I-GLB3500M-8 Terr TV kunye ne-Two Quattro LNBs phezu kwefiber
Ingcaciso yeMveliso
GLB3500M-8yi8ch CWDM Satellite RF ikhonkco ifayibha, ukuthumela8IFs ukusuka2Quattro LNBs kwi2Izitya zeSatellite ezahlukeneyo kunye ne-1 yeTV ye-terrestrial RF ngaphezulu kwefayibha enye ye-SM 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. Iinkqubo ezimbini ze-Quattro LNB SMATV zifuna iintambo ze-RF ezisi-9 ukusuka kuphahla lwesakhiwo ukuya kwi-cascading multiswitch, ekhonza ababhalisile abangaphantsi kwe-100 kwisakhiwo esinye. I-GLB3500M-8 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-8 inokuhambisa ii-Quattro LNB ezimbini kunye ne-Terr TV ukuya kubabhalisi be-3200 abaninzi kuluntu. Esi sisicelo esiqhelekileyo se-hybrid fiber coaxial cable kwiTV yesathelayithi.
I-GLB3500M-8 i-fiber link iquka i-GLB3500M-8T i-fiber optic transmitter kunye ne-GLB3500M-8R i-fiber optic receiver. Nge-CWDM lasers/photodiode kunye nengxolo ephantsi ye-RF yokulawula ukufumana isekethe, enye i-GLB3500M-8T inokuhambisa umgangatho ophezulu weRF ukuya kwi-32pcs ephezulu ye-GLB3500M-8R yabamkeli be-optical ngaphakathi kwe-5Km umgama wefayibha.
Ezinye iimpawu:
• IAluminiyam Izindlu zentsimbi ezinesinki yobushushu.
• Akukho uyilo lwabalandeli.
• 8 wahlala polarity broadband RF 950 ~ 2150MHz.
• One Terrestrial TV RF 174~806MHz.
• High Linearity Photodiode.
• Ingxolo ephantsi ye-RF Gain Control circuit.
