GLB3500M-6 Six Wideband RF lori Fiber
ọja Apejuwe
GLB3500M-6 jẹ modular 6ch CWDM Satellite RF ọna asopọ okun, gbigbe 6ch wideband 174MHz ~ 2350MHz RF lori okun SM kan si ọkan tabi awọn olugba opiti pupọ. Kọọkan CWDM opitika wefulenti gbejade ọkan 174 ~ 2350MHz RF, atilẹyin Terrestrial TV 174 ~ 806MHz tabi 950 ~ 2150MHz tabi awọn apapo ti Terr TV ati Sat RF, aridaju o tayọ ifihan agbara RF ati ipinya laarin awọn ifihan agbara RF.
GLB3500M-6 jẹ apẹrẹ fun awọn ohun elo meji: awọn eriali satẹlaiti pupọ si TV Headend ati SMTV.
Akawe pẹlu satẹlaiti RF lori okun coaxial si TV Headend, GLB3500M-6 ni o ni meta anfani: 1. O pọju 6 satẹlaiti eriali RFs lori ọkan SM okun si awọn Headend ọfiisi ati Elo gun ijinna lati 100 mita to 10Km; 2. Idaabobo ina si awọn ohun elo Headead nitori okun okun ti kii ṣe itọnisọna; 3. Ipinya ilẹ laarin awọn ipo satelaiti Satẹlaiti ati ipo ohun elo Headend.
SMTV (Satẹlaiti Titunto Antenna TV) jẹ olokiki lati pese TV satẹlaiti ati TV ori ilẹ si awọn alabapin ti ngbe ni awọn iyẹwu tabi agbegbe. SMTV ti aṣa le pin kaakiri awọn akoonu eriali titunto si nipasẹ multiswitch si awọn olugba satẹlaiti lori okun coaxial. Nitori pipadanu ti o ga julọ ni satẹlaiti giga IF igbohunsafẹfẹ, ijinna okun SMTV kere ju mita 150 paapaa pẹlu IF online ampilifaya. GLB3500M-6 ngbanilaaye SMTV lori okun si awọn ile diẹ sii ati awọn alabapin ni ijinna okun rediosi 5Km. Paapọ pẹlu PLC fiber splitter ati cascading multiswitchs ni kọọkan ile, GLB3500M-6 le pin ọpọ satẹlaiti eriali RFs ati Terr TV si awọn nọmba kan ti awọn alabapin ni awujo.
GLB3500M-6 okun ọna asopọ pẹlu GLB3500M-6T opitika Atagba ati GLB3500M-6R opitika olugba. Pẹlu CWDM lasers / photodiode ati ariwo kekere RF ere iṣakoso Circuit, ọkan GLB3500M-6T le fi RF didara ga si awọn olugba opiti 32 GLB3500M-6R ti o pọju.
