GLB3500M-6 Lix Wideband RF oo ka sarreeya Fiber
Sharaxaada Alaabta
GLB3500M-6 waa qaab-dhismeedka 6ch CWDM Satellite RF fiber isku xirka, gudbinta 6ch wideband 174MHz ~ 2350MHz RF in ka badan hal fiber SM hal ama kuwa badan oo qaata qalabka. Mid kasta oo ka mid ah hirarka indhaha ee CWDM wuxuu qaadaa hal 174 ~ 2350MHz RF, isagoo taageeraya Terrestrial TV 174 ~ 806MHz ama 950 ~ 2150MHz ama isku dhafka Terr TV iyo Sat RF, isagoo hubinaya tayada calaamadda RF ee heer sare ah iyo go'doominta wadajirka ah ee calaamadaha RF.
GLB3500M-6 waxaa inta badan loogu talagalay laba codsi: anteenooyinka satalaytka badan ilaa TV Headend iyo SMTV.
Marka la barbar dhigo dayax-gacmeedka RF ee ka sarreeya cable-ka coaxial ilaa TV Headend, GLB3500M-6 waxay leedahay saddex faa'iidooyin: 1. Ugu badnaan 6 anteenada dayax-gacmeedka RFs oo ka badan hal fiber SM ilaa xafiiska Headend iyo masaafo aad u dheer oo u dhaxaysa 100 mitir ilaa 10Km; 2. Ilaalinta iftiinka qalabka Headead sababtoo ah fiilada fiber-ka ee aan shaqaynayn; 3. Go'doomin dhexmara goobaha saxanka ee Satellite-ka iyo goobta qalabka Headend.
SMTV (Satellite Master Antenna TV) ayaa caan ku ah in uu bixiyo TV-ga satalaytka iyo TV-ga dhulka ee 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. Sababo la xiriira luminta sare ee dayax gacmeedka IF inta jeer, masaafada fiilada SMTV waa in ka yar 150 mitir xitaa haddii cod-weyneeye online ah. GLB3500M-6 waxay awood u siinaysaa SMTV in ka badan fiber dhismayaal iyo macaamiil badan oo ku jira masaafo 5Km radius fiber. Si wada jir ah PLC fibre splitter iyo cascading multiswitchs ee dhismo kasta, GLB3500M-6 waxay u qaybin kartaa multi-satalayt anteenada RFs iyo Terr TV tiro macaamiisha ah ee bulshada.
GLB3500M-6 fiber isku xirka waxaa ka mid ah GLB3500M-6T gudbiyaha indhaha iyo GLB3500M-6R aqbalaha indhaha. Iyada oo leysarka CWDM/photodiode iyo sanqadha hoose ee RF kontoroolka kontoroolka, hal GLB3500M-6T ayaa keeni kara RF tayo sare leh ilaa ugu badnaan 32 GLB3500M-6R aqbaleyaasha indhaha.
