Yuav Kuaj Li Cas Cov Kev Ua Raws Ntawm Cov Khoom Noj Khoom Haus Fiber
Optical fiber yog qhov pib ntawm peb lub xaib, yog li peb yuav tsum nkag siab nws zoo. Ib yam li ntawd, nws muaj ntau yam ntxwv. Piv txwv, cov cai yooj yim ntawm cov khoom siv fiber ntau suav nrog kev txuas ntxiv, yog li nws yog ib qho ntawm cov qauv pib ntawm kev soj ntsuam fiber ntau. Tseem muaj ntau ntawm cov khoom siv sib thooj, xws li fiber ntau attenuator, fiber ntau kho qhov muag cable, fiber ntau vaj huam sib luag, fiber ntau splitter, thiab lwm yam.
Thaum ua cov kev ntsuas ntsuas txuas mus ntxiv, lub teeb liab liab, lub teeb ci tawm ntawm lub teeb ci (LED), lossis lwm lub teeb pom kev pom yog feem ntau txhaj rau hauv lub fiber, thiab cov khoom tso tawm tau saib xyuas thaum kawg ntawm lub fiber. Yog tias muaj kev tawg lossis lwm qhov cuam tshuam hauv cov hluav taws xob, lub zog kho qhov muag ntawm cov zis kawg ntawm cov fiber yuav raug txo los yog yuav tsis muaj lub teeb tawm txhua.
Tom qab lub teeb kis mus rau los ntawm cov hluav taws xob kho qhov muag, lub ntsej muag hluav taws xob kuj tseem tuaj yeem qhia ua qhov kev ua tiav ntawm kev ua haujlwm ntawm cov fiber ntau. Yog hais tias qhov kev saib xyuas ntawm lub fiber ntau loj dhau, lub kaw lus yuav tsis ua haujlwm zoo. Cov ntsuas hluav taws xob thiab cov khoom siv hluav taws xob yog cov khoom siv dav dav rau ntsuas qhov kis tau tus mob ntawm cov khoom hluav taws xob.
Lub ntsuas hluav taws xob fais fab yog lub photodiode uas hloov cov tswv yim mus rau hauv lub teeb ntsuas tau. Silicon photodiodes muaj kev nkag siab ntau nyob rau hauv thaj tsam ntawm 4OO txog rau 1000nm, thiab tsim nyog rau kev ntsuas ntawm cov khoom siv fiber ntau ntawm 650 thiab 850nm. Germanium (Ge) thiab indium yog arsenized ib leeg dhau ib ntawm. Cov pa luam yeeb (hauv GaAs) photodiodes tuaj yeem npog 800 txog 1600 nm, yog li lawv zoo tshaj plaws raws li photodetectors hauv 1300 nm lossis 1500 nm fiber ntau kho qhov muag. Lub ntes ntawm cov khoom siv germanium yog qhov pheej yig dua lub ntes ntawm indium-potassium arsenide hom, tab sis lub suab nrov yog loj dua. Yog tias cov paib ntsuas yuav ntsuas tau yog tsawg heev, koj yuav tsum siv cov tshuaj indium-potassium arsenide lossis cov chaw txias me me ntawm germanium detector. Hloov siab, yog tias lub teeb liab muaj zog, nws yuav tsum tau ua kom tsis txhob saib tau lub photodiode thiab tsim cov txiaj ntsig yuam kev.
Fiber ntau attenuation kuj yog ib qhov ntsuas uas peb ib txwm ntsuas. Lub ntsej muag ntawm qhov kho qhov muag fiber yog feem ntau yog los ntawm qhov txais tau thiab tawg ntawm qhov kho qhov muag fiber nws tus kheej, uas feem ntau yog qhia los ntawm attenuation coefficient α ntawm optical fiber, thiab chav tsev yog dB / km.
Attenuation coefficient ntawm ib hom fiber ntau yog feem ntau 0.5dB / km ntawm 1550nm, thaum qib-ntsuas cov iav fiber yog 1dB / km ntawm 1300nm thiab 3dB / km ntawm 850nm. Lub attenuation ntawm yas optical fiber ntau dua, txog 200dB / km ntawm 650nm. Txawm hais tias yas kho qhov muag hluav taws xob tau txais kev mloog tam sim no, cov kws txawj ntseeg tias vim muaj kev txwv ntawm txoj ntsiab lus poob ntawm cov yas optical fiber ntau, nws cov tswv yim ntev tsuas yog ob peb puas meters feem ntau.
Lub ntsej muag coefficient yuav tsum ntsuas ntawm ntau lub yoj yoj, yog li nws yog qhov zoo tshaj plaws los siv monochromator ua lub teeb ci, LED kuj tseem siv tau los ua qhov kev sim rau multimode fiber, thiab laser ua qhov khoom siv rau hom fiber ntau. Vim tias lub laser yuav tsim cov qauv hauv ib lub qauv hauv lub kis, ua rau ntsuas ntsuas tsis ntsuas.
Thaum xaiv qhov ntsuas teeb pom kev, nws yog qhov yuav tsum tau hloov kho nws cov spectrum thiab fiber txuas txuas ntawm cov yam ntxwv ntawm cov yam ntxwv ntawm cov khoom siv hluav taws xob uas siv rau hauv cov fiber ntau. Kev ua tiav ntawm cov roj carbon fiber ntau yog raws li qhov ua tau zoo thiab ntau yam ntawm cov khoom siv fiber ntau. Muaj ntau yam khoom siv kho qhov muag fiber ntau. Piv txwv, cov kho qhov muag hluav taws xob tau muab faib ua st adapters, sc adapters, fc adapters, thiab lc adapters.
OPTICO tus kws tshaj lij kev sib txuas lus pom zoo hais tias fiber ntau qhov muag tseem xav tau kev txhim kho ntau dua tam sim no, vim tias cov kab hluav taws xob lossis cov qauv hluav taws xob ntau yuav ua rau lub teeb nyob hauv qhov fiber ua rau sib cais. Yog li peb yuav tsum xaiv cov khoom lag luam txheem thaum nriav cov khoom fiber ntau. Muaj ntau OPTICO fiber ntau cov khoom lag luam xws li optical fiber jumpers, PLC splitters, optical FTTH teeb, DWDM, SFP, thiab lwm yam khoom lag luam lees txais cov khoom nruj nruj zoo hauv kev tsim khoom thiab tshuaj xyuas, xyuas kom zoo rau kev ua haujlwm zoo thiab cov khoom lag luam zoo, thiab kev nyab xeeb thiab kev ntseeg tau zoo kom ntseeg tau siv lub sijhawm ntev ntawm cov khoom.
