Fiber Optic Splitters - Hom Ntau
Cov fiber ntau tawg tau ua kom lub teeb liab ntawm qhov kho qhov muag kom faib tau ntawm ob lossis ntau daim phiaj. Txij li cov txiav tawm tsis muaj cov khoom siv hluav taws xob tsis yog yuav tsum tau siv lub zog, lawv yog cov tseem ceeb thiab siv dav hauv cov kab hluav taws xob fiber ntau. Raws li tus piv txwv yooj yim, daim duab hauv qab no qhia tau hais tias yuav ua li cas lub teeb rau hauv ib qho fiber ntau nkag tuaj yeem faib nruab nrab ntawm plaub tus xov tooj (1x4):
Splitters tuaj yeem tsim tau siv ntau hom ntawm tib hom thiab multimode optical fibers thiab nrog rau feem ntau txuas hom rau ntau daim ntawv thov.
Los ntawm cov thev naus laus zis pom, muaj ob qhov kev siv hluav taws xob feem ntau siv:
Fused Biconic Tapered (FBT) Hmoob
Cov Kev Npaj Phom Sij Teeb (PLC)
Raws li nrog feem ntau cov thev naus laus zis, txhua hom muaj ob qho zoo thiab qhov tsis zoo thaum uas siv lawv rau hauv qhov kev ntsuas siab dhau mus.
Fused Biconic Tapered Splitters
FBT yog qhov qub thev naus laus zis nyob rau hauv uas ob lub fiber ntau tau muab tso ua ke thiab sib txuas ua ke los ntawm kev thov tshav kub thaum lub rooj sib txoos ua elongated thiab tapered. Ib lub teeb liab tau siv los txiav txim siab txog qhov taw tes ntawm qhov sib piv uas xav tau txuas tau, uas tom qab ntawd nres cov txheej txheem.
Raws li cov thev naus laus zis no tau tsim kho thaum lub sijhawm, qhov zoo ntawm FBT splitters tau zoo heev thiab lawv tuaj yeem xa tawm mus rau qhov tsis raug nqi. FBT splitters tau dav txais thiab siv nyob rau hauv kev sib koom ua ke, tshwj xeeb rau kev piv txwv qhov sib cais kev teeb tsa me dua (1x2, 1x4, thiab lwm yam).
Ib qho tsis zoo ntawm cov cuab yeej no tshwm sim thaum muaj kev sib cais loj (1x16, 1x32, 1x64, thiab lwm yam). FBT thev naus laus zis yog txwv nyob rau hauv cov xov tooj ntawm qhov zoo sib cais uas tuaj yeem ua tiav hauv ib qho piv txwv, yog li ob peb yuav tsum tau spliced ua ke thaum yuav tsum tau sib cais loj tshaj qhov yuav tsum tau ua. Raws li qhov ua tiav, lub cev nce ntxiv vim muaj ntau qhov sib cais, nrog rau cov kev ploj ntau dua los ntawm cov splices. Yog li, rau cov xwm txheej zoo li no, PLC splitter yog qhov zoo tshaj li peb yuav tham hauv tshooj lus tom ntej.

Planar Lightwave Circuit Splitters
Ib lub thev naus laus zis ntau dua, PLC splitters muaj cov tshuaj zoo dua rau cov ntawv thov uas qhov loj cais kev teeb tsa yuav tsum ua. Yuav kom ua tiav qhov no, waveguides yog kev qhia siv lithography mus rau silica iav substrate, uas tso cai rau kev qhia feem pua ntawm cov teeb. Raws li qhov tshwm sim, PLC splitters muaj qhov tseeb heev thiab txawm tias muaj kev sib cais nrog txoj kev poob qis hauv ib lub pob siv tau zoo.
Nrog txoj kev loj hlob sai ntawm FTTx thoob ntiaj teb, qhov yuav tsum muaj rau kev sib cais loj dua (1x32, 1x64, thiab lwm yam) hauv cov tes hauj lwm no tau loj hlob ntxiv kom tau txais kev pab loj. Vim tias qhov txiaj ntsig ntawm kev ua tau zoo thiab tag nrho tus nqi qis rau xa mus, PLC splitters yog tam sim no cov kev daws teeb meem zoo rau cov kev siv no.
