Ho lemoha, ho fumana sebaka le ho sebetsana le lintlha tse fokolang haholo ka lik'hebole tsa optical

Kahong ea thapo ea optical, ts'ebetso ea ho fokotsa matla ke tekanyo ea bohlokoa ea tlhahlobo. Ho latela maemo a tloaelehileng a mela, sengoloa sena se sekaseka libaka le mekhoa ea ho sebetsana le lintlha tse phahameng tsa ho fokotsa matla meleng ea thapo ea optical.

I. Libaka tse Tloaelehileng tsa Libaka tse Fokolang Haholo

Kamora ho qeta ho kopanya thapo, tlhahlobo ea OTDR hangata e etsoa karolong eohle ea relay. Teko ena e netefatsa hore na litšobotsi tsa optical tsa thapo e kopantsoeng li fihlela litlhaloso tsa kaho le maemo a kamohelo. Tlhahlobo e kenyelletsa haholo-holo:

• Hore na ho fokotseha ha karolo ea relay ho tlase ho feta tlhaloso ea moralo (ke hore, hore na karolelano ea ho fokotseha ha tekanyo e fihlella litlhoko)

• Hore na tahlehelo e tloaelehileng ea manonyeletso a mahlakoreng a mabeli e fihlela litekanyetso tsa kamohelo le litlhoko tsa moralo

• Hore na leralla la mokokotlo oa backscatter le tšoana ebile le boreleli, ha ho na mehato e meholo ea ho fokotsa ntle le mehato e menyenyane e bakoang ke tahlehelo e tloaelehileng ea splice

Ha o sebedisa OTDR ho leka karolo ya relay le ho fumana dintlha tse nang le phokotso e phahameng, ho bohlokwa ho beha diparamitha tse kang sebaka, bolelele ba maqhubu, bophara ba pulse, index ya refractive, le nako ya karolelano:

• Teko ea mefuta:Beha ho latela bolelele ba karolo ea relay e le hore mothinya o nke hoo e ka bang 2/3 ea skrine ea ponts'o

• Bolelele ba maqhubu:Hangata 1310 nm le 1550 nm bakeng sa likhoele tsa kutu tse hole

• Letšoao la refractive:Sete e ipapisitse le litlhaloso tsa moetsi oa faeba

• Bophara ba ho otla ha pelo:Paramethara ea bohlokoa—e nyenyane haholo e fella ka ho se lekane ha sebaka se feto-fetohang le li-curve tse lerata; e kholo haholo e fokotsa ho nepahala ha tekanyo. E lokela ho khethoa ho latela litlhoko tsa sebaka le ho nepahala.

• Nako e tloaelehileng:Lokisa ho fihlela mohatla o kobehileng o boreleli ntle le lerata le bonahalang

Ho fumana libaka tsa liphoso ka nepo, software ea tlhahlobo ea OTDR e ka sebelisoa. Liphoso hangata li oela likarolong tse peli: liphoso tsa lebokose la splice le liphoso tsa 'mele oa cable.

II. Ho Sebetsana le Lintlha tse Fokotsang Khatello e Phahameng

Taba ea pele, fumana hore na ntlha ea ho fokotseha ho hoholo e sebakeng sa splice. Lintlheng tsa splice, likhoele tsohle hangata li bontša mehato ea ho fokotseha ea likhato tse fapaneng. Ka ho sekaseka li-curve tse ngata tsa fiber ka nako e le 'ngoe, haeba li-curve tsohle li bontša mehato sebakeng se le seng, ho ka etsahala hore ebe ke bothata ba splice.

• Lekanya 'me u bale tahlehelo ea splice ea mahlakore a mabeli ntlheng eo

• Ngola boleng bofe kapa bofe bo fetang maemo

• Bula ho koaloa ha splice 'me u etse liketso tsa ho lokisa

Haeba likhoele tse ling feela li bontša ho fokotseha ha matla sebakeng se itseng ha tse ling li sa bontše ho fokotseha ha matla, bothata e ka 'na eaba ha se karohano empa ke phoso ka har'a 'mele oa cable.

Mekhoa ea Sebaka sa Phoso

• Liphoso tse haufi-ufi:Sebelisa OTDR ho tloha setsing sa ho lekanya sebaka ho tloha sebakeng se haufi sa splice

• Liphoso tse sa feleng:Ka lebaka la ho nepahala ho fokotsehileng ha maeto a malelele, leka ho tloha ho koaloeng ha splice e haufi ho e-na le hoo.

• Kopanya data ea OTDR le lirekoto tsa kaho le tlhaiso-leseling ea ho se sebetse hantle

• Etsa litekanyo tsa tšimo ho fumana phoso ka har'a sebaka sa limithara tse ka bang 10

Mokhoa ona o fokotsa boholo ba ho epolloa, o fokotsa litšenyehelo, 'me o khutsufatsa nako ea tokiso.

Mekhoa ea ho Lokisa

1. Liphoso tsa Splice-Point

• Bula ho koaloa ha splice le ho kopanya likhoele hape

• Lekola ka nako ea sebele u sebelisa OTDR ho fihlela maemo a tahlehelo a amohelehang a fihlelleha

Haeba ho kopanya ka makhetlo a mangata ho hloleha:

• Hlahloba ho fetoha ha liphaephe tsa fiber buffer

• Netefatsa hore radius e kobeha hantle nakong ea ho kobeha ha fiber

• Hlahloba kgatello ya faeba

Haeba mathata a ntse a tsoela pele, hlahloba likarolo tsa thapo pele le ka mor'a ho kopanya. Haeba ho belaelloa hore ho na le tšenyo, khaola 'me u kopanye likhoele tsohle hape.

2. Liphoso tsa 'Mele oa Cable

Mabaka a tloaelehileng a kenyeletsa:

• Ho thinya kapa ho sotha thapo

• Tšenyo ea mechini ea kantle (mohlala, khatello e tsoang mafikeng e bakang phetoho)

• Phetoho ea tube ea buffer e lebisang ho hatelletso ea fiber

Tharollo:

• Seha karolo e senyehileng ebe o e kopanya hape

• Bakeng sa tšenyo e kholo, kenya sekwahelo sa splice 'me u lokise likhoele tse amehileng

• Haeba ho hlokahala, hlobola sekotjana sa kantle 'me u lokise kapa u nke li-buffer tube tse senyehileng sebaka.

Mehato ea Thibelo

• Hlahloba bolelele ba thapo e setseng pele o e kopanya

• Khaola bolelele bo eketsehileng ho tloha lipheletsong tsa thapo tse belaetsang ho qoba tšenyo e patehileng

• Tlohela bofokoli bo lekaneng libakeng tse tsejoang bakeng sa litokiso tse bonolo nakong e tlang

Litlhoko tsa Teko

Basebetsi ba liteko ba lokela ho sebelisana le litsebi tsa masimong le ho etsa liteko tsa OTDR mehatong e latelang:

1. Kamora hore ho kopanya ho phetheloe

2. Kamora hore ho kobeha ha fiber ho qetiloe

3. Kamora ho koaloa ha splice

Ke feela kamora ho netefatsa hore mathata a ho fokotsa ts'ebetso a rarollotsoeng moo sehlopha se ka tlohang sebakeng seo.
