Koj puas paub txog Fiber Optic Splitter?
Niaj hnub no nyob rau hauv optical network topologies, kev tawm tswv yim ntawm fiber ntau optic splitter tseem ceeb hauv kev pab cov neeg siv ntau tshaj qhov ua tau zoo ntawm optical network circuits. Fiber optic splitter, lossis qee zaum hu ua beam splitter, yog qhov ua kom qhov ntsej muag sib cais uas tuaj yeem sib cais qhov teeb meem teeb pom kev zoo mus rau ob lossis ntau ntau lub teeb ci ntsa iab, thiab rov ua dua. Cov cuab yeej muaj ntau cov tswv yim thiab cov zis xaus. Thaum twg lub teeb xa hluav taws xob hauv lub network xav tau muab faib, fiber ntau optic splitter tuaj yeem siv rau qhov yooj yim ntawm kev sib koom tes sib txuas.
Raws li rau txoj haujlwm ua haujlwm ntawm fiber optic splitter, nws tuaj yeem piav qhia raws li txoj kev hauv qab no. Thaum lub teeb liab teeb liab kis mus rau hauv ib hom fiber ntau, lub teeb lub zog tsis tuaj yeem koom nrog cov tub ntxhais fiber ntau. Qhov hluav taws xob me me yuav kis tau los ntawm kev tuav cov fiber. Qhov ntawd yog hais, yog tias ob lub fiber ntau sib kis ze rau ib leeg, qhov teeb meem kis hauv lub teeb tsa hluav taws xob tuaj yeem nkag mus rau lwm qhov kho qhov muag. Yog li no, cov txheej txheem kev hloov chaw tiag tiag ntawm lub teeb liab kho tau zoo tuaj yeem ua tiav hauv ntau cov fibers. Thiab qhov no yog li cas fiber ntau optic splitter los ua ua.
Tam sim no, muaj ob yam ntawm cov xov hluav taws xob fiber ntau faib ua. Ib qho yog lub npe hu ua PLC (planar lightwave Circuit) splitter, thiab lwm qhov yog hu ua FBT (fused biconical taper) splitter.
1) PLC splitter faib cov teeb liab nkag mus rau hauv ntau cov txiaj ntsig los ntawm kev siv optic splitter nti. Ib qho optic splitter nti tuaj yeem ua tiav ntawm qhov feem ntau 64 xaus. PLC splitter feem ntau yog siv rau cov ntawv thov loj dua. Kev poob ntawm PLC splitter tsis cuam tshuam rau nthwv dej, uas ua rau kom muaj kev xav tau ntau yam kev xa xov wavelengths. PLC splitter lub configuration yog compact thiab nws qhov loj me me, yog li qhov chaw teeb tsa tau txuag tau zoo.
2) FBT splitter yog fused nrog cov cua kub zoo ib yam li qhov ib-rau-ib qhov kev sib cais. Fibers yog ncab hauv qab cua sov los ua ob lub khob hliav qab. Tus nqi ntawm FBT splitter tsawg dua vim yog cov khoom siv feem ntau siv, thiab qhov sib cais feem ntau yog kho tau. Tab sis cov poob yog rhiab rau wavelengths. Cov cuab yeej yuav tsum xaiv raws li wavelengths. Thiab nws tsis muaj peev xwm muab cov teeb tsa zoo li sab hauv.
1) Kev soj ntsuam daim ntawv cog lus ntawm fiber ntau optic splitter yog siv rau kev kho lub network ntev, cable TV ATM Circuit Court lossis thaj tsam hauv cheeb tsam / xov tooj hauv cheeb tsam. Lub tshuab splitter mus rau hauv feem pua me me ntawm cov kis teeb meem. Feem ntau ntawm cov teeb liab tuaj txog nws qhov chaw kawg, tab sis feem pua me me tau qhia rau lub chaw nres nkoj hauv zos. Daim ntawv thov tuaj yeem ua tau los ntawm kev siv haujlwm ua haujlwm rau cov teeb meem daws teeb meem lossis los ntawm kev sib txuas lub tshuab ntsaws mus rau lub chaw soj ntsuam xyuas lub network rau kev tu thiab kev ntsuas.
2) Fiber optic splitter kuj tseem siv tau rau FTTx / PON thov. Qhov no ua rau kom txo tau lub cev siv fiber ntau lossis qhov pib qhov ntau ntawm cov muaj fiber ntau. Ib qho fiber ntau tau muab faib ua ntau ceg kom txhawb ntau cov neeg siv khoom kawg. Txoj kev nyuaj ntawm lub ntsej muag fiber ntau tuaj yeem txo qis los ntawm kev thov.
Txhawm rau suav, fiber ntau optic splitter muab kev daws rau kev txhim kho cov ua tau zoo ntawm kho qhov muag tsim kho. PLC splitter thiab FBT splitter muaj ntau yam nyob rau ntau qhov sib txawv, yog li xaiv qhov zoo hom splitter rau koj lub network kuj tseem ceeb. FOCC muab tag nrho cov saum toj no fiber ntau optic splitters. Thov saib FOCC kom paub ntaub ntawv ntau ntxiv.
