Mapitio

FUTV4443A 4 1 katika MUX-scrambling QAM moduleta ni utendaji ya juu na gharama nafuu ASI MUX-scrambling QAM kurekebisha kifaa karibuni iliyoundwa na FMUSER Company, ambayo kutoa 16 ASI pembejeo interface. Baada ya 4 njia multiplexing, scrambling na QAM kurekebisha mchakato, basi ni inatoa 4 RF pato (4 masafa karibu na bandari 1 RF). kifaa ni sifa kwa kiwango cha juu jumuishi, juu ya utendaji na gharama nafuu. Hii ni kurekebisha sana wapya kizazi mfumo CATV utangazaji.
