Lipotso tse botsoang khafetsa ka likhoele tsa fiber optic:
1, Cable ea ho theola fiber e bitsa bokae?
Ka tloaelo, theko ka 'ngoe ea fiber optic cable e tloha ho $30 ho ea ho $1000, ho itšetlehile ka mofuta le bongata ba likhoele: G657A1/G657A2/G652D/OM2/OM3/OM4/OM5, thepa ea baki PVC/LSZH/PE, bolelele, le moralo oa Sebopeho. le lintlha tse ling li ama litheko tsa likhoele tse theohang.
2. Thatolikhoele tsa fiber opticho senyeha?
Lithapo tsa fiber optic hangata li hlalosoa e le tse senyehang habonolo, joalo ka khalase.Ehlile, fiber ke khalase.Lithapo tsa khalase tse likhoeleng tsa fiber optic lia senyeha habonolo, ’me le hoja likhoele tsa fiber optic li etselitsoe ho sireletsa likhoele, li kotsing ea ho senyeha ho feta terata ea koporo.Tšenyo e atileng haholo ke ho robeha ha fiber, eo ho leng thata ho e lemoha.Leha ho le joalo, likhoele li ka boela tsa robeha ka lebaka la tsitsipano e feteletseng nakong ea ho hula kapa ho robeha.Na likhoele tsa fiber optic li tla senyeha Lithapo tsa fiber optic hangata li senyeha ka e 'ngoe ea litsela tse peli:
• Lithapo tse entsoeng esale pele tsa fiber optic li ka senya likhokahano haeba ho sebelisoa tsitsipano e feteletseng nakong ea ho kenya.Sena se ka etsahala ha likhoele tse telele tsa fiber optic li fetisoa ka likotopo tse thata kapa likotopong kapa ha likhoele tsa fiber optic li qaoa.
• Mohala oa fiber optic o ile oa khaoloa kapa oa robeha nakong ea ts'ebetso 'me o ne o hloka ho aroloa hape ho hokahanya hape.
3, Ke tseba joang haeba thapo ea ka ea faeba e senyehile?
Haeba u ka bona mabone a mangata a khubelu, sehokelo se tšabeha 'me se lokela ho nkeloa sebaka.Sehokelo se setle haeba u sheba pheletsong e 'ngoe 'me u bona leseli le tsoang ho fiber feela.Ha se hantle haeba ferrule kaofela e benya.OTDR e ka tseba hore na sehokelo se senyehile haeba thapo e le telele ka ho lekaneng.
4, Mokhoa oa ho khetha likhoele tsa Fiber Optic tse thehiloeng ho Bend Radius?
Radius e kobehang ea thapo ea fiber optic e bohlokoa bakeng sa ho kenya.Lintlha tse amang radius e nyane ea thapo ea fiber optic li kenyelletsa botenya ba baki ea kantle, ho hlaka ha thepa, le bophara ba mantlha.

6, Lithapo tsa faeba li hloka ho nkeloa sebaka hangata hakae?
Hoo e ka bang lilemo tse 30, bakeng sa likhoele tsa fiber tse kentsoeng hantle, monyetla oa ho hloleha ka nako e joalo e ka ba 1 ho tse 100,000.
Ha ho bapisoa, monyetla oa ho kenella ha batho (joalo ka ho cheka) ho senya fiber ke hoo e ka bang 1 ho 1,000 ka nako e le 'ngoe.Ka hona, tlas'a maemo a amohelehang, fiber ea boleng bo phahameng e nang le theknoloji e ntle le ho kenya ka hloko e lokela ho tšepahala haholo - hafeela e sa khathatsehe.
7, Na boemo ba leholimo bo batang bo tla ama likhoele tsa fiber optic?
Ha mocheso o theohela ka tlas’a ntlha ea khoamo ’me metsi a hoama, leqhoa le hlaha ho pota-potile likhoele - e leng se etsang hore likhoele li holofale le ho kobeha.Sena se fokotsa lets'oao ka fiber, bonyane ho fokotsa bandwidth empa ho ka etsahala ho emisa phetisetso ea data ka botlalo.
8, Ke mathata afe ho a latelang a tla baka tahlehelo ea lets'oao?
Lisosa tse atileng haholo tsa ho hloleha ha fiber:
• Ho robeha ha fiber ka lebaka la khatello ea kelello ea 'mele kapa ho kobeha ho feteletseng
• Matla a ho fetisa a sa lekaneng
• Ho lahleheloa ke mats'oao ho feteletseng ka lebaka la lithapo tse telele tsa cable

• Khokahano e fosahetseng ea faeba ho patch panel kapa tereing ea splice
Hangata, haeba khokahanyo e hlōleha ka ho feletseng, ke hobane thapo e robehile.Leha ho le joalo, haeba khokahanyo e le ka nakoana, ho na le mabaka a 'maloa a ka bang teng:
• Thibelo ea thapo e kanna ea ba holimo haholo ka lebaka la likhokahano tsa boleng bo tlase kapa lihokelo tse ngata haholo.
• Lerōle, likhatiso tsa menoana, mengoapo le mongobo li ka silafatsa lihokelo.
• Matla a transmitter a tlase.
• Lihokelo tse fosahetseng ka oteropo ea likhoele.
9, Mohala o tebile hakae?
Botebo ba Cable: Botebo boo ho ka behoang lithapo tse epetsoeng ho bona bo tla fapana ho latela maemo a sebaka, joalo ka "mehala ea leqhoa" (botebo boo mobu o hoamang selemo le selemo).Ho khothaletsoa ho epela likhoele tsa fiber optic sebakeng se tebileng / se koahelang bonyane lisenthimithara tse 30 (77 cm).
10, Mokhoa oa ho fumana likhoele tsa optical tse patiloeng?
Tsela e molemo ka ho fetisisa ea ho fumana thapo ea fiber optic ke ho kenya palo ea cable ka har'a kotopo, ebe u sebelisa sesebelisoa sa ho fumana sebaka sa EMI ho hokahanya ka ho toba ho pole ea cable le ho latela letšoao, leo, ha le etsoa ka nepo, le ka fanang ka sebaka se nepahetseng haholo.
11. Na lisebelisoa tsa tšepe li ka fumana likhoele tsa optical?
Joalo ka ha bohle re tseba, litšenyehelo tsa ho senya lithapo tsa fiber optic li phahame.Hangata ba jara meroalo e boima ea puisano.Hoa hlokahala ho fumana sebaka sa bona se nepahetseng.
Ka bomalimabe, ba na le phephetso ea ho fumana sebaka ka lisebelisoa tsa fatše.Ha se tšepe 'me ha li khone ho sebelisa tšepe e nang le mochine oa ho fumana mohala.Litaba tse monate ke hore hangata li kopane 'me li ka ba le likarolo tse ka ntle.Ka linako tse ling, ho bonolo ho li bona ho sebelisoa lisebelisoa tsa radar tse phunyeletsang fatše, li-cable locators, kapa esita le lisebelisoa tsa tšepe.
12. Mosebetsi oa tube ea buffer ka thapo ea optical ke eng?
Li-buffer tubes li sebelisoa ka har'a likhoele tsa fiber optic ho sireletsa likhoele hore li se ke tsa kena-kenana le matšoao le maemo a tikoloho, kaha li sebelisoa hangata lits'ebetsong tsa kantle.Li-buffer tubes li boetse li thibela metsi, a bohlokoa haholo bakeng sa lisebelisoa tsa 5G hobane li sebelisoa ka ntle 'me hangata li na le pula le lehloa.Haeba metsi a kena ka har'a thapo 'me a hoama, a ka atoloha ka har'a thapo 'me a senya fiber.
13, Lithapo tsa fiber optic li kopanngoa joang?
Mefuta ea ho kopanya
Ho na le mekhoa e 'meli ea splicing, mochini kapa fusion.Litsela tsena ka bobeli li fana ka tahlehelo e tlase ea ho kenya ho feta lihokelo tsa fiber optic.
Mechanical splicing
Optical cable mechanical splicing ke mokhoa o mong o sa hlokeng fusion splicer.
Li-splices tsa mechine ke li-splices tsa optical fiber tse peli kapa ho feta tse lumellanang le ho beha likarolo tse bolokang likhoele li tsamaisana ka ho sebelisa mokelikeli o lumellanang le index.
Mechanical splicing e sebelisa splicing e nyane ea mochini e ka bang bolelele ba 6 cm le bophara ba 1 cm ho hokahanya likhoele tse peli ka ho sa feleng.Sena se tsamaisana hantle le likhoele tse peli tse se nang letho ebe li li sireletsa ka mokhoa oa mochini.
Likoahelo tse koahelang, likoahelo tsa sekhomaretsi, kapa ka bobeli li sebelisoa ho boloka splice ka ho sa feleng.
Likhoele ha lia hokahanngoa ka ho sa feleng empa li kopantsoe hammoho e le hore khanya e ka tloha ho e ’ngoe ho ea ho e ’ngoe.(tahlehelo ea ho kenya <0.5dB)
Tahlehelo ea splice hangata ke 0.3dB.Empa fiber mechanical splicing e hlahisa likhakanyo tse phahameng ho feta mekhoa ea fusion splicing.
Mochine oa optical cable mechanical splice o monyenyane, o bonolo ho o sebelisa, 'me o loketse ho lokisoa ka potlako kapa ho kenngoa ka ho sa feleng.Li na le mefuta e sa feleng le e ka kengoang hape.Li-splices tsa optical cable mechanical li fumaneha bakeng sa fiber ea mode e le 'ngoe kapa ea mefuta e mengata.
Ho kopanya ha fusion
Fusion splicing e bitsa chelete e ngata ho feta mechanical splicing empa e nka nako e telele.Mokhoa oa fusion splicing o kopanya li-cores ka ho fokotseha ho fokolang.(tahlehelo ea ho kenya <0.1dB)
Nakong ea ts'ebetso ea ho kopanya fusion, ho sebelisoa fusion splicer ho hokahanya lipheletsong tse peli tsa fiber, ebe likhalase li "kopanngoa" kapa "li kopantsoe" hammoho ho sebelisa arc ea motlakase kapa mocheso.
Sena se etsa hore ho be le kamano e hlakileng, e sa boneng, le e tsoelang pele pakeng tsa likhoele, e leng se nolofalletsang phetisetso ea optical ea tahlehelo e tlase.(Tahlehelo e tloaelehileng: 0.1 dB)
The fusion splicer e etsa optical fiber fusion ka mehato e 'meli.
1. Ho tsamaisana hantle ha likhoele tse peli
2. Etsa arc e nyane ho qhibilihisa likhoele le ho li kopanya
Ntle le tahlehelo e tlase ea splice ea 0.1dB, melemo ea splice e kenyelletsa likhakanyo tse fokolang tsa morao.
