TheFTTH theola likhoeleli sebelisoa ho nolofalletsa likhokahano tsa ba ngolisitseng ka ho hokahanya Optical Distribution Point ho Optical Telecommunications Outlet. Ho itšetlehile ka kopo ea bona, lithapo tsena tsa optical li arotsoe ka lihlopha tse tharo tse kholo: marotholi a ka ntle, a ka hare le a ka ntle. Kahoo, ho itšetlehile ka hore na li sebelisoa hokae ka har'a lisebelisoa tsa FTTH, lithapo tsa optical drops li tlameha ho finyella litekanyetso tse ngata tsa tshebetso.
Ho fapana le marotholi a ka hare, a romelloang khatellong e fokolang haholo ka mor'a ho kenngoa, lithapo tsa ho theoha ka ntle li tlameha ho mamella mefuta e mengata ea lithibelo. Lithapo tsena tsa optical ke lithapo tsa mehala tse hokelletsoeng ka thoko ho lipalo tsa mohala, tse sebelisetsoang ho tsamaisa le ho kenya likotopong kapa tse atolositsoeng kapa ho atolosoa haufi le lifensetere.
Ho etsa khetho e nepahetseng ho latela tharollo ea FTTH cabling bakeng sa ho phatlalatsoa ha marang-rang a hau, ho bohlokoa ho nahana ka:
1. Utloisisa Litlhoko: Pele u khetha thapo e theohang, utloisisa litlhoko tse khethehileng tsa projeke ea hau ea FTTH. Nahana ka lintlha tse kang sebaka se pakeng tsa sebaka sa kabo le sebaka sa bareki, maemo a tikoloho, le palo ea likhoele tse hlokahalang.
2. Mofuta oa Fiber: Fumana mofuta oa fiber e hlokahalang bakeng sa kopo ea hau. Fiber ea mofuta o le mong hangata e sebelisoa bakeng sa phetisetso ea sebaka se selelele, athe fiber ea mefuta e mengata e loketse sebaka se khuts'oane. Khetha mofuta o nepahetseng oa faeba ho latela bohole le litlhoko tsa bandwidth tsa marang-rang a hau.
3. Kaho ea Cable: Khetha thapo e theohang e nang le kaho e nepahetseng bakeng sa ho kenya kantle. Batla likhoele tse etselitsoeng ho mamella maemo a kantle a tikoloho joalo ka ho pepeseha ha UV, mongobo, ho fapana ha mocheso le khatello ea mochini. Ka tloaelo, likhoele tse ka ntle li na le sheath e tšoarellang ea kantle e entsoeng ka thepa e kang polyethylene (PE) kapa polyvinyl chloride (PVC).
4. Fiber Count: Nahana ka palo ea likhoele tse hlokehang bakeng sa netweke ea hau ea FTTH. Khetha thapo e theohang e nang le palo e lekaneng ea likhoele ho amohela litlhoko tsa hajoale le ho lumella katoloso ea nako e tlang ha ho hlokahala.
5. Bend Radius: Ela hloko sebaka se fokolang sa ho kobeha ha mohala o theoha. Netefatsa hore thapo e ka tsamaisoa ka mokhoa o sireletsehileng likhutlong le litšitiso ntle le ho feta sebaka se boletsoeng se kobehileng, se ka lebisang tahlehelong ea mats'oao kapa tšenyo ea fiber.
6. Tšebelisano ea Sehokelo: Lekola ho tsamaellana ha lihokelo tsa thapo tse theohang le likhokahanyo tse sebelisoang thepa ea netweke ea hau le lisebelisoa tsa meaho ea bareki (CPE). Netefatsa hore likhokahanyo tsa thapo li lumellana le lihokelo tse tloaelehileng tsa indasteri tse kang SC, LC, kapa ST.
7. Mokhoa oa ho kenya: Nahana ka mokhoa oa ho kenya mohala oa ho theola. Khetha pakeng tsa ho kenngoa ka sefofane, ho patoa, kapa ka tlas'a lefatše ho latela litlhoko tsa hau tse khethehileng le melao ea lehae. Khetha thapo e theohang e loketseng mokhoa oo u o khethileng oa ho instola.
8. Boleng le Botšepehi: Etelletsa pele boleng le botšepehi ha u khetha mohala o theoha. Khetha lithapo ho tsoa ho bahlahisi ba tsebahalang ba nang le rekoto ea ho hlahisa lihlahisoa tsa boleng bo holimo tsa fiber optic. Sheba lithapo tse tsamaellanang le maemo le litifikeiti tsa indasteri tse amehang.
9. Ho Nahana ka Litšenyehelo: Le hoja litšenyehelo e le ntlha ea bohlokoa, etelletsa pele ts'ebetso le ho tšepahala ho feta theko ha u khetha mohala o theoha. Ho kenya chelete ka lithapo tsa boleng bo phahameng, tse tšoarellang ho ka thusa ho thibela litšenyehelo tsa tlhokomelo ea nako e tlang le ho netefatsa ts'ebetso ea nako e telele ea marang-rang.
10. Therisano le Boitseanape: Haeba o sa tsebe hantle hore na o khetha thapo efe ea drop drop, nahana ka ho buisana le litsebi tsa fiber optic kapa lienjineri tsa marang-rang tse ka fanang ka tataiso ho latela litlhoko tsa hau tse ikhethileng le lithibelo tsa projeke.
Ka ho nahana ka lintlha tsena le ho etsa lipatlisiso ka botlalo, u ka khetha tse loketseng ka ho fetisisaFTTH thapo e theohang ka ntle ea faebabakeng sa projeke ea hau, ho netefatsa ts'ebetso e ts'epahalang le ho tšoarella maemong a kantle.
