Ib qho fiber ntau optical yog ib txoj kab txuas rau xa cov teeb liab kho qhov muag.
Peb hu cov tsis xav tau hluav taws xob teeb liab nyob rau hauv lub channel "suab nrov Lub suab nrov nyob rau hauv kev sib txuas lus system yog superimposed rau lub teeb liab.Thaum tsis muaj cov teeb liab kis tau tus mob, kuj tseem muaj suab nrov hauv kev sib txuas lus.“Lub suab nrovib txwm muaj nyob hauv kev sib txuas lus.Lub suab nrov tuaj yeem suav tau tias yog ib hom kev cuam tshuam hauv cov channel, tseem hu ua kev cuam tshuam ntxiv vim nws yog superimposed ntawm lub teeb liab.Suab nrov yog teeb meem rau cov teeb liab kis tau tus mob.Nws tuaj yeem cuam tshuam cov teeb liab analog, cuam tshuam cov teeb liab digital, thiab qeeb tus nqi ntawm cov ntaub ntawv tuaj yeem xa mus.
Raws li covqhov kev faib tawm, suab nrov tuaj yeem muab faib uaob pawg: neeg tsim suab nrov thiab ntuj nrov nrov.Cov suab nrov yog tsim los ntawm tib neeg kev ua ub no, xws li hluav taws xob hluav taws xob tshwm sim los ntawm kev xyaum hluav taws xob thiab hluav taws xob hloov pauv, hluav taws xob hluav taws xob tsim los ntawm lub tshuab hluav taws xob tsheb, cuam tshuam los ntawm cov teeb fluorescent, thiab hluav taws xob hluav taws xob hluav taws xob tsim los ntawm lwm lub xov tooj cua thiab cov khoom siv hauv tsev.Lub suab nrov ntuj yog ntau yam ntawm cov hluav taws xob hluav taws xob hluav taws xob hauv qhov xwm txheej, xws li xob laim, suab nrov atmospheric, thiab cosmic suab nrov los ntawm lub hnub thiab lub galaxy Tsis tas li ntawd, muaj lub suab nrov tseem ceeb heev, uas yog lub suab nrov thermal Thermal suab nrov los ntawm thermal suab. ntawm electrons nyob rau hauv tag nrho cov resistive Cheebtsam.Piv txwv li, cov xov hlau, cov khoom siv hluav taws xob, thiab cov khoom siv semiconductor txhua tus tsim cov suab nrov thermal.
Yog li ntawd, lub suab nrov thermal yog ubiquitous thiab inevitably muaj nyob rau hauv tag nrho cov khoom siv hluav taws xob tshwj tsis yog cov khoom siv nyob rau hauvthermodynamic kubntawm OK Nyob rau hauv resistive Cheebtsam, dawb electrons yog tas li txav los ntawm thermal zog thiab randomly tsiv nyob rau hauv ib tug tawg kab txoj kev vim kev sib tsoo nrog lwm yam hais nyob rau hauv cov lus tsa suab, piv txwv li, Brownian motion Nyob rau hauv tsis muaj lwm yam quab yuam, qhov nruab nrab tus nqi ntawm cov tam sim no generated. los ntawm Brownian motion ntawm cov electrons yog sib npaug zos rau xoom, tab sis ib qho AC tivthaiv yuav raug generated.Cov khoom siv AC no hu ua thermal nrov.Thermal suab nrov muaj ntau ntau zaus, los ntawm 0 Hz mus rau 102 Hz, thiab lawv tag nrho cov sib npaug.
Nov yog tsab xov xwm "lub suab nrov hauv channel" uas tau coj los rau koj los ntawm Shenzhen HDV phoelectron Technology Co., Ltd. vam tias tsab xov xwm no tuaj yeem pab koj kom koj paub ntau ntxiv.Dhau li ntawm tsab xov xwm no yog tias koj tab tom nrhiav rau lub tuam txhab kev sib txuas lus zoo fiber ntau cov khoom lag luam koj tuaj yeem xav txogtxog peb.
Shenzhen HDV phoelectron Technology Co., Ltd., Ltd. yog cov chaw tsim khoom ntawm cov khoom sib txuas lus.Tam sim no, cov cuab yeej tsim tawm npog lubONU series, Optical module series, OLT series, thiabtransceiver series.Peb tuaj yeem muab cov kev pabcuam customized rau cov xwm txheej sib txawv.Zoo siab txais tossab laj.
