FTTx yog dab tsi?

Raws li peb pom qhov yuav tsum tau muaj kev nce qib ntawm cov bandwidth uas xa mus rau cov neeg siv khoom, vim yog 4K siab txhais TV, cov kev pabcuam xws li YouTube thiab lwm yam kev pabcuam sib koom ua yeeb yaj kiab, thiab cov kev pabcuam sib koom ua phooj ywg, peb tau pom qhov nce hauv FTTx kev teeb tsa lossis ntau dua Fiber Rau "x".Peb txhua tus nyiam xob laim nrawm hauv internet thiab cov duab pom tseeb ntawm peb 70 nti TV's thiab Fiber To The Home - FTTH yog lub luag haujlwm rau cov khoom siv me me no.

Yog li "x" yog dab tsi?"x" tuaj yeem sawv ntsug rau ntau qhov chaw uas cable TV lossis broadband cov kev pabcuam xa mus rau, xws li Lub Tsev, Ntau Lub Tsev Nyob Hauv Tsev, lossis Chaw Ua Haujlwm.Cov hom kev xa tawm no uas xa cov kev pabcuam ncaj qha rau cov neeg siv khoom thaj chaw thiab qhov no tso cai rau kev sib txuas nrawm dua thiab muaj kev ntseeg siab dua rau cov neeg siv khoom.Qhov chaw sib txawv ntawm koj qhov kev xa tawm tuaj yeem ua rau muaj kev hloov pauv ntau yam uas yuav cuam tshuam rau cov khoom koj xav tau rau koj qhov project.Cov xwm txheej uas tuaj yeem cuam tshuam rau Fiber Rau Qhov "x" kev xa tawm tuaj yeem yog ib puag ncig, huab cua cuam tshuam, lossis twb muaj cov txheej txheem uas twb muaj lawm uas yuav tsum tau coj mus rau hauv tus account thaum tsim lub network.Hauv ntu hauv qab no, peb yuav mus hla qee yam khoom siv uas siv ntau tshaj plaws hauv Fiber Rau Qhov "x" xa mus.Yuav muaj kev hloov pauv, sib txawv, thiab cov chaw tsim khoom sib txawv, tab sis rau feem ntau, txhua yam khoom siv zoo nkauj hauv kev xa tawm.

Chaw Ua Haujlwm Chaw Taws Teeb Nruab Nrab

Ib tug ncej los yog ncoo mounted nyob rau hauv central chaw ua hauj lwm los yog network interconnection enclosure ua hauj lwm raws li ib tug tej thaj chaw deb qhov chaw thib ob rau cov neeg muab kev pab cuam uas nyob rau ntawm ib tug ncej los yog hauv av.Lub kaw lus no yog lub cuab yeej uas txuas cov neeg muab kev pabcuam rau tag nrho lwm cov khoom hauv FTTx xa mus;lawv muaj qhov Optical Line Terminal, uas yog qhov kawg rau cov neeg muab kev pabcuam thiab qhov chaw uas hloov pauv ntawm cov teeb liab hluav taws xob mus rau fiber ntau cov teeb liab tshwm sim.Lawv tau nruab nrog cov cua txias, cua sov chav, thiab lub zog hluav taws xob kom lawv tuaj yeem tiv thaiv cov khoom.Lub chaw ua haujlwm hauv nruab nrab no pub cov hub enclosures ntawm sab nraum cov nroj tsuag fiber ntau optic cables, xws li aerial lossis underground faus cables nyob ntawm qhov chaw ntawm lub hauv paus chaw ua haujlwm.Qhov no yog ib qho tseem ceeb tshaj plaws nyob rau hauv ib qho FTTx kev teeb tsa, vim qhov no yog qhov uas txhua tus pib.

Fiber Distribution Hub

Cov ntaub ntawv no yog tsim los ua qhov sib txuas lossis qhov chaw sib tham rau fiber ntau optic cables.Cables nkag mus rau hauv lub thawv los ntawm OLT - Optical Line Terminal thiab tom qab ntawd cov teeb liab no tau muab faib los ntawm cov fiber ntau optical splitters lossis splitter modules thiab xa rov qab los ntawm cov xaim xaim xaim xa mus rau cov tsev lossis ntau lub tsev xauj tsev.Chav tsev no tso cai rau kev nkag mus rau cov cables ceev ceev kom lawv tuaj yeem muab kev pabcuam lossis kho yog tias xav tau.Koj tseem tuaj yeem sim hauv chav tsev no kom ntseeg tau tias txhua qhov kev sib txuas ua haujlwm tau zoo.Lawv tuaj ntawm ntau qhov ntau thiab tsawg thiab cov duab nyob ntawm qhov kev teeb tsa uas koj tab tom ua thiab tus naj npawb ntawm cov neeg siv khoom uas koj tab tom npaj rau kev pabcuam los ntawm ib chav tsev.

Splice Enclosures

Sab nraum zoov splice enclosures yog muab tso rau tom qab lub fiber faib hub.Cov splice sab nraum zoov no tso cai rau cov tsis siv sab nraum zoov cable kom muaj qhov chaw passive uas cov fibers tuaj yeem nkag tau los ntawm midspan thiab tom qab ntawd koom nrog rau qhov poob cable.

Splitters

Splitters yog ib qho tseem ceeb tshaj plaws players hauv ib qhov project FTTx.Lawv tau siv los faib cov teeb liab tuaj kom ntau cov neeg siv khoom tuaj yeem muab kev pabcuam nrog ib qho fiber ntau.Lawv tuaj yeem muab tso rau hauv qhov chaw faib khoom fiber ntau, lossis hauv cov khoom sib txuas sab nraum zoov.Splitters feem ntau yog txuas nrog SC / APC connectors rau kev ua haujlwm zoo.Cov splitters tuaj yeem muaj kev sib cais xws li 1 × 4, 1 × 8, 1 × 16, 1 × 32, thiab 1 × 64, vim FTTx kev xa tawm tau dhau los ua ntau dua thiab ntau lub tuam txhab xov tooj tau txais cov thev naus laus zis.Cov kev sib cais loj dua tau ua ntau dua xws li 1 × 32 lossis 1 × 64.Cov kev sib cais no tiag tiag cim cov naj npawb ntawm cov tsev uas tuaj yeem ncav cuag los ntawm ib qho fiber ntau no uas khiav mus rau qhov muag pom.

Network Interface Devices (NIDs)

Network Interface Devices lossis NID lub thawv feem ntau nyob sab nraum ib lub tsev;lawv feem ntau tsis siv hauv MDU kev xa tawm.NID's yog cov thawv ntim ib puag ncig uas tau muab tso rau ntawm ib sab ntawm lub tsev kom tso cai rau cov kab hluav taws xob nkag mus.Cov kab no feem ntau yog ib qho kev ntsuas sab nraum zoov uas tau txiav nrog SC / APC txuas.NID's ib txwm tuaj nrog qhov hluav taws xob grommets uas tso cai rau kev siv ntau qhov ntau thiab tsawg.Muaj qhov chaw nyob rau hauv lub thawv rau adapter panels thiab splice tes tsho.NID's yog pheej yig heev, thiab feem ntau me me me piv nrog MDU lub thawv.

Multi Tenant Distribution Box

Lub thawv ntim ntau lub thawv lossis MDU lub thawv yog cov phab ntsa mountable uas tau tsim los tiv thaiv cov xwm txheej hnyav thiab tso cai rau ntau cov khoom siv fiber ntau tuaj, feem ntau yog nyob rau hauv daim ntawv ntawm sab hauv / sab nraum zoov faib cable, lawv tuaj yeem ua tsev kho qhov muag splitters uas raug txiav nrog SC / APC connectors thiab splice tes tsho.Cov thawv no nyob rau hauv txhua lub tsev ntawm lub tsev thiab lawv tau muab faib ua ib qho fibers los yog xaim cables uas khiav mus rau txhua chav nyob hauv pem teb.

Demarcation Box

Lub thawv demarcation feem ntau muaj ob qhov chaw nres nkoj fiber ntau uas tso cai rau cable.Lawv muaj built-in splice tes tsho tuav.Cov thawv no yuav raug siv nyob rau hauv ib chav tsev ntau tus neeg xauj tsev, txhua chav tsev lossis chaw ua haujlwm chaw ua haujlwm uas lub tsev muaj yuav muaj ib lub thawv demarcation uas txuas nrog cable rau MDU Box nyob rau hauv pem teb ntawm chav tsev ntawd.Cov no feem ntau yog pheej yig thiab me me daim ntawv kom lawv tuaj yeem muab tso rau hauv ib chav tsev yooj yim.

Thaum kawg ntawm hnub, FTTx kev xa tawm tsis mus qhov twg, thiab cov no tsuas yog qee yam ntawm cov khoom uas peb tuaj yeem pom hauv kev xa tawm FTTx.Muaj ntau txoj hauv kev uas tuaj yeem siv tau.Nyob rau yav tom ntej, peb tsuas yog pom ntau thiab ntau dua ntawm cov kev xa tawm no uas peb pom ntxiv nce ntxiv hauv kev thov rau bandwidth raws li kev siv thev naus laus zis.Vam tias, kev xa tawm FTTx yuav los rau hauv koj cheeb tsam kom koj tuaj yeem txaus siab rau cov txiaj ntsig ntawm kev muaj kev sib txuas lus nrawm dua thiab muaj kev ntseeg siab dua rau koj cov kev pabcuam.
