Dab tsi yog FTTX raws nraim?

Raws li peb pom qhov kev xav tau rau qhov nce siab nce siab nyob rau hauv tus nqi ntawm bandwidth uas tau xa mus rau cov neeg siv khoom, thiab lwm yam kev sib koom ua yeeb yaj kiab, peb tau pom qhov nce hauv FTTX lossis ntau dua rau "x". Peb txhua tus nyiam xob laim sai thiab cov npliag duab ntshiab ntawm peb 70 nti TV's thiab fiber yog lub luag haujlwm rau cov khoom kim me ntsis.

Yog li dab tsi yog "X"? "X" tuaj yeem sawv ntsug rau ntau qhov chaw uas cable TV lossis cov kev pabcuam dav dav tau xa mus rau, xws li tsev, ntau lub tsev haujlwm. Cov khoom siv uas xa tawm ncaj qha rau cov kev pabcuam uas xa mus ncaj qha rau cov qhua tuaj noj mov thiab qhov no tso cai rau kev sib txuas nrawm nrawm thiab muaj kev ntseeg siab rau cov neeg siv khoom. Txawv qhov chaw sib txawv ntawm koj kev xa tawm tuaj yeem ua rau muaj ntau yam kev hloov pauv ntawm ntau yam uas koj xav tau rau koj qhov project. Yam uas tuaj yeem cuam tshuam rau cov fiber ntau rau "X" kev xa tawm tuaj yeem yog ib puag ncig, huab cua muaj feem uas yuav tsum tau coj mus rau hauv tus account. Hauv cov seem hauv qab no, peb yuav mus hla qee cov khoom siv uas siv nyob rau hauv ib fiber ntau nyob rau hauv ib tug fiber ntau rau "x" kev xa tawm. Yuav muaj cov hloov pauv, cov qauv sib txawv, thiab cov khoom sib txawv, tab sis rau feem ntau, tag nrho cov khoom siv yog cov qauv zoo nkauj hauv kev xa tawm.

Tej thaj chaw deb chaw ua haujlwm

Ib tug ncej lossis ncoo mounted hauv nruab nrab chaw ua haujlwm lossis network sib tshuam ua haujlwm raws li thaj chaw deb chaw rau cov chaw muab kev pabcuam uas nyob ntawm tus ncej lossis hauv av. Cov ntaub thaiv no yog cov cuab yeej uas txuas cov muab kev pabcuam rau txhua tus hauv FTTX xa tawm; Lawv muaj cov kab kho qhov muag lub davhlau ya nyob twg, uas yog qhov kawg rau cov muab kev pabcuam thiab qhov chaw hloov pauv ntawm cov cim hluav taws xob rau cov cim hluav taws xob tau tshwm sim. Lawv tau nruab nrog cua txias, cov cua sov nyob, thiab lub zog hluav taws xob kom lawv tuaj yeem tiv thaiv los ntawm cov ntsiab lus. Lub chaw ua haujlwm nruab nrab no pub rau lub hub tso rau sab nraud uas siv sab nraud, txawm yog kev faus neeg faus neeg nyob ntawm thaj chaw ntawm lub chaw haujlwm. Qhov no yog ib qho tseem ceeb tshaj plaws hauv FTTX phuv phuv tas, vim qhov no yog txhua tus pib.

Fiber ntau ittion Hubdistrib

Cov kab ke no yog tsim los ua qhov kev sib txuas lossis lub rooj sib tham rau cov fiber ntau cov cable. Cables nkag mus rau hauv qhov thaiv ntawm OLT - kab teeb tsa opt opt ​​spl spl thiab ces cov teeb liab no sib cais los ntawm kev poob qis dua uas yog tom qab ntawd xa mus rau cov tsev lossis cov tsev ntiav neeg xauj tsev ntau dua. Chav tsev no tso cai rau kev nkag mus ceev rau cov cables kom lawv tuaj yeem ua haujlwm yog tias xav tau. Koj tseem tuaj yeem sim nyob rau hauv chav no kom ntseeg tau tias txhua qhov kev sib txuas tau nyob hauv kev ua haujlwm. Lawv tuaj nyob rau ntau qhov ntau thiab tsawg nyob ntawm cov kev teeb tsa uas koj tau ua thiab cov neeg yuav khoom uas koj npaj siab ua haujlwm ntawm ib chav tsev.

Splice Cov Khaub Ncaws

Cov kab mob sab nraum zoov Splice tau muab tso rau tom qab cov fiber ntau faib hub. Cov kab mob sab nraum zoov tso cai rau cov neeg tsis siv cov fibers uas cov fibers tuaj yeem nkag ntawm midsan thiab tom qab ntawd koom nrog txoj kev nco.

Rab phom

Splitters yog ib qho ntawm cov players tseem ceeb hauv txhua qhov phiaj xwm FTTX. Lawv tau siv los faib cov teeb liab tuaj cuag kom ntau cov neeg siv khoom muaj peev xwm ua haujlwm nrog ib fiber. Lawv tuaj yeem muab tso rau hauv Fiber Fiber Fiberuting Hubs, lossis nyob rau sab nraum zoov splice tso cai. Splitters feem ntau txuas nrog SC / APC txuas rau kev ua tau zoo tshaj plaws. Cov splitters tuaj yeem muaj kev sib cais xws li 1 × 4, 1 × 8, 1 × 16, 1 × 16, 1 × 6, xws li FTTX Cov tuam txhab ua si tau ntau dua thiab muaj xov tooj cua ntau ntxiv. Cov kauj tsheb loj yog ua ntau xws li 1 × 32 lossis 1 × 64. Cov kab sib faib no tiag piv txog cov tsev uas tau mus txog ntawm no ib fiber ntau uas tab tom khiav mus rau lub khoos phis tawm kho qhov muag.

Network interface pab kiag li lawm (Nids)

Network interface cov cuab yeej lossis cov nid thawv feem ntau nrhiav sab nraud ntawm ib lub tsev; Lawv tsis yog feem ntau yog siv hauv MDU xa cov khoom. Nid's yog ib puag ncig lub thawv uas tau muab tso rau ntawm ib sab ntawm lub tsev kom tso cai rau lub qhov muag cable nkag mus. Cov cab no feem ntau yog sab nraum zoov-rated poob cable npaj nrog SC / APC Connector. Nid ib txwm tuaj nrog hluav taws ua ke uas tso cai rau kev siv ntawm ntau qhov ntau thiab tsawg. Muaj chaw seem nyob rau hauv lub thawv rau adapter panels thiab txi tsho. Nid's yog pheej yig pheej yig, thiab feem ntau me me hauv qhov loj me nrog MDU lub thawv.

Cov neeg ntaus nqi ntau lub thawv

Ntau lub thawv xaub los yog MDU faib khoom siv cable, feem ntau lawv tuaj yeem tso tawm hauv cov kab ke hauv sab hauv tsev, feem ntau yog cov khoom siv sab hauv tsev, feem ntau yog cov khoom siv sab hauv tsev, feem ntau yog cov khoom siv sab hauv tsev, feem ntau yog cov khoom siv sab nraud. Cov npov no nyob rau hauv txhua lub tsev ntawm lub tsev thiab lawv tau faib tawm mus rau hauv ib leeg fibers lossis poob cov cable lossis poob rau txhua chav nyob rau hauv chav ntawd.

Lub thawv demarcation

Lub thawv demarcation feem ntau muaj ob lub fiber chaw ports uas tso cai rau cable. Lawv tau ua cov roj sib txig sib txig sib luag. Cov npov no yuav siv nyob rau hauv ntau qhov chaw xauj tsev, ib koog tsev kawm ntawv uas lub tsev muaj kev sib txuas nrog rau ntawm lub thawv mdu nyob rau hauv pem teb ntawd. Cov no feem ntau pheej pheej pheej pheej yig thiab daim foos me me kom lawv thiaj li tso tau yooj yim hauv ib chav.

Thaum kawg ntawm lub hnub, FTTX cov khoom xa tawm tsis mus qhov twg, thiab cov no tsuas yog qee cov khoom uas peb tuaj yeem pom hauv ib txwm xa cov ntawv FTX xa tawm. Muaj ntau txoj kev xaiv tawm muaj uas tuaj yeem siv tau. Nyob rau yav tom ntej ze, peb tsuas pom tau ntau dua thiab ntau dua ntawm cov kev xa tawm no nyob rau hauv uas peb pom ntxiv nce ntxiv hauv kev thov rau bandwidth li thev naus laus zis. Vam tias, kev xa tawm FTTX yuav los rau koj thaj chaw kom koj tuaj yeem txaus siab rau cov txiaj ntsig ntawm kev ntseeg tau rau koj cov kev pabcuam.
