintambo zokulahla zangaphandle zine-sheath yangaphandle ehlala ixesha elide eyenziwe ngezinto ezifana ne-polyethylene (PE) okanye i-polyvinyl chloride (PVC).
4. Ukubalwa kweFayibha: Qwalasela inani leentsinga ezifunekayo kuthungelwano lwakho lwe-FTTH. Khetha intambo yokulahla enenani elaneleyo lemicu ukulungiselela iimfuno zangoku kwaye uvumele ukwandiswa kwexesha elizayo ukuba kuyimfuneko.
5. I-Bend Radius: Nika ingqalelo kwi-radius ye-bend encinci ye-cable cable. Qinisekisa ukuba intambo inokuhamba ngokukhuselekileyo kwiikona kunye nemiqobo ngaphandle kokudlula i-radius ye-bend echaziweyo, engakhokelela ekulahlekeni komqondiso okanye umonakalo kwifiber.
6. Ukuhambelana koQhagamshelwano: Jonga ukuhambelana kweziqhagamshelo zentambo yokulahla kunye neziqhagamshelo ezisetyenziswa kwisixhobo sakho sothungelwano kunye nezixhobo zezakhiwo zabathengi (CPE). Qinisekisa ukuba iziqhagamshelo zentambo ziyahambelana neziqhagamshelo zomgangatho woshishino ezifana ne-SC, LC, okanye i-ST.
7. Indlela yokuFakela: Qwalasela indlela yokufakela intambo yokulahla. Khetha phakathi kwe-eriyali, ukungcwatywa, okanye ukufakela phantsi komhlaba ngokusekelwe kwiimfuno zakho ezithile kunye nemimiselo yendawo. Khetha intambo yokulahla efanele indlela yakho yofakelo oyikhethileyo.
8. Umgangatho kunye nokuthembeka: Beka phambili umgangatho kunye nokuthembeka xa ukhetha intambo yokulahla. Khetha iintambo kubavelisi abathembekileyo abanerekhodi yokuvelisa iimveliso zefiber optic ezikumgangatho ophezulu. Khangela iintambo ezihambelana nemigangatho yoshishino efanelekileyo kunye neziqinisekiso.
9. Ukuqwalaselwa kweendleko: Nangona ixabiso liyinto ebalulekileyo, beka phambili ukusebenza kunye nokuthembeka ngaphezu kwexabiso xa ukhetha intambo yokulahla. Utyalo-mali kwiintambo ezikumgangatho ophezulu, ezihlala zihlala zinokunceda ukukhusela iindleko zokugcinwa kwexesha elizayo kunye nokuqinisekisa ukusebenza kwenethiwekhi ixesha elide.
10. Uthethwano kunye nobuGcisa: Ukuba akuqinisekanga malunga nokuba yeyiphi intambo yokulahla omawuyikhethe, cinga ukubonisana neengcali zefiber optic okanye iinjineli zenethiwekhi ezinokukunika isikhokelo ngokusekelwe kwiimfuno zakho ezithile kunye nemiqobo yeprojekthi.
Ngokuqwalasela le miba kunye nokwenza uphando olucokisekileyo, unokukhetha eyona ifanelekileyoFTTH intambo yokulahla ifayibha yangaphandlekwiprojekthi yakho, ukuqinisekisa ukusebenza okuthembekileyo kunye nokuqina kwiindawo ezingaphandle.
