Optical access network (uas yog, nkag tau network nrog lub teeb raws li qhov nruab nrab kis tau tus mob, es tsis txhob ntawm tooj liab hlau, yog siv los nkag rau txhua tsev neeg. Optical access network).Optical access network feem ntau muaj peb ntu: kho qhov muag kab davhlau ya nyob twgOLT, optical network unitONU, optical faib networkODN,hauv qhov twgOLT thiabONUyog cov tseem ceeb ntawm optical access network
OLTstands rau Optical Line Terminal.OLTyog qhov kho qhov muag kab davhlau ya nyob twg, yog cov khoom siv hauv kev sib txuas lus hauv chaw ua haujlwm, siv los txuas cov kab hluav taws xob kho qhov muag, lub luag haujlwm yog sib npaughloovor routernyob rau hauv ib txwm kev sib txuas lus network, yog ib tug ntaus ntawv rau sab nraud network nkag thiab internal network nkag. Muab tso rau ntawm qhov kawg hauv zos, cov thawj coj tseem ceeb tshaj plaws yog kev teem caij tsheb, kev tswj tsis tau, thiab muab cov neeg siv ntsib passive fiber ntau network interface thiab faib cov bandwidth. Yooj yim muab tso, nws yog ua kom tiav ob txoj haujlwm, nce toj, ua kom tiav kev nkag mus ntawm PON network; Hauv qab, cov ntaub ntawv tau txais raug xa mus rau txhua tusONUcov neeg siv khoom siv davhlau ya nyob twg los ntawm ODN network.
ONUyog Optical Network Unit.ONUmuaj ob lub luag haujlwm: xaiv tau txais kev tshaj tawm xa los ntawmOLT, thiab tau txais cov lus teb rau covOLTyog tias cov ntaub ntawv yuav tsum tau txais; Sau thiab cache cov ntaub ntawv Ethernet uas tus neeg siv yuav tsum xa, thiab xa cov ntaub ntawv cached mus rauOLTdavhlau ya nyob twg raws li lub qhov rais xa.
Ntawm FTTx network (nias ntawm no Kom paub ceev ceev txog FTTx), lubONUhom nkag mus sib txawv nrog rau kev xa tawm sib txawv. Piv txwv li, Fiber To The Curb (FTTC): TusONUyog muab tso rau hauv cov khoom siv hauv nruab nrab ntawm lub cell. FTTB (Fiber rau Lub Tsev):ONUmuab tso rau hauv lub thawv davhlau ya nyob twg ntawm txoj kev hauv tsev; FTTH (Fiber Rau Lub Tsev): LubONUmuab tso rau hauv tus neeg siv hauv tsev.
OLTyog lub davhlau ya nyob twg tswj,ONUyog lub davhlau ya nyob twg; Qhov kev pab qhib ntawmONUyog xa los ntawmOLT, thiab kev sib raug zoo ntawm ob yog tus tswv- qhev. NtauONUstuaj yeem txuas rau ib qhoOLTlos ntawm ib tug splitter.
ODN yog Optical Distribution Network, optical tis network, lub cev channel ntawm optical kis tau tus mob ntawmOLTthiabONU. Nws lub luag haujlwm tseem ceeb yog ua kom tiav bidirectional kis tau tus mob ntawm optical signals. Nws feem ntau yog tsim los ntawm optical fiber ntau thiab cable, optical connector, optical splitter, thiab auxiliary khoom rau nruab thiab txuas cov khoom siv no. Ib qho ntawm cov khoom tseem ceeb tshaj plaws yog optical splitter.
HDVtuaj yeem muab cov neeg siv khoom nrog ntau yam ntawm FTTH cov khoom thiab cov kev daws teeb meem. Founded hauv 2012, HDV yog ib qho kev daws teeb meem ib leeg thiab ODM & OEM chaw tsim khoom rau kev siv fiber ntau. Raws li cov kev xav tau ntawm cov neeg siv khoom, peb tuaj yeem pab cov neeg siv khoom tsim cov qauv tsim cov khoom lag luam zoo thiab cov khoom lag luam customized, thiab muab kev pabcuam zoo ODM & OEM. Tau ua raws li tus ntsuj plig ntawm kev sib koom siab, kev ua haujlwm nyuaj, kev tsim kho tshiab, kev ua tau zoo thiab kev ncaj ncees, nrog lub zog R & D kev muaj peev xwm thiab kev xa khoom zoo tshaj plaws, muab cov neeg siv khoom nrog cov khoom siv kho qhov muag fiber ntau sib txuas lus thiab cov kev daws teeb meem, cia peb ua haujlwm. ua ke, yeej-yeej yav tom ntej!
