GLB3500M-6 Six Wideband RF phezu kweFayibha
Ingcaciso yeMveliso
I-GLB3500M-6 yimodyuli ye-6ch CWDM yeSatellite RF ifayibha link, ithumela i-6ch wideband 174MHz ~ 2350MHz RF phezu kwefayibha enye ye-SM ukuya kwelinye okanye i-multi-optical receiver.I-CWDM nganye ye-optical wavelength ithwala i-174 ~ 2350MHz RF enye, exhasa i-Terrestrial TV 174 ~ 806MHz okanye i-950 ~ 2150MHz okanye indibaniselwano ye-Terr TV kunye ne-Sat RF, iqinisekisa umgangatho obalaseleyo we-RF kunye nokwahlula phakathi kweempawu ze-RF.
I-GLB3500M-6 yenzelwe ikakhulu izicelo ezimbini: ii-eriyali ezininzi zesathelayithi kwi-TV Headend kunye ne-SMATV.
Xa kuthelekiswa nesathelayithi RF phezu kwentambo yecoaxial ukuya kwi-TV Headend, i-GLB3500M-6 ineenzuzo ezintathu: 1. Ubuninzi be-eriyali yesathelayithi ezi-6 RFs ngaphezu kwe-SM fiber enye ukuya kwi-ofisi ye-Headend kunye nomgama omde kakhulu ukusuka kwi-100 yeemitha ukuya kwi-10Km;2. Ukukhuselwa kokukhanyisa kwizixhobo ze-Headhead ngenxa yentambo yefiber engaqhubekiyo;3. Ukwahlukaniswa komhlaba phakathi kweendawo zeSatellite dish kunye nendawo yesixhobo se-Headend.
I-SMATV (iSatellite Master Antenna TV) idume ngokunikezela ngeTV yesathelayithi kunye neTV yasemhlabeni kubabhalisi abahlala kumagumbi okanye kuluntu.I-SMATV yesiNtu inokusasaza imixholo ye-eriyali eyinkosi ngokutshintshela kwisathelayithi yabamkeli ngentambo eyicoaxial.Ngenxa yelahleko ephezulu kwi-IF frequency yesathelayithi, umgama wentambo ye-SMATV ungaphantsi kwe-150 yeemitha kunye ne-IF yeamplifier ye-intanethi.I-GLB3500M-6 yenza ukuba i-SMATV ibe ngaphezu kwefayibha kwizakhiwo ezininzi kunye nababhalisi kumgama we-fiber radius 5Km.Kunye ne-PLC i-fiber splitter kunye ne-cascading multiswitch kwisakhiwo ngasinye, i-GLB3500M-6 inokusasaza ii-antenna ezininzi ze-satellite RFs kunye ne-Terr TV kwinani lababhalisi kuluntu.
I-GLB3500M-6 i-fiber link iquka i-GLB3500M-6T i-optical transmitter kunye ne-GLB3500M-6R i-optical receiver.Nge-CWDM lasers/photodiode kunye nesandi esiphantsi se-RF yokulawula ukufumana isiphaluka, enye i-GLB3500M-6T inokuhambisa umgangatho ophezulu we-RF ukuya kuma-32 GLB3500M-6R abamkeli be-optical.
