Transceiver-ka analooga ah waa nooc ka mid ah transceiver indhaha, kaas oo inta badan qaata isbedbeddelka soo noqnoqda analoogga, habaynta baaxadda, iyo habaynta wejiga si loo beddelo fiidiyoowga saldhigga ah, maqalka, xogta iyo calaamadaha kale ee soo noqnoqoshada side qaarkood, oo ku gudbiya gudbinta gudbinta indhaha. .Calaamadaha indhaha ee la kala qaado: Calaamadda indhaha ee uu soo saaro transceiver-ka analoogga waa calaamadda wax-ka-beddelka indhaha ee analooga ah, taas oo beddeleysa baaxadda, soo noqnoqoshada, iyo wejiga ishaarka indhaha oo leh baaxadda, soo noqnoqoshada, iyo wejiga calaamadda gudbinta analoogga.Haddaba, waa maxay transceiver indhaha analoogga ah?Waa maxay faa'iidooyinka iyo khasaaraha ka mid ah transceivers analoogga ah?Fadlan lasocoJHA TECHsi aad wax uga barato transceiver-ka analoogga ah.
Transceiver-ka analoogga ah wuxuu isticmaalaa tignoolajiyada habaynta PFM si uu u gudbiyo calaamadaha sawirka wakhtiga dhabta ah.Dhammaadka gudbinta waxa ay qabataa qaabaynta PFM ee calaamada fiidyowga analoogga ah, ka dibna waxa ay qabataa beddelka korantada-optical.Ka dib markii calaamadda indhaha loo gudbiyo dhamaadka helitaanka, waxay qabataa beddelka sawir-qaadista, ka dibna waxay qabataa PFM demodulation si ay u soo kabsato calaamadda muuqaalka.Isticmaalka tignoolajiyada is-beddelka PFM awgeed, masaafada gudbinteeda waxay gaari kartaa 50Km ama ka badan.Iyada oo la adeegsanayo tignoolajiyada isku-dhufashada mawjada dhererka, gudbinta laba-geesoodka ah ee sawirka iyo calaamadaha xogta ayaa sidoo kale lagu xaqiijin karaa hal fiber indhaha si loo daboolo baahiyaha dhabta ah ee mashaariicda kormeerka.
Faa'iido darrada transceiver-ka analoogga ah:
a) Qalabaynta wax-soo-saarka ayaa aad u dhib badan;
b) Way adag tahay in hal fiber indhaha ah si loo xaqiijiyo gudbinta sawirka kanaalka badan, waxqabadkana waa la dhimi doonaa.Noocan ah transceiver indhaha analoogga guud ahaan kaliya gudbin kara 4 channels of images on hal fiber indhaha;
c) Awood liidata ka-hortagga faragelinta, oo ay si weyn u saameeyeen arrimaha deegaanka, iyo qulqulka heerkulka;
d) Sababtoo ah is-beddelka analoogga iyo tignoolajiyada demodulation waa la qaatay, xasilloonideedu maaha mid aad u sareysa.Marka wakhtiga la isticmaalo uu kordho ama dabeecadaha deegaanku is beddelaan, waxqabadka muraayadaha indhaha ayaa sidoo kale isbeddeli doona, taas oo u keeni doonta xoogaa dhib ah isticmaalka injineernimada.
