Txawv ntawm FBT Splitter thiab PLC Splitter
Hauv FTTx thiab PON architectures, optical splitter plays lub luag haujlwm tseem ceeb los tsim kom muaj ntau yam tes taw-rau-multipoint fiber optic tes hauj lwm. Tab sis koj puas paub dab tsi yog qhov fiber optic splitter? Qhov tseeb, ib qho fiber optic splitter yog ib qho khoom siv kho qhov muag uas yuav faib tau lossis cais cov teeb meem ntawm qhov teeb pom kev rau hauv ob lossis ntau dua. Yeej, muaj ob hom fiber ntau splitter cais los ntawm lawv txoj haujlwm ua haujlwm: fused biconical taper splitter (FBT splitter) thiab planar teeb pom kev zoo circuit splitter (PLC splitter). Koj yuav muaj ib lo lus nug: qhov txawv ntawm lawv thiab peb puas yuav siv FBT lossis PLC splitter?
FBT Splitter yog dab tsi?
FBT splitter yog ua raws li cov cuab yeej siv los ua kom muaj ntau cov fiber ntau ua ke los ntawm ib sab ntawm cov fiber ntau. Cov fibers yog mus raws li cua sov rau ib qho chaw thiab ntev. Vim tias cov fused fused muaj zog heev, lawv muaj kev tiv thaiv los ntawm ib lub khob raj ua los ntawm epoxy thiab silica hmoov. Thiab ces ib txoj hlua hlau tsis txhuam cov iav hauv qab thiab iav los ntawm silicon. Raws li kev siv cuab yeej ua ke, qhov zoo ntawm FBT splitter zoo heev thiab nws tuaj yeem siv rau txoj kev siv nyiaj.

PLC Splitter Yog Dab Tsi?
PLC splitter yog tsim raws li cov qauv kev teeb tsa ntawm circarf circuit. Nws tau tsim ntawm peb txheej: ib qho substrate, waveguide, thiab ib lub hau. Lub waveguide plays lub luag haujlwm tseem ceeb hauv txoj kev splittering uas tso cai rau kev xa cov feem pua ntawm lub teeb. Li ntawd, lub teeb liab thiaj li faib tau qhov sib npaug. Tsis tas li ntawd, PLC splitters muaj ntau ntau qhov kev cais, xws li 1: 4, 1: 8, 1:16, 1:32, 1:64, thiab lwm yam. Lawv muaj ob peb hom, xws li liab qab PLC splitter, PLC splitter, fanout PLC splitter, Mini plug-in type PLC splitter, thiab lwm yam. Yog li no, yog cov khoom phua siab yuav tsum tau, me me pob thiab tsawg insertion poob tseem ceeb, koj tau pom tias yuav xaiv PLC splitter ntau dua li FBT splitter. Yog xav paub ntxiv txog PLC splitter, thov saib ntau npaum li cas Koj Puas Paub Txog PLC Splitter?

FBT thiab PLC Splitter
(1) Kev Haujlwm Wavelength
FBT splitter tsuas pab tau peb lub wavelengths: 850nm, 1310nm thiab 1550nm, uas ua rau nws tsis muaj peev xwm ua haujlwm rau lwm lub wavelengths. Thaum PLC splitter pab txhawb wavelength ntawm 1260 txog 1650nm. Qhov hloov ntawm lub wavelength ua PLC splitter tsim rau ntau daim ntawv sau npe.
(2) Txoj Kev Txiav Txim Siab
Splitting ratio yog txiav txim siab los ntawm kev siv thiab kev tawm ntawm kev kho qhov muag cable. Qhov siab tshaj cais ntawm FBT splitter yog li 1:32, uas txhais tau hais tias ib los yog ob qho khoom siv yuav raug muab faib rau hauv ib qho kev tshaj plaws ntawm 32 fibers ib zaug. Txawm li cas los xij, qhov faib cais ntawm PLC splitter yog li 1:64 - ib lossis ob txoj kev siv nrog cov zis kawg ntawm 64 fibers. Dhau li, FBT splitter yog customizable, thiab qhov tshwj xeeb hom yog 1: 3, 1: 7, 1:11, thiab lwm yam. Tab sis PLC splitter yog non-customizable, thiab nws muaj tsuas standard version zoo li 1: 2, 1: 4, 1 : 8, 1:16, 1:32 thiab lwm yam.
(3) Kev Ntsuas Kev Nyuaj Siab Ib Ntu
Qhov teeb liab uas ua los ntawm FBT splitters tsis tuaj yeem muab faib rau ntawm qhov tsis muaj kev tswj ntawm qhov pib, vim li ntawd nws txoj kev kis mus rau lwm tus tuaj yeem cuam tshuam. Txawm li cas los xij, PLC splitter tuaj yeem pab txhawb kev sib txig sib luag rau txhua ceg, yog li nws ruaj khov dua.
(4) Tsis Ncaj Ncees
FBT splitter feem ntau yog siv rau tes hauj lwm xav tau qhov kev cais ntawm qhov tsawg tshaj li 4 seem. Qhov loj dua qhov faib, qhov loj dua tus nqi. Thaum nws txoj kev sib faib nruab nrab yog ntau dua li 1: 8, ntau cov teeb meem yuav tshwm sim thiab ua rau tsis ua hauj lwm dua. Yog li, FBT splitter muaj ntau txwv kom muaj pes tsawg tus cais nyob hauv ib qho kev sib koom tes. Tab sis qhov tsis ua hauj lwm tus nqi ntawm PLC splitter ntau me me.
(5) Kub Ntshe Kev Kub Siab
Hauv qee thaj chaw, qhov kub thiab txias tuaj yeem yog qhov tseem ceeb tshaj uas cuam tshuam txog kev nkag ntawm qhov chaw seem ntawm qhov muag. FBT splitter tuaj yeem ua haujlwm ruaj khov nyob rau ntawm qhov ntsuas ntawm -5 mus rau 75 ℃. PLC splitter tuaj yeem ua haujlwm ntawm qhov chaw kub siab tshaj ntawm -40 mus rau 85 ℃, muab kev ua haujlwm zoo rau cheeb tsam huab cua.
(6) Nqe
Rov qab rau kev siv technology ntawm PLC splitter, nws cov nqi feem ntau siab tshaj FBT splitter. Yog tias koj daim ntawv thov tau yooj yim thiab qee cov nyiaj, FBT splitter yog qhov tseeb ntawm kev siv nyiaj.
Xaus
Txawm hais tias qhov tsos thiab qhov loj ntawm FBT thiab PLC fiber ntau splitter zoo li qhov zoo sib xws, lawv cov yees nyob hauv thiab cov lus qhia txawv ntawm ntau txoj kev. Tshaj li ob peb xyoos dhau los, splitter technology tau ua ib qho loj loj rau pem ob lub xyoo dhau los ntawm kev qhia PLC splitter. Nws tau pov thawj nws tus kheej ua ib hom kev ntseeg ntau dua rau ntawm qhov kev hloov FBT ib txwm.
