GLB3500M-4 Terr TV le One Quattro LNB holim'a fiber
Tlhaloso ea Sehlahisoa
GLB3500E-4R satellite TV FTTH Optical LNB ke seamoheli sa fiber optic se nang le likarolo tse peli, se fetolang li-RF tse nne tse pharaletseng ho tsoa ho lisathelaete tse peli (mohlala, Nilesat le Arabsat) holim'a matšoao a faeba hore e be tlhahiso e le 'ngoe ea RF bakeng sa li-satellite tse 4 tse amohelang lehae le le leng.Ho sebetsa le 2pcs Greatway GLB3500E-2T satellite TV optical transmitters ho tsoa ho li-fiber tse peli, GLB3500E-4R e hahile mochini oa SatCR o fetolang RF e pharaletseng ho tloha ho lisathelaete tse peli, e hlahisa lihlopha tse 4 tsa basebelisi ba sathelaete boema-kepeng bo le bong ba SatCR RF bakeng sa li-satellite tse 4 tse amohelang li-satellite.
SMATV (Satellite Master Antenna TV) e tumme ho fana ka TV ea sathelaete le TV ea lefatše ho ba ngolisitseng ba lulang lifoleteng kapa sechabeng.Traditional SMATV e ka tsamaisa litaba tsa antenna tse kholo ka li-multiswitch ho li-satellite tse amohelang ka thapo ea coaxial.Ka lebaka la tahlehelo e phahameng ea maqhubu a holimo a sathelaete, sebaka sa cable sa SMATV se ka tlase ho limithara tse 150 leha e le ka amplifier ea inthaneteng ea IF.Lisathelaete tse peli tse tloaelehileng Sisteme ea SMATV e hloka likhoele tse 9 tsa RF ho tloha marulelong a moaho ho ea ho li-multiswitch tse ngata, tse sebeletsang ba ngolisitseng ba ka tlase ho 100 mohahong o le mong.Bakeng sa li-satellite tse peli SMATV holim'a fiber, Greatway Technology e na le GLB3500M-8 e le tharollo ea FTTB le GLB3500E-4R e le tharollo ea FTTH.Tharollo ea FTTB e lokela ho ba le STB e tloaelehileng ea sathelaete, ha tharollo ea FTTH e tlameha ho ba le satellite STB e tšehetsang unicable.
GLB3500E-4R e na le boema-kepe ba khetho ea 1310nm/1490nm/1550nm WDM bakeng sa ho sebelisana 'moho le GPON ONU ts'ebelisong efe kapa efe ea FTTH, e lumellang hore litaba tse felletseng tsa sathelaete LNB li kenngoe tsamaisong ea GPON.
Likarolo tse ling:
•Ntlo ea polasetiki e tiileng.
•Lisebelisoa tse peli tsa fiber ea SC/APC le tlhahiso e le 'ngoe ea RF.
•High Linearity Photodiode.
•Sebaka sa mahlo sa AGC: -6dBm ~ +1dBm.
•Boema-kepe bo le bong ba SatCR RF bakeng sa ba amohelang batho ba 4 ba sa sebetseng hantle.
•Sat RF Band: 950 ~ 2150MHz.
•Terene ea Lefatše ea RF Bandwidth: 88~250MHz.
•E lumellana le litekanyetso tsa EN50494 + EN50607.
•Boikhethelo boema-kepe ba WDM ho ea GPON ONU.
•Khetho: Boema-kepe bo le bong ba SatCR RF bakeng sa ba amohelang batho ba ka bang 8 ba sa sebetseng hantle.
