Tam sim no, nrog kev sib txuas ntxiv ntawm cov kev sib txuas lus fiber ntau, fiber optic splitter ua lub luag haujlwm tseem ceeb hauv ntau ntawm cov niaj hnub no optical network topologies. Txawm hais tias muaj ntau yam sib txawv ntawm cov neeg sib cais, ob txoj kev sib cais feem ntau yog FBT (Fused Biconical Taper) splitter thiab PLC (Planar Lightwave Circuit) splitter. Yog li, thaum koj tso koj lub network, qhov splitter uas koj yuav tsum xaiv yuav yog teeb meem rau koj. Thiab kom daws tau qhov teeb meem no, daim ntawv no yuav muab cov lus qhia ntxaws ntxaws ntawm kev sib txawv ntawm FBT splitter thiab PLC splitter.
Ua ntej koj yuav tsum paub txog cov yam ntxwv ntawm lawv, ua ntej koj yuav tsum paub tias lawv yog dab tsi. Tom ntej no, txhua tus splitter yuav qhia.
FBT Splitter - FBT yog lub thev naus laus zis zoo li qub uas ob txoj xov hlau sib txig sib luag thiab sib txuas ua ke thaum sib sau ua ke yog elongated thiab tapered. Lub xov fused yog tiv thaiv los ntawm lub khob substrate thiab tom qab ntawd tiv thaiv los ntawm cov raj tsis xeb hlau, feem ntau 3 hli txoj kab uas hla los ntawm 54 hli ntev. FBT splitters tau dav txais thiab siv nyob rau hauv passive optical network, tshwj xeeb tshaj yog rau qee qhov twg cov teeb tsa sib cais tsis ntau dua 1 × 4. Qhov tsis zoo ntawm qhov thev naus laus zis yog thaum qhov loj dua kev sib cais xws li 1 × 16, 1 × 32 thiab 1 × 64 yog qhov xav tau.
PLC splitter - PLC splitter yog micro-kho qhov muag raws li planar lightwave Circuit thev naus laus zis thiab muab cov khoom lag luam hluav taws xob pheej yig daws teeb meem nrog daim ntawv me me thiab kev ntseeg siab. Nws yog tsim siv silica iav waveguide circuits uas mus raws li V-groove fiber ntau array uas siv ribbon fiber. Thaum txhua tsav txhua yam los sib dhos thiab sib khi, nws mam li ntim rau hauv chaw me me. PLC Splitter muaj qhov ua tau zoo, xws li poob qis tsis txaus, PDL tsawg (Kev poob siab ntawm qhov tsis tau), siab rov qab poob thiab zoo tshaj plaws rau qhov sib txawv dhau qhov dav dav ntawm 1260 nm txog 1620 nm thiab muaj qhov kub ua haujlwm -40 ° C txog +85 ° C.
Hauv ob peb xyoos dhau los, kev siv tshuab txaws tau ua rau cov kauj ruam loj dua, tshwj xeeb tshaj yog PLC splitter technology. Cov xwm txheej no tau ua rau PLC splitter tau dhau los ua cov cuab yeej siv tau zoo dua piv rau cov tsoos FBT splitter. Txawm hais tias ua zoo ib yam nkaus ntawm qhov loj me thiab tsos, sab hauv ntawm cov thev naus laus zis tom qab cov hom no sib txawv, yog li ua rau cov chaw muab kev pabcuam muaj peev xwm xaiv txoj kev daws teeb meem zoo dua.
Kev khiav hauj lwm Wavelength - Raws li tau hais los saum no, PLC splitter tuaj yeem muab ntau ntawm kev khiav hauj lwm wavelength los ntawm 1260 nm txog 1620 nm. Tab sis FBT splitters tsuas yog txhawb nqa peb nthwv dej (850/1310/1550 nm) uas ua rau cov cuab yeej no tsis tuaj yeem ua haujlwm ntawm lwm lub yoj hluav taws xob.
Kev Ua Haujlwm Kub - Feem ntau, FTB splitter yog rau qhov kub siab txog qhov kub thiab txias, muab qhov chaw ua haujlwm ruaj khov ntawm -5 ° C txog 75 ° C. Thaum PLC splitter ua haujlwm nyob ntawm qhov dav qhov kub thiab txias (-40 ° C txog 85 ° C), tso cai rau nws siv rau thaj tsam ntawm huab cua tsis zoo.
Sib Piv Piv - Qhov sib piv ntawm FBT splitter yog 1: 8 thiab nws tuaj yeem ua tau ntau dua nrog cov nqi tsis ua haujlwm siab dua. Qhov sib faib ua feem ntawm PLC splitter tuaj yeem mus txog 64, uas yog sib npaug nrog txhua ceg, yog li muab qhov kev ntseeg siab.
Nqi - FBT splitter yog tsim tawm ntawm cov ntaub ntawv uas yooj yim muaj, piv txwv li hlau, fiber, dorm kub thiab lwm yam. Txhua yam ntawm cov khoom siv no tus nqi qis, uas txiav txim siab tus nqi qis ntawm lub cuab yeej nws tus kheej. PLC splitter manufacturing technology ntau nyuaj. Nws siv cov thev naus laus zis thev naus laus zis (lithography, etching, tsim tawm tshuab) ntau lawm, yog li nws nyuaj rau kev tsim khoom. Yog li ntawd, tus nqi ntawm cov cuab yeej no yog siab dua.
Hauv ib lo lus, Piv nrog FBT splitter, lub peev xwm ntawm PLC splitter yog qhov zoo dua, tab sis kim dua tus FBT splitter hauv cov kev sib piv me me. Koj tuaj yeem xaiv nws raws li koj qhov yuav tsum tau ua. FOCC muaj ob qho FBT splitter thiab PLC splitter nrog cov khoom zoo thiab tus nqi qis. Txawm nyob hauv FTTx lub tshuab lossis hauv lub vev xaib optic network, FOCC splitter tuaj yeem pab koj kom ua tiav qhov kev ua haujlwm ntawm optical network circuits.
