Vim tias kev sib txuas lus fiber ntau muaj qhov zoo ntawm kev muaj peev xwm loj, kev nyob deb thiab kev cuam tshuam los tiv thaiv hluav taws xob, kev sib txuas lus fiber ntau tau zoo rau cov kev xav tau ntawm niaj hnub no' s lub zog sib txuas lus. Hauv tshwj xeeb, cov kab ke kho qhov muag fiber ntau ua haujlwm nyiaj siv ua haujlwm hauv av hlau (OPGW) ua ke cov cuab yeej muaj zog, hluav taws xob muaj zog thiab zoo corrosion tsis kam ntawm aluminium clad steel hlau, zoo ua ke cov fais fab nyiaj siv ua haujlwm hauv av hlau nrog kev sib txuas lus optical fiber, thiab yog li cuam tshuam. los ntawm cov zog hluav taws xob. Kev lag luam koom nrog qhov tseem ceeb thiab tau maj mam nce qib.
Muaj ntau ntau yam ntawm cov ua tau zoo kom muaj fiber ntau-rau-tsev. Muaj ob hom tseem ceeb: ib qho yog qhov taw tes-rau-daim ntawv topology, ib lub fiber yog siv los ntawm lub hauv paus chaw haujlwm rau txhua tus neeg siv; lwm qhov yog qhov ntsuas nrawm dhau los siv cov taw tes-rau-ntau sib xws. Network (PON), kev daws teeb meem-rau ntau qhov kev sib txuam uas tuaj yeem txo tsawg ntawm cov khoos phis tawm thiab cov khoom siv fiber ntau, thiab txo qhov chaw sib tw xav tau los ntawm lub chaw haujlwm nruab nrab, muaj cov nqi tsim nyog thiab tau dhau los ua lub hauv paus.
Muaj ob hom khoom siv los siv rau kev nkag tau hluav taws xob. Ib qho yog cov khoom siv hauv chaw ua haujlwm tau muab tso rau hauv kev sib txuas xov tooj xov tooj' s chav tsev computer, hu ua cov kab hluav taws xob (OLT), thiab lwm qhov yog cov khoom siv ze rau cov neeg siv kawg, hu ua optical network unit (ONU). Los ntawm cov xwm txheej kev txhim kho tam sim no, cov tsev neeg fiber ntau kuj koom nrog ntau yam kev lag luam thiab pawg, xws li cov ntoo fiber sab hauv tsev, kev tsim vaj tsev thiab kev siv, uas yog cov tswv yim rau tag nrho cov kev lag luam telecom thiab txawm tias cov ntaub ntawv kev lag luam.
Tam sim no, nyob rau hauv kev saib cov xov tooj hluav taws xob, cov hotspots hauv kev lag luam yog ob qho kev daws teeb meem rau passive optical network: GPON thiab EPON. Yooj yim muab, qhov qub tau muaj zog txhawb nqa kev lag luam muaj peev xwm thiab qhov xa tau ntau dua, uas tsim nyog rau kev xa tawm ntawm cov neeg lag luam siab thiab cov neeg nyob hauv lub sijhawm ntawm kev ua haujlwm puv ntoob, tab sis tus nqi kuj siab dua. EPON yog feem ntau rau cov ntaub ntawv xa mus, thiab cov tub ntxhais muaj txiaj ntsig yog tias tus nqi kuj tsawg. Tam sim no, ob qho tib si thev naus laus zis muaj nyob rau ntau qhov chaw thov, thiab txhua tus nyias muaj nyias qhov zoo. Nws yog tsim nyog sau cia tias EPON thiab GPON tau hloov mus rau hauv lub caij nyoog ntawm 10G. Hauv lub sijhawm luv luv, 10G EPON muaj qhov zoo dua 10G GPON, uas feem ntau yog qhov teebmeem nqi. Thiab ntau tus neeg ua haujlwm ntseeg tias bandwidth yuav txaus nyob rau ob peb xyoos tom ntej. Yog li no, lub caij nyoog ntawm kev sib xyaw ob PONs yuav tsum muaj nyob rau qee lub sijhawm. Qhov tseeb, nyob rau hauv tus txheej txheem ntawm kev tsim kho network thiab network, kev tsim kho hom qauv ntawm GPON thiab EPON tsis txawv ntau, tsuas yog txawv cov kev xaiv thev naus laus zis ntawm cov neeg siv khoom siv. Tam sim no, cov kev pabcuam kev pabcuam muaj peev xwm ntawm GPON yog qhov pib ib yam nkaus li EPON, thiab tsis muaj kev pabcuam uas GPON tuaj yeem ua tau tab sis EPON tuaj yeem' t ua. Nyob rau hauv lub neej yav tom ntej, hauv 10G era, ob lub thev naus laus zis yog qhov yuav sib koom ua ke, uas yog, tib lub platform kev txhawb nqa ob 10G EPON thiab 10G GPON. Cov khoom lag luam uas twb muaj lawm tau pib laij tawm qhov sib txawv ntawm ob qho thev naus laus zis.
Nyob rau hauv dav dav, nyob rau hauv lub tsis muaj lwm yam epoch-txiav txim siab technology, fiber-optic tsev neeg kev nkag tau yog lub hom phiaj qhov kawg ntawm broadband nkag tau nyob rau hauv ob peb xyoos tom ntej los yog txawm xyoo lawm, thiab nws yuav tsav txoj kev loj hlob ntawm ib tug series ntawm kev lag luam. Kev lag luam loj ntawm ntau pua ntawm billions thiab txawm trillions ntawm yuan. Yog li no, fiber-rau-lub-tsev yog ib qho tseem ceeb rau kev lag luam kev sib txuas lus kom tau txais kev tsim kho kom ruaj khov, thiab nws tseem yog ib qho cuab yeej tseem ceeb rau kev lag luam hauv xov tooj los txhawb cov ntaub ntawv sib raug zoo.
Fiber-rau-lub-tsev yog ib feem ntawm qhov kev pab cuam FTTX. Raws li lub nraub qaum ntawm cov kev sib txuas lus sib kis, tiv thaiv kev cuam tshuam thiab tiv thaiv hluav taws xob cov yam ntxwv ntawm cov hluav taws xob optical tau zoo dua rau lub neej yav tom ntej ntawm tib neeg cov ntaub ntawv, muaj qhov raug siab, thiab tus nqi qis, yog li cov kis nruab nrab ntawm optical fiber tuaj yeem dav ntxiv Cov. Cov. Tab sis kuj sib tham, fiber-rau-lub tsev yuav tsum nrov heev, thiab tseem muaj ntau yam teeb meem yuav tsum daws, xws li thev naus laus zis ntawm kev sib kis thiab txais qhov kawg thiab cov khoom siv, nrog rau kev ceev ntawm cov kis, txawm hais tias nws tuaj yeem hais txog qhov kev nrawm ntawm G bytes, tab sis rau tus neeg siv, kev ua cov ntaub ntawv loj yuav tsum muaj lub khoos phis tawm zoo dua. Yog li, kev txhim kho ntawm kev sib txuas lus nyob ntawm qee yam ntawm kev tsim kho sai ntawm cov thev naus laus zis thev naus laus zis.
OPTICO KEV SIB TXUAS LUS muab tag nrho FTTH kev daws teeb meem hauv cov khoom zoo thiab cov nqi sib tw.
