I-GLB3500M-16 Terr TV kunye ne-Four Quattro LNBs phezu kwefiber
Ingcaciso yeMveliso
I-GLB3500M-16 yi-16ch CWDM Satellite RF fiber link, ihambisa i-16 IFs ukusuka kwi-4 Quattro LNBs kwiiDishi zeSatellite ezi-4 kunye ne-1 ye-terrestrial TV RF ngaphezu kwe-SM fiber enye kubabhalisi abaninzi. Ubude bokukhanya be-CWDM nganye buphethe i-950 ~ 2150MHz isignali ye-RF (okanye i-174 ~ 2150MHz, kuquka i-Terrestrial TV), iqinisekisa ukusebenza kwe-RF okugqwesileyo kunye nokuhlukaniswa phakathi kwe-satellite polarities.
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-frequency ephezulu yesathelayithi, umgama wentambo ye-SMATV ungaphantsi kwe-150 yeemitha kunye ne-IF yeamplifier ye-intanethi. Inkqubo ye-SMATV ezine ye-Quattro LNB idinga iintambo ze-RF ezili-17 ukusuka kuphahla lwesakhiwo ukuya kwi-cascading multiswitch, ekhonza ababhalisile abangaphantsi kwe-100 kwisakhiwo esinye. I-GLB3500M-16 yenza ukuba i-SMATV ibe ngaphezu kwefayibha kwizakhiwo ezininzi kunye nababhalisi. Kanye kunye ne-PLC i-fiber splitter kunye ne-cascading multiswitch kwisakhiwo ngasinye, i-GLB3500M-16 inokusasaza i-Quattro LNB ezine kunye ne-Terr TV ukuya kubabhalisi be-3200 abaninzi kuluntu. Esi sisicelo esiqhelekileyo se-hybrid fiber coaxial cable kwiTV yesathelayithi.
I-GLB3500M-16 i-fiber link iquka i-GLB3500M-16T i-fiber optic transmitter kunye ne-GLB3500M-16R i-fiber optic receiver. Nge-CWDM lasers/photodiode kunye nesandi esiphantsi se-RF yokulawula ukufumana isiphaluka, enye i-GLB3500M-16T inokuhambisa umgangatho ophezulu we-RF ukuya kwi-32pcs ephezulu ye-GLB3500M-16R yabamkeli be-optical ngaphakathi kwe-5Km umgama wefayibha.
Ezinye iimpawu:
• IAluminiyam Izindlu zentsimbi ezinesinki yobushushu.
• Akukho uyilo lwabalandeli.
• 16 wahlala polarity broadband RF 950 ~ 2150MHz.
• One Terrestrial TV RF 174~806MHz.
• Ingxolo ephantsi ye-RF Gain Control circuit.
