GLB3500MT Terr TV ati Sat Fiber Optic Atagba
ọja Apejuwe
GLB3500M jẹ modular 45 ~ 2600MHz RF lori ọna asopọ okun, gbigbe awọn ikanni TV Terrestrial ati L-Band RF kan lori okun kan.
Satẹlaiti Broadcasting Taara (DBS) ati Taara si Ile (DTH) jẹ ọna olokiki julọ lati gbadun satẹlaiti TV ni agbaye. Lati ṣe, eriali satẹlaiti, okun coaxial, splitter tabi olona-switcher ati satẹlaiti olugba jẹ pataki. Sibẹsibẹ, fifi sori eriali satẹlaiti le nira si awọn alabapin ti ngbe ni awọn iyẹwu. SMTV (satẹlaiti mater eriali TV) jẹ ojutu ti o dara fun awọn eniyan ti ngbe ni ile tabi agbegbe lati pin satẹlaiti satẹlaiti kan ati eriali TV ori ilẹ. Pẹlu okun okun, SMTV RF ifihan agbara le wa ni jišẹ si 30Km jina tabi pin si 32 Irini taara, si 320 tabi 3200 tabi 32000 Irini nipasẹ GWA3530 fiber opitiki ampilifaya.
GLB3500M oriširiši GLB3500MT Atagba module ati GLB3500MR olugba module. Module atagba GLB3500MT ni ọkan tabi meji awọn ebute igbewọle RF nigba ti GLB3500MR ni ibudo iṣelọpọ RF kan. Pẹlu giga linearity 1550nm uncooled DFB laser, photodiode ati kekere ariwo RF ere Iṣakoso Circuit, GLB3500MT le fi ga didara Terrestrial TV awọn ikanni ati satẹlaiti RF lori okun si kan diẹ awọn alabapin taara tabi egbegberun FTTH awọn alabapin nipasẹ EDFA. Pẹlu 1310nm/1490nm/1550nm WDM aṣayan, GLB3500M le fi L-Band+TV RF sii lori GPON/GEPON. Lẹgbẹẹ ẹya modular, GLB3500M le ni ẹya 19”1RU lori ibeere. Okun si ẹya ile ṣiṣu ile ti GLB3500MR jẹ GFH2000 opitika LNB, nibiti alabapin FTTH kan nilo okun kan ninu ati ṣe awọn ifihan agbara satẹlaiti si awọn yara pupọ ninu ẹbi.
