Dab tsi yog fiber ntau - tv optic ? Fiber ntau - tv optic siv cov kab nyias nyias ua los ntawm iav los yog yas kom xa cov ntaub ntawv ntawm pulses ntawm lub teeb. Qhov no technology muab fiber ntau - tv optic cov chaw muab kev pabcuam bandwidth xav tau los xa cov ntaub ntawv ntau, zoo meej rau kev xa cov channel suav, HD duab thiab cov teeb liab txhim khu kev qha.
Raws li, fiber ntau optic TV ua haujlwm li cas?
Fiber optic TV siv high-grade yas los yog iav xov hlau los xa cov pulses ntawm lub teeb uas yog ces decoded rau hauv cov ntaub ntawv thaum nws mus txog koj tv qhov twg raws li niaj zaus cable tv siv cov xov tooj tooj liab qhwv hauv aluminium ntawv xa hluav taws xob xaim hluav taws xob rau koj tv teem qhov twg nws yog decoded rau hauv
Tsis tas li ntawd, puas yog cable TV fiber ntau optic? Cable TV yog ib qho kev xa khoom tv programming rau cov neeg siv khoom ntawm xov tooj cua zaus (RF) cov cim xa los ntawm coaxial kab , los yog hauv cov tshuab tsis ntev los no, lub teeb pulses los ntawm fiber ntau - cov kab mob optic . Cov ntawv luv CATV feem ntau yog siv rau kab tv.
Tsis tas li ntawd, fiber ntau optic puas zoo dua li cable?
Fiber ntau optic Internet xa cov ntaub ntawv sai dua yooj yim kab . Nws tau xa mus rau ntawm kab mob siab rau, uas ua kom yooj yim dua nrawm dua dua kab . Nws tiv thaiv ntau yam mob uas kab Internet yog raug rau. Fiber ntau optic Internet tsis tshua muaj nqis thaum lub zog hluav taws xob.
Dab tsi yog fiber optic cable siv rau?
A fiber ntau optic cable yog lub network kab uas muaj cov iav iav fibers nyob rau hauv ib tug insulated casing. Lawv tau tsim los rau kev ua haujlwm ntev, kev ua haujlwm siab ntawm cov ntaub ntawv sib txuas, thiab kev sib txuas lus. Piv rau wired kab , fiber ntau optic cables muab bandwidth siab dua thiab xa cov ntaub ntawv hla mus ntev.
