Raws li cov zis teeb liab hom, kev sib cais transmitters tau tuaj yeem faib ua analog offetter lawb rho tawm transmitters thiab cov zis digital tso rho tawm. Cov qub feem ntau raug xa mus ua ib qho kev rho tawm, thaum lub tom kawg yog feem ntau yog xa mus ua cov khoom siv digital.
Cov paib digital muaj cov anti {- kev cuam tshuam nrog cov peev xwm digital, thiab ntev li qhov kev ua yuam kev, yuav tsis muaj kev ua yuam kev lossis kev ua raws li lub sijhawm thaum lub sijhawm xa rov qab. Cov cim qhia digital tau kis los ntawm cov roj fiber ntau, ua kom muaj ntau yam cuam tshuam hluav taws xob. Kev Fiber Optical tseem muab cov hluav taws xob sib cais, ua cov digital transmitters haum rau ntau yam ntawm lub zog hluav taws xob ib puag ncig.
