GWE1000 CATV MDU amplifier yo mu nzu
Ibisobanuro ku bicuruzwa
GWE1000 nigiciro cyinshi cyamazu yo guturamo yagenewe inzira yiminsi ibiri yimbere CATV na Docsis 3.1 cyangwa Docsis 3.0 cyangwa Modem ya kabili ya modem ya Docsis 2.0. Usibye gutangaza televiziyo yo mu rwego rwo hejuru cyangwa TV ya DVB-C, GWE1000 yujuje ibyifuzo byuyu munsi wagura imiyoboro yagutse yagutse ishingiye kuri CMTS hamwe n’ikoranabuhanga rya modem. Inzira igana imbere RF ifite 37dB yunguka igera kuri 48dBmV RF isohoka mugihe inzira yo kugaruka ifite 27dB yunguka igera kuri 44dBmV inzira yo kugaruka kurwego rwa RF. Yashizweho kugirango ushyireho imiyoboro ya HFC mumazu yamagorofa, iyi yunguka cyane yo gukwirakwiza imbere mu nzu iraboneka hamwe numuyoboro mugari wa 1003MHz (1218MHz ubishaka) kugirango imikorere ya sisitemu inoze. Usibye ibice 42 / 54MHz byibanze bigabanijwe, GWE1000 irashobora gutanga 85 / 102MHz cyangwa 204 / 258MHz inshuro zigabanijwe kubisabwa mugukwirakwiza umurongo mugari.
Igisohoka kimwe cyongera imbaraga kiranga ibintu bihoraho bishobora guhindurwa hamwe no guhora bihinduranya kuringaniza inzira zombi zerekeza imbere no kugaruka inzira ya RF inzira kugirango ihindurwe cyane mugushiraho amplifier. Igice kirimo F-isanzwe yinjiza nibisohoka bihuza ibyambu, -20dB inzira yimbere na -20dB yo kugaruka inzira yo kugerageza. Kugirango uhuze ibyifuzo bitandukanye mubisabwa gutura, ibyambu byose bya RF bya GWE1000 byateguwe kugirango birinde 6KV kurinda.
GWE1000 ikoresha ingufu zitarenze 14W. Moderi zose za amplifier zashyizwe kumurongo umwe wa aluminium. GWE1000 ifite impapuro z'icyuma zubatswe hamwe na silike ikora.
MDU igaragaramo amashanyarazi yo guhinduranya amashanyarazi, ashobora kwakira voltage yinjira kuva 90 kugeza 240V kuri frequence ya 50 cyangwa 60 Hz nta guhinduka.
Ibindi biranga:
• Duplexer yo gutandukana kwinshi.
• 90 ~ 240V AC yinjiza amashanyarazi.
• -20dB amanota yikizamini imbere no kugaruka inzira.
