Fiber Optic Nkag Network Yuav Yog Lub Zog Loj Ntawm Cov Ntaub Ntawv Hluav Taws Xob Tshaj Tawm Hauv Tebchaws Tom Ntej
Raws li nrog txoj kev loj hlob sai ntawm cov ntaub ntawv sib raug zoo, fiber ntau thev naus laus zis thev naus laus zis thiab cov khoom siv uas tau mob siab muab kev hloov chaw ntawm kev lag luam tshiab rau WAN thiab fiber optic nkag network. Kev tsim kho ntawm MSTP thiab PON yog tus neeg sawv cev tshaj plaws. Lawv kuj yog qhov kev daws teeb meem zoo tshaj plaws los muab ntau yam lag luam tshiab hauv MAN thiab fiber optic nkag network uas yog ua raws li cov tshuab xa xov fiber ntau. Raws li dej rau cov ntses, kev tsim kho ntawm fiber ntau optic nkag technology tsis tuaj yeem tsis muaj kev txhawb nqa thiab kev tsim kho cov khoom siv hluav taws xob fiber ntau.
Vim los ntawm kev txhim kho fiber ntau optic nkag mus siv technology thiab ntau thiab ntau ntxiv ntawm cov tuam txhab nkag, tam sim no cov khoom siv fiber optic nkag mus hauv pawg muaj ntau dua thiab pom tseeb, feem ntau muab faib ua peb pawg:
Fiber optic txuas cov ntsiab lus, nws tau thov rau hauv kev sib txuas lus thiab khoos phis tawj sib txuas lub davhlau ya nyob twg, muaj cov khoom lag luam: Cov kab hluav taws xob optic thaj cable, fiber ntau txuas ua ke thiab lwm yam.
Fiber optic transceiver, nws yog siv rau khoos phis tawj network cov ntaub ntawv xa mus, cov khoom lag luam muaj feem xyuam: Fiber optic splitter, fiber ntau thaj ua rau thaj thiab lwm yam.
Cov tshuab hluav taws xob fiber optic thiab cov khoom siv hluavtaws fiber ntau, nws yog qhov tshwj xeeb rau kev ua haujlwm loj, muaj feem rau cov khoom lag luam: Fiber optic fusion splicer, fiber optic testers.
Tom ntej no peb yuav qhia peb qhov kev siv ua fiber ntau rau cov khoom siv nrog tus sawv cev khoom feem, lawv yog cov kab hluav taws xob cov xov tooj hluav taws xob, fiber ntau optic splitter, fiber ntau optic fusion splicer.
Fiber optic thaj cable (qhia raws li daim duab） yog fiber ntau cable lossis fiber ntau kho qhov muag uas tsis muaj qhov txuas hluav taws xob fiber ntau, nws siv nyob rau hauv fiber ntau faib ua ke ntawm ntau txoj kev txuas. Fiber fiber thaj cables tseem siv nyob rau hauv deb deb hauv zos kho qhov muag network, cov ntaub ntawv kev sib kis thiab cov network ntiag tug, ntau yam kev sim thiab kev tswj hwm.
Fiber optic splitter （qhia raws li daim duab), ib tug neeg hu nws ua fiber ntau txuas, nws yog rau cov khoom siv kho qhov muag passive, nws yog siv nyob rau hauv kev sib txuas lus hauv xov tooj, fiber ntau cable TV tes hauj lwm, lub voj voos tub luam. Fiber optic splitters tuaj yeem muab faib ua cov qauv txuas (ob ceg, chav tsev 1 x 2, uas yog, lub teeb liab hluav taws xob mus rau ob lub zog, piv txwv li, 1 × 2 fiber ntau optic splitter, 1 x4 fiber ntau optic splitter, 1 x 8 fiber ntau optic splitter thiab ntxiv mus), lub hnub qub / tsob ntoo fiber ntau splitters thiab wavelength faib multiplexer (WDM, yog hais tias lub yoj yoj yog qhov siab sib cais thiab sib zog yoj yoj yov yog nqaim, nws belongs DWDM).
Fiber optic fusion splicer （qhia raws li daim duab) yog siv dav hauv kev sib txuas lus rau fiber ntau kho qhov muag thiab kev tsim kho, nws tau siv rau hauv kev sib txuas lus hauv kev sib txuas lus, cov tuam txhab tsim khoom, tuam txhab tsim ntiag tug, kuj siv hauv kev tsim cov khoom lag luam passive thiab nquag siv thiab fiber ntau kho qhov muag. modules rau fiber ntau splicing.
Tag nrho cov saum toj no cov khoom siv fais fab fiber ntau txhim kho cov ntaub ntawv xa khoom thiab kev ua tiav ntawm fiber optic nkag network, thiab tib lub sijhawm lawv tuaj yeem nqa ob qho zoo:
Ua ntej, nws daws qhov teeb meem kev xa mus ntev ntawm cov kab fiber ntau txuas, thiab ua kom nws cov kev pab them nqi dav dua. Nyob rau hauv txoj kev no, tom qab ntawd nws tuaj yeem txo qis cov naj npawb ntawm kev hla mus los ntawm tag nrho cov kev pab cuam pov hwm, ua kom cov qauv hauv lub network tau yooj yim.
Thib ob, nws txaus siab cov neeg xav tau ntau yam lag luam dav dav, thiab txhim kho qhov ua tau zoo ntawm cov ntaub ntawv lag luam tshiab. Nws daws qhov teeb meem ntawm cov tsoos tooj liab cable nkag network lub hauv paus thiab tau teeb tsa lub hauv paus zoo rau kev ua tiav qhov kev npau suav ntawm FTTH. Kuv ntseeg hais tias yav tom ntej, fiber optic nkag network yuav yog lub zog loj ntawm cov ntaub ntawv kev tsheb ceev hauv internet.
