Lub analog optical transceiver yog ib hom ntawm optical transceiver, uas feem ntau yog siv cov analog zaus hloov kho, amplitude modulation, thiab theem kev hloov kho los hloov cov yeeb yaj kiab baseband, suab, cov ntaub ntawv thiab lwm yam teeb liab ntawm qee qhov chaw thauj khoom zaus, thiab xa nws los ntawm kev xa xov hluav taws xob optical transceiver. .Hloov kho qhov muag teeb liab: Cov teeb liab kho qhov muag tawm los ntawm analog optical transceiver yog ib qho analog optical modulation teeb liab, uas hloov lub amplitude, zaus, thiab theem ntawm cov teeb liab kho qhov muag nrog lub amplitude, zaus, thiab theem ntawm input analog carrier teeb liab.Yog li, dab tsi yog qhov analog optical transceiver?Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm analog optical transceivers?Thov ua rawsJHA TECHmus kawm txog analog optical transceiver.
Lub analog optical transceiver siv PFM kev hloov kho thev naus laus zis los xa cov duab teeb liab hauv lub sijhawm.Qhov kawg xa tawm ua PFM kev hloov pauv ntawm cov teeb liab analog video, thiab tom qab ntawd ua hluav taws xob hloov kho qhov muag.Tom qab cov teeb liab kho qhov muag tau xa mus rau qhov kawg tau txais, nws ua haujlwm photoelectric hloov dua siab tshiab, thiab tom qab ntawd ua PFM demodulation kom rov qab tau cov teeb liab video.Vim yog siv PFM kev hloov kho thev naus laus zis, nws qhov kis tau tus mob tuaj yeem ncav cuag 50Km lossis ntau dua.Los ntawm kev siv wavelength division multiplexing thev naus laus zis, ob txoj kev sib kis ntawm cov duab thiab cov ntaub ntawv teeb liab kuj tuaj yeem ua tiav ntawm ib qho kev kho qhov muag fiber ntau kom tau raws li qhov xav tau ntawm kev saib xyuas cov haujlwm.
Disadvantages ntawm analog optical transceiver:
a) Kev debugging ntau lawm yog qhov nyuaj dua;
b) Nws yog ib qho nyuaj rau ib qho kev kho qhov muag fiber ntau kom paub txog ntau cov duab xa mus, thiab kev ua haujlwm yuav raug txo.Qhov no analog optical transceiver feem ntau tsuas yog kis tau 4 raws ntawm cov duab ntawm ib qho fiber ntau optical;
c) Tsis muaj peev xwm tiv thaiv kev cuam tshuam tsis zoo, cuam tshuam los ntawm ib puag ncig yam, thiab kub drift;
d) Vim hais tias cov qauv analog thiab demodulation tshuab tau txais kev pom zoo, nws qhov kev ruaj ntseg tsis siab txaus.Raws li lub sij hawm siv nce los yog cov yam ntxwv ib puag ncig hloov, kev ua tau zoo ntawm optical transceiver kuj yuav hloov, uas yuav ua rau qee qhov tsis yooj yim rau kev siv engineering.
