GLB3500E-4R Nilesat iyo Arabsat oo ka badan laba fibre ilaa hal guri
Sharaxaada Alaabta
GLB3500E-4R satellite TV FTTH Optical LNB waa laba-core fiber input optic receiver, oo u beddelaya afar RF-ballaaran oo ka yimid laba satalayt (tusaale, Nilesat iyo Arabsat) kor u qaadista calaamadaha fiber-ka ee hal wax soo saar oo RF ah ilaa 4 satalaytka qaata hal guri.Iyada oo la shaqaynaysa 2pcs Greatway GLB3500E-2T satellite TV-ga gudbinta indhaha ee laba fiber-ka ah, GLB3500E-4R waxay ku dhex dhisantay moduleka SatCR oo ka beddelaya RF ballaaran oo ka yimid laba satalayt, waxay soo saartaa 4 satalaytka isticmaalaha hal deked SatCR RF oo loogu talagalay 4 qaata satalaytka aan awoodin.
SMTV (Satellite Master Antenna TV) ayaa caan ku ah in uu bixiyo TV satalaytka iyo TV-ga dhulka macaamiisha macaamiisha ku nool guryaha ama bulshada.SMTV-dhaqameedku waxa uu u qaybin karaa waxa ku jira anteenada sayidkiisa iyada oo loo sii marayo multiswitch-ka qaata satalaytka ee koraya fiilada coaxial.Khasaaraha sarreeya ee soo noqnoqda dayax-gacmeedka oo sarreeya awgeed, masaafada fiilada SMTV waa in ka yar 150 mitir xitaa haddii cod-weyneeye khadka ah.Caadi ahaan labada satalayt ee nidaamka SMTV wuxuu u baahan yahay 9 fiilooyin RF ah oo ka soo baxaya saqafka sare ee dhismaha ilaa saqafyada badan ee cascading, oo u adeegaya in ka yar 100 macaamiil ah hal dhisme.Laba dayax-gacmeed oo SMTV ah oo ka sarreeya fiber, Tiknoolajiyada Greatway waxay leedahay GLB3500M-8 oo ah xalka FTTB iyo GLB3500E-4R oo ah xalka FTTH.Xalka FTTB waa inuu lahaadaa satalaytka caadiga ah ee STB, halka xalka FTTH uu leeyahay satalaytka STB oo taageeraya mid aan la awoodin.
GLB3500E-4R waxay haysataa 1310nm/1490nm/1550nm WDM doorasho deked ah oo la shaqaynaysa GPON ONU codsi kasta oo FTTH ah, kaas oo awood u siinaya satalaytka buuxa ee LNB in la geliyo nidaamka GPON.
