Yuav Xaiv Tau Li Cas ntawm PLC & FBT Fiber Optic Splitters?
Hauv FTTx thiab PON architectures, fiber ntau optic splitter yog ib qho tseem ceeb los qhia cov optic network nrog ntau cov neeg siv. Lub hauv paus ntsiab lus ntawm fiber ntau optic splitter yog cais ib qho optic lub teeb nqaj mus rau ntau qhov chaw ntawm qhov sib piv. Raws li kev tsim khoom sib txawv ntawm cov thev naus laus zis, cov fiber ntau hluav taws xob tuaj yeem muab faib ua PLC splitter thiab FBT splitter. Tej zaum koj yuav xav paub qhov sib txawv ntawm ob hom kev sib cais thaum ua kev xaiv ntawm lawv. Kab lus no tsuas yog pab koj kom nkag siab txog lawv cov kev sib txawv thiab txiav txim siab tau zoo dua.
PLC hais txog cov phiaj xwm hluav taws xob xov hluav taws xob. Raws li qhov khoom siv micro-kho qhov muag, PLC splitter siv lub tshuab hluav taws xob zoo kom faib cov teeb liab tawm tswv yim mus rau ntau qhov kev tawm suab. Ntawm ntug ntawm lub nti, muaj lub teeb hluav taws xob nyob hauv daim npav pob tsa ua ke ntawm cov cab kuj thiab xov tooj. PLC splitter feem ntau adopts silica iav raws li cov khoom ntawm lub teeb hluav taws xob Circuit Court thiab lees txais ntau hom polished tiav. Qhov hauv qab, waveguide thiab lub hau yog peb txheej txheej ntawm PLC splitter. Rau cov ntawv thov sib txawv, PLC splitters tuaj yeem txuas ntxiv rau ntau hom sib txawv nrog rau pliaj PLC splitters, blockless PLC splitters, ABS PLC splitters, LGX kem PLC splitters, mini ntsaws hom PLC splitters, tais hom PLC splitters thiab 1U khib mount PLC splitters.
FBT, lossis fused biconic taper siv cov thev naus laus zis niaj hnub siv los tshuab ntau cov ua ke. Cov fibers yog mus raws li cua sov rau qhov chaw nyob thiab ntev. Cov txheej txheem kev sib txuas yuav tsis nres mus txog thaum cov tsis ua ntawm cov fibers mus txog qhov qauv xav tau. Txij li cov xov fused yog cov puas yooj yim heev, lawv muaj kev tiv thaiv los ntawm lub iav raj ua los ntawm epoxy thiab silica hmoov. Tom qab ntawd ib tus pas hlau tsis xeb npog lub iav raj sab hauv thiab raug kaw los ntawm silicon. FBT splitter nrog ABS lub thawv kuj yog dav siv rau cov ntawv thov sib txawv.
PLC thiab FBT splitters zoo li sib thooj, tsis tas li lawv tseem muaj ntau yam sib txawv thaum nws los txog rau cov ntawv thov tiag tiag. Ntawm no yuav piv lawv ntawm ntau yam.
Txoj kev sib cais txiav txim siab yog txiav txim siab los ntawm kev txiav txim thiab qhov tawm ntawm cov tshuab ntsaws. PLC splitter yog muaj nyob nrog cov kev faib tawm sib piv ntawm 1:64, uas txhais tau tias ib qho nqaj teeb muaj peev xwm muab sib cais ua 64 qhov sib tshooj ntawm ib zaug. Txawm li cas los xij, FBT splitter feem ntau yog siv rau cov tes hauj lwm uas xav tau cov kev cais tsim tsawg dua 4 qhov sib cais. Thaum nws qhov kev faib ua feem loj dua li 1: 8, ntau qhov yuam kev yuav tshwm sim thiab ua rau qhov ua haujlwm siab dua. Yog li, FBT splitter ntau txwv rau cov lej ntawm kev sib cais hauv ib qho txuas.
PLC splitter muaj qhov dav dua li khiav hauj lwm wavelength los ntawm 1260 nm txog 1620 nm, yog li nws tuaj yeem siv rau feem ntau ntawm cov ntawv thov hauv FTTx thiab PON tes hauj lwm. Ntawm qhov tsis sib xws, FBT splitter muaj qhov txwv tsuas yog siv tau rau 850nm, 1310nm thiab 1550nm wavelengths. Qhov no ua rau tsis muaj kev cuam tshuam ntawm FBT splitter rau lwm cov wavelengths.
Kev ntsuas kub tsis taus (TDL) ntawm qhov ntsaws yog cuam tshuam los ntawm cov txheej txheem tsim tawm thiab cov rhiab ntawm cov twj. Thaum ua haujlwm qhov kub thiab txias ntawm cov splitter tawm ntawm ntau qhov, tso tsis tau ntxig yuav nce thiab cuam tshuam rau kev ua tau zoo ntawm splitter. PLC splitter tuaj yeem ua haujlwm ntawm qhov kub ntawm -40 txog 85 Celsius degrees thaum FBT splitter tsuas tuaj yeem ua haujlwm ntawm -5 txog 75 Celsius degrees.
Muaj feem rau qhov nyuaj tsim thev naus laus zis ntawm PLC splitter, nws cov nqi yog feem ntau siab dua FBT hom. Yog tias koj daim ntawv thov tau yooj yim thiab luv luv ntawm pob nyiaj, FBT splitter yog cov nqi twv yuav raug nyiaj.
Hauv tsab xov xwm no, qee qhov sib txawv ntawm PLC thiab FBT splitters tau qhia kom pab koj xaiv qhov uas haum tshaj plaws rau koj lub network. Zuag qhia tag nrho, PLC splitter muaj cov kev ua tau zoo dua qub thiab muaj tsawg dua kev txwv, tab sis FBT splitter tsis kim dua los txuag ntau rau cov peev nyiaj. Yog tias koj tseem tsis tau paub meej uas yuav xaiv, thov sab laj tus kws tshaj lij kom pab.
