Yuav ua li cas kuaj fiber ntau optic transceivers?

Nrog rau txoj kev loj hlob ntawm lub network thiab kev nce qib ntawm cov cuab yeej technology, ntau fiber optic tivthaiv manufacturers tau tshwm sim nyob rau hauv kev ua lag luam, sim mus txeeb ib feem ntawm lub ntiaj teb no network.Txij li cov tuam txhab tsim khoom lag luam tsim ntau yam khoom, lawv lub hom phiaj yog ua kom cov khoom zoo thiab sib koom ua ke kom cov neeg siv khoom tuaj yeem sib xyaw ntau yam ntawm cov tuam txhab sib txawv.Qhov no feem ntau yog vim muaj kev txhawj xeeb txog nyiaj txiag, vim tias ntau lub chaw cov ntaub ntawv yeej ib txwm nrhiav kev daws teeb meem zoo los siv hauv lawv cov tes hauj lwm.

Optical transceiversyog ib feem tseem ceeb ntawm fiber optic networks.Lawv hloov dua siab tshiab thiab tsav lub fiber optic cable los ntawm nws.Lawv muaj ob qhov tseem ceeb: transmitter thiab receiver.Thaum nws los txog rau kev saib xyuas thiab kev daws teeb meem, nws yog ib qho tseem ceeb uas yuav tsum muaj peev xwm twv tau, sim, thiab tshawb pom qhov twg muaj teeb meem tuaj yeem tshwm sim.Qee zaum, yog tias qhov kev sib txuas tsis tau raws li qhov xav tau me ntsis yuam kev, peb tsis tuaj yeem qhia thaum xub thawj siab ib muag uas qhov kev sib txuas ua rau muaj teeb meem.Nws tuaj yeem yog cable, transceiver, receiver lossis ob qho tib si.Feem ntau, cov lus qhia tshwj xeeb yuav tsum tau lees paub tias txhua tus txais yuav ua haujlwm zoo nrog txhua tus neeg xa xov xwm phem tshaj plaws, thiab lwm yam, txhua lub transmitter yuav muab lub teeb liab ntawm qhov zoo txaus kom tau txais los ntawm txhua tus neeg txais qhov phem tshaj plaws.Cov txheej txheem phem tshaj plaws feem ntau yog qhov nyuaj tshaj plaws los txhais.Txawm li cas los xij, feem ntau muaj plaub kauj ruam los ntsuas qhov transmitter thiab receiver qhov chaw ntawm lub transceiver.

Fiber Optic Transceiver Modules

Thaum kuaj cov ntu transmitter, kev sim suav nrog kev ntsuas lub wavelength thiab cov duab ntawm cov teeb liab tso zis.Muaj ob txoj hauv kev los ntsuas lub transmitter:

Lub teeb tso zis ntawm lub transmitter yuav tsum tau sim nrog kev pab los ntawm ob peb lub teeb pom kev zoo metrics, xws li daim npog qhov ncauj, optical modulation amplitude (OMA), thiab extinction ratio.Kev sim siv qhov muag daim duab daim npog qhov muag kuaj, ib txoj hauv kev los saib cov transmitter waveforms thiab muab cov ntaub ntawv hais txog tag nrho cov transmitter kev ua tau zoo.Hauv daim duab qhia qhov muag, txhua qhov kev sib txuas ntawm cov ntaub ntawv cov qauv yog superimposed rau ib leeg ntawm ib lub sij hawm axis, feem ntau tsawg dua ob lub sij hawm dav.Qhov kev xeem tau txais ib feem yog qhov nyuaj ntawm cov txheej txheem, tab sis kuj tseem muaj ob theem kev xeem:

Thawj feem ntawm qhov kev xeem yog kom paub meej tias tus neeg txais tuaj yeem khaws cov teeb liab tsis zoo thiab hloov nws.Qhov no yog ua los ntawm kev xa cov teeb tsis zoo rau lub receiver.Txij li qhov no yog lub teeb liab kho qhov muag, nws yuav tsum tau calibrated siv jitter thiab optical zog ntsuas.Lwm qhov ntawm qhov ntsuas yog ntsuas cov hluav taws xob nkag mus rau lub receiver.Nyob rau hauv cov kauj ruam no, peb hom kev ntsuam xyuas yuav tsum tau ua: kev ntsuam xyuas lub ntsej muag lub ntsej muag kom paub meej lub qhov muag loj txaus, jitter ntsuam xyuas los ntsuam xyuas tej yam ntawm jitter npaum li cas thiab jitter kam rau ua, thiab kev ntsuam xyuas ntawm lub receiver lub peev xwm los taug qab jitter nyob rau hauv nws nyob rau hauv lub lub voj bandwidth.
