Ntau Cov Txheej Txheem ntawm Fiber Optic Splitter nrog Cov Zoo thiab Tsis Zoo
Fiber optic splitter (optical splitter) kuj muaj lub npe hu ua "non-wavelength selective optical branching device". Nws yog ib qho khoom siv hluav taws xob uas siv los ua kom tiav ib qho kev sib tw ua qhov teeb meem ntawm qhov hluav taws xob fais fab thiab rov faib dua.
Optical splitter yuav siv tau los ua ib qho cuab yeej ntawm stand-alone nyob hauv OLT ntawm, lub teeb taw rau lub teeb thiab FTTH taw tes. Nws tuaj yeem muab tso rau hauv chaw ua haujlwm hauv chaw ua haujlwm hauv chaw ua hauj lwm, cov teeb meem faib cov teeb meem thiab FTTH cov ntsiab lus nyob rau hauv qhov chaw (kev tsim qauv lossis plug-in).
Raws li cov txheej txheem ntau lawm, optical splitters tau muab faib ua Fused Bi-conical Taper (FBT Splitter) thiab Planar Lightwave Circuit (PLC Splitter).
FBT Splitter (FBT Coupler)
Fused Bi-conical Taper cov txheej txheem yog khi rau ob lossis ntau tshaj lij fibers, thiab tom qab ntawd khoob hauv lub tshuab siv lub khob, rub tawm thiab ntsuas lub sij hawm ntawm cov kev hloov hauv kev sib faib, kev sib faib ua kom tau raws li qhov yuav tsum tau tom qab xaus ntawm lub kaum hli ncab, thiab nyob rau ntawm ib qho kawg ntawm qhov khoom siv fiber optic (Cov seem uas txiav tawm) raws li lub davhlau ya nyob twg thiab lwm qhov kawg ntawm ntau ntau txoj kev tawm kev. Mature tapering txheej txheem tsuas yog rub 1 × 4. 1 × 4 los yog ntau tshaj li, nrog ntau tus 1 × 2 txuas ua ke. Tom qab ntawd tag nrho pob nyob rau hauv lub thawv cais.
Zoo Tshaj Plaws
(1) rub tawm qhov sib tw txav ntau tshaj li ntawm nees nkaum xyoo dhau los thiab kev kawm, ntau cov cuab yeej thiab cov txheej txheem tsuas ua raws li tsuas yog cov nyiaj txiag tsuas yog ob peb yam ntawm PLC thib kaum los yog pua ntawm ob peb
(2) Cov ntaub ntawv nyoos tsuas yog muaj quartz substrate, fiber ntau optics, cua kub ntswj tubing, stainless hlau yeeb nkab thiab tsawg dua qub, tag nrho tsis ntau tshaj $ 1. Cov cuab yeej ua lag luam thiab cov khoom siv nqi tsis muaj nqi, 1 × 2,1 × 4 thiab lwm cov khoom lag luam uas tsis tshua muaj nyiaj tsawg.
(3) splitting ratio yuav real-time xyuas, koj muaj peev xwm tsim tau qhov txawv nruab nrab.
Disadvantages
(1) Tsis muaj teeb meem ntawm lub teeb ntawm lub teeb ntom nkoj raws li lub tshav puam xaiv, nyob rau hauv no triple-ua si thaum siv yog ib qho ua rau neeg tuag, vim qhov ua si ntawm lub teeb ntawm lub teeb ci 1310nm, 1490nm, 1550nm, thiab lwm yam teeb meem ntau-wavelength.
(2) pluag uniformity, 1 × 4 nominal txog 1.5dB deb, 1 × 8 los sis ntau dua ntawm qhov loj, tsis tuaj yeem xyuas cov tsom iav tsom iav, uas yuav cuam tshuam rau kev sib kis zuag qhia tag nrho.
(3) Insertion poob txawv nrog qhov txawv ntawm qhov kub thiab txias (TDL)
(4) multi-demultiplexer (piv txwv li, 1 × 16,1 × 32) ntim yog tus loj, qhov kev cia siab yuav raug txo kom tsawg, qhov chaw teeb tsa yog txwv.
PLC Splitter
Planar waveguide technology yog qhov kho qhov muag ntawm lub tshuab hluav taws xob nrog cov khoom siv hluav taws xob. Lub koom txoos ua tiav rau ntawm tus ntiv tes. Nyob rau ib lub ntiv tes kom mus txog li 1 X 32 splitter, ces, thaum ob qho tag nrho ntawm cov ntawv ntim cov thawv ntawv dav hlau thiab ib qho kev tawm dav hlau feem ntau sib ceg ua ke ntau txoj hlua dig fiber ntau.
Zoo Tshaj Plaws
(1) Kev poob ntawm kev kis tau yog tsis nkag siab rau lub teeb ntawm lub teeb, kom tau raws li kev xav tau ntawm ntau lub wavelengths.
(2) qhov teeb meem tsis sib thooj ntawm lub ntsej muag yuav tsum muab faib rau tus neeg siv.
(3) compact structure, me me, yuav tau ntsia ncaj qha rau hauv lub thawv ntawv uas twb muaj lawm, tsis muaj tus tsim tshwj xeeb tawm ntau qhov chaw rau kev teeb tsa.
(4) tsuas yog ib qho hlua khau channel ua tau ntau dua 32 raws. (5) Cov ntau channel, luv nqi, cov hnub qub yuav ntau dua thiab cuab kev zoo dua qub.
Disadvantages
(1) Ntaus txoj kev tsim cov txheej txheem, cov kev taw qhia siab, lub chip yog ntau lub tuam txhab txawv teb chaws mus monopolize domestic tej pob cov tuam txhab muag khoom tsuas yog tsis tshua muaj pes tsawg.
(2) sib piv rau tus nqi siab dua ntawm Fused Splitter ntau dua ntawm qhov tsis zoo, tshwj xeeb tshaj yog nyob rau hauv cov channel tsawg.
