Fiber rau hauv lub tsev (FTH) yog lub kaw lus uas nruab fiber ntau optics los ntawm lub hauv paus taw tes ncaj qha rau hauv cov tsev ib txwm muaj xws li tsev. FTH xa tau tau tuaj ntev ua ntej cov neeg siv cov fiber ntau optics es tsis txhob tooj liab rau broadband siv internet.
Muaj ob txoj hauv kev los rau kev siv FTH network:nquag kho qhov muag(Aon) thiab passiveKho qhov muag(Pon).
Yog li Aon thiab Pon Networks: Dab tsi yog qhov sib txawv?
Dab tsi yog Aon Network?
Ib tug Aon yog tus taw tes-rau-taw tes lub network hauv uas txhua tus neeg sau npe tau nws tus kheej cov kab fiber ntau uas tau txiav tawm ntawm ib qho kho qhov muag. Ib tug Aon Network encompasses electrically powered hloov cov khoom siv xws li routers lossis hloov cov pej xeem los tswj teeb liab kev faib tawm thiab kev taw qhia kev taw qhia rau cov neeg siv khoom tshwj xeeb.
Cov pob hluav taws xob tau muab tua thiab tawm ntawm ntau txoj hauv kev los ncaj qha cov cim tuaj thiab cov cim kev cia siab ntawm Ethernet Technology ua rau kev cuam tshuam ntawm cov neeg muab kev pab cuam yooj yim. Cov Qhua Tuaj tuaj yeem xaiv cov khoom kho vajtse uas muab cov ntaub ntawv tsim nyog thiab ntsuas tau raws li lawv cov kev xav tau nce ntxiv yam tsis tau rov qab ua haujlwm hauv lub network. Txawm li cas los xij, Aon Networks yuav tsum muaj tsawg kawg yog ib txoj kev hloov ua ke ib tus neeg ua haujlwm.
Tus Pon Network yog dab tsi?
Tsis zoo li Aon tes hauj lwm, Pon yog tus taw tes archerve architecture uas siv passive splitters cais thiab sau cov cim kho qhov muag. Fiber ntau txhais lus pub cov Pon Network los pab cov neeg ua haujlwm ntau rau ib qho fiber ntau yam tsis tas yuav tsum tau siv cov neeg siv cais ntawm lub hub thiab cov neeg siv kawg.
Raws li lub npe qhia, Pon Networks tsis suav nrog lub tshuab hloov hluav taws xob hloov thiab sib qhia Fiber Bundles rau ib feem ntawm lub network. Cov cuab yeej nquag tsuas yog xav tau ntawm qhov chaw thiab tau txais xaus ntawm lub teeb liab.
Nyob rau hauv ib tug raug pon network, lub plc splitter yog qhov chaw nruab nrab. Cov khoom siv Fiber ntau OPTIC sib txuas ntau qhov kev ntsuas kho qhov muag rau hauv ib qho kev tawm tshiab, lossis muab nws cov khoom tawm ntawm cov neeg tawm. Cov kais dej no rau Pon yog Bidirectional. Txhawm rau kom pom tseeb, cov phiajcim fiber ntau tuaj yeem raug xa cov dej ntws hauv nruab nrab ntawm lub chaw haujlwm hauv nruab nrab kom tshaj tawm rau txhua tus neeg xa khoom. Cov cim los ntawm cov neeg rau npe tuaj yeem xa cov nce toj thiab sib xyaw ua ke rau hauv ib qho fiber ntau los txuas lus nrog lub chaw haujlwm.
Aon vs Pon tes hauj lwm: Qhov sib txawv thiab cov kev xaiv
Ob lub Pon thiab Aon Networks ua cov fiber ntau lub ntsej muag ntawm cov txheej txheem ftth, tso cai rau tib neeg thiab cov lag luam nkag mus rau hauv Is Taws Nem. Ua ntej xaiv ib lub pon lossis Aon, nws yog ib qho tseem ceeb kom nkag siab txog qhov sib txawv ntawm lawv.
Kos Npe Distrimal
Thaum nws los txog rau Aon thiab Pon Networks, qhov sib txawv tseem ceeb ntawm lawv yog txoj kev kho kho qhov muag tau muab faib rau txhua tus neeg siv khoom hauv FTTH system. Hauv Aon system, subscribers tau mob siab rau cov pob roj sib xyaw, uas tso cai rau lawv kom lawv nkag tau tib bandwidth, es tsis yog sib koom ib qho. Nyob rau hauv lub pon network, subscribers faib ib feem ntawm network lub fiber pob hauv lub pon. Yog li ntawd, cov neeg siv Pon kuj tseem tuaj yeem pom tau tias lawv lub kaw lus qeeb qeeb vim tias txhua tus neeg siv sib qhia tib bandwidth. Yog tias muaj teeb meem tshwm sim hauv lub pon system, nws yuav yog qhov nyuaj nrhiav cov khoom ntawm qhov teeb meem.
Nqi
Cov nuj nqis loj tshaj plaws hauv lub network yog tus nqi ntawm cov khoom siv fais fab thiab saib xyuas. Pon siv cov khoom siv passive uas yuav tsum tau muaj kev txij nkawm tsawg dua thiab tsis muaj fais fab dua li ib lub network network, uas yog tus nquag network. Yog li Pon yog pheej yig dua Aon.
Kev Them Nqi Nqi thiab Kev Siv
Aon tuaj yeem npog ib qho deb ntawm li 90 mais, hos lub Pon feem ntau yog txwv los ntawm cov kab muaj kuab lom roj fiber ntau txog 20 mais ntev. Qhov no txhais tau tias Pon cov neeg siv yuav tsum yog thaj chaw ze rau lub teeb liab pib.
Ib qho ntxiv, yog tias nws cuam tshuam nrog ib daim ntawv thov lossis kev pabcuam tshwj xeeb, tus naj npawb ntawm lwm yam yuav tsum tau txiav txim siab. Piv txwv li, yog tias RF thiab cov kev pabcuam video yuav tsum tau tso tawm, ces Pon feem ntau yog cov kev daws teeb meem nkaus xwb. Txawm li cas los xij, yog tias txhua qhov kev pabcuam yog Internet prococol raws li, tom qab ntawd Pon lossis Aon yuav tsim nyog. Yog tias qhov kev ncua ntev tau koom tes thiab muab lub zog thiab txias rau cov khoom siv hauv thaj teb tuaj yeem muaj teeb meem, tom qab ntawd Pon yuav yog qhov kev xaiv zoo tshaj plaws. Los yog, yog tias lub hom phiaj cov neeg siv khoom lag luam yog kev lag luam lossis txoj haujlwm cuam tshuam nrog ntau cov tsev nyob, tom qab ntawd Aon network yuav tsim nyog.
Aon vs. Pon Network: uas ftth koj xum?
Thaum xaiv tau ntawm Pon lossis Aon, nws yog ib qho tseem ceeb uas yuav tau tshaj tawm cov kev pabcuam uas tau xa tawm ntawm lub network, thiab cov neeg yuav khoom hauv thawj cov neeg yuav khoom li cas. Coob tus neeg ua haujlwm tau tso cai sib xyaw ntawm ob qho haujlwm sib txawv hauv cov xwm txheej sib txawv. Txawm li cas los xij, raws li qhov xav tau ntawm kev sib cuam tshuam nrog kev sib cuam tshuam thiab kev tsim kho network tseem pheej tuaj yeem siv cov ntawv thov Pon lossis Aon cov ntawv thov kom tau raws li kev xav tau ntawm yav tom ntej.
