3. Ua tib zoo saib xyuas cov kev pheej hmoo ntawm FTTH thev naus laus zis thiab zam qhov muag tsis pom kev thov kev txhawb nqa kom tau txais kev pabcuam puv ntoob

Coob tus neeg siv xav tau FTTH los txhawb txhua qhov kev pabcuam, thiab ib txhij txhawb nqa kev siv Is Taws Nem siv dav dav, txuas xov tooj cua (CATV) nkag mus thiab siv xov tooj siv tas mus li, uas yog, nkag mus ua si peb zaug, vam tias yuav ua tiav FTTH siv thev naus laus zis hauv ib kauj ruam. Peb ntseeg tias nws yog qhov zoo tshaj los tuaj yeem txhawb nqa kev siv Internet tau dav, txwv TV (CATV) nkag mus thiab nkag tau xov tooj zoo ib yam, tab sis qhov tseeb muaj cov txuj ci loj heev.

Tam sim no, ntawm 5 lab tus neeg siv FTTH hauv ntiaj teb, ntau dua 97% ntawm FTTH nkag mus siv tes hauj lwm tsuas yog siv kev siv xov tooj cua nkag mus rau Is Taws Nem, vim tias tus nqi ntawm FTTH los muab xov tooj ib txwm muaj ntau dua li tus nqi ntawm kev siv xov tooj tam sim no, thiab siv cov khoom siv kho qhov muag kom xa tau ib txwm tsau Lub xov tooj kuj muaj teeb meem ntawm xov tooj fais fab mov. Txawm hais tias AON, EPON thiab GPON txhua tus txhawb nqa kev ua si peb zaug. Txawm li cas los xij, EPON thiab GPON cov qauv nyuam qhuav tau tshaj tawm, thiab nws yuav siv sijhawm rau cov thev naus laus zis kom paub tab. Kev sib tw ntawm EPON thiab GPON thiab kev txhawb nqa yav tom ntej ntawm ob tus qauv no tseem tsis tau paub meej, thiab nws cov ntsiab lus-rau-sib npaug passive network qauv tsis haum rau Tuam Tshoj txoj kev ntom ntom. Daim ntawv thov thaj chaw nyob. Ib qho ntxiv, EPON thiab GPON cov cuab yeej cuam tshuam yuav tsum muaj tsawg kawg 5 xyoos ntawm kev ua qauv thiab ua kom tiav. Hauv 5 xyoos tom ntej, nws yuav nyuaj rau kev sib tw nrog Ethernet P2P cov cuab yeej tam sim no hais txog tus nqi thiab kev muaj koob npe. Tam sim no, opto cov cuab yeej siv hluav taws xob nyob deb ntawm qhov muaj peev xwm ua tau raws li qhov yuav tsum tau ua tsawg. Tus nqi PON qhov xav tau. Nws tuaj yeem pom tias qhov muag tsis pom kev ntawm FTTH kev pabcuam puv ntoob siv EPON lossis GPON nyob rau theem no yuav ua rau muaj kev phom sij loj.

Ntawm kev nkag mus rau lub network, nws yog qhov hloov pauv tsis tau rau kev siv fiber ntau los hloov ntau yam tooj liab tooj liab. Txawm li cas los xij, kho qhov muag fiber yuav hloov pauv cov tooj liab txhua hmo. Nws yog qhov tsis muaj tseeb thiab tsis xav txog rau txhua qhov kev pabcuam kom nkag mus tau los ntawm cov xov paj fiber. Ib qho kev txhim kho thev naus laus zis thiab daim ntawv thov yog maj mam, thiab FTTH tsis muaj qhov tshwj xeeb. Yog li ntawd, hauv kev txhim kho thawj zaug thiab txhawb nqa FTTH, kev sib koom ua ke ntawm cov kho qhov muag fiber ntau thiab tooj liab tooj liab yog qhov tsis yooj yim sua. Kev nyob ua ke ntawm cov kho qhov muag fiber ntau thiab tooj liab tooj liab tuaj yeem ua rau cov neeg siv thiab cov neeg siv xov tooj sib txuas kom tsis txhob muaj kev phom sij ntawm FTTH. Ua ntej tshaj plaws, AON kev siv thev naus laus zis tuaj yeem siv tau thaum ntxov kom ua tiav FTTH kev siv dav dav ntawm tus nqi qis, thaum CATV thiab cov xov tooj ib txwm tseem siv xov tooj sib txuas thiab sib txuas. Rau cov tsev nyob, CATV nkag mus kuj tseem tuaj yeem ua tiav ib txhij los ntawm kev siv fiber ntau ntawm tus nqi qis. Qhov thib ob, muaj cov teeb meem kev lag luam hauv kev muab cov kev pabcuam xov tooj hauv Suav teb. Cov neeg ua haujlwm sib tham hauv xov tooj tsis raug tso cai ua haujlwm CATV. Ntawm qhov tsis sib xws, cov tswv lag luam CATV tsis raug tso cai ua haujlwm cov kev sib tham hauv xov tooj (xws li xov tooj), thiab qhov xwm txheej no yuav siv sijhawm ntev heev yav tom ntej. Lub sijhawm tsis tuaj yeem hloov pauv, yog li tus neeg teb xov tooj tsis tuaj yeem muab kev pabcuam ua si peb zaug ntawm FTTH nkag mus rau lub network; dua, txij li lub neej ntawm cov hlua kho qhov muag tuaj yeem mus txog 40 xyoo, thaum tooj liab tooj liab feem ntau yog 10 xyoo, thaum tooj liab tooj liab yog vim lub neej Thaum kev sib txuas lus tsis zoo, tsis tas yuav tsum tso ib txoj hlua. Koj tsuas yog yuav tsum tau hloov kho cov cuab yeej siv fiber ntau los muab cov kev pabcuam muab los ntawm cov tooj liab tooj liab qub. Qhov tseeb, tsuav yog cov thev naus laus zis paub tab thiab tus nqi siv tau, koj tuaj yeem hloov kho txhua lub sijhawm. Cov cuab yeej siv hluav taws xob kho qhov muag, sijhawm txaus siab rau qhov yooj yim thiab kev siv bandwidth siab los ntawm FTTH thev naus laus zis tshiab.

Txhawm rau suav nrog, qhov kev xaiv tam sim no ntawm cov kho qhov muag fiber ntau thiab tooj liab txuas ua ke, siv AON's FiberP2P FTTH kom ua tiav kev siv xov tooj cua dav dav, CATV thiab cov xov tooj ib txwm siv tseem siv coaxial thiab sib tw ua ke, uas tuaj yeem zam kev pheej hmoo ntawm FTTH thev naus laus zis tib yam sijhawm, txaus siab rau qhov yooj yim thiab kev siv bandwidth siab coj los ntawm FTTH kev siv thev naus laus zis tshiab sai li sai tau.
