IINKCUKACHA ZEMVELISO

Ingcaciso yeMveliso

I-TV yesathelayithi ye-GLB3500E-4R ye-FTTH i-Optical LNB yi-fiber engundoqo-ezimbini i-fiber input optic receiver, iguqula ii-RF ezine ezibanzi ukusuka kwiisathelayithi ezimbini (umzekelo, i-Nilesat ne-Arabsat) phezu kwemiqondiso yefayibha ibe yimveliso yeRF enye ukuya kuthi ga kwisathelayithi e-4 yabamkeli kwikhaya elinye. Ukusebenza kunye ne-2pcs Greatway GLB3500E-2T ye-satellite TV optical transmitter ukusuka kwi-fiber inputs ezimbini, i-GLB3500E-4R iye yakha imodyuli ye-SatCR yokutshintsha i-RF ebanzi ukusuka kwiisathelayithi ezimbini, ikhupha iibhendi ezi-4 zomsebenzisi wesathelayithi kwizibuko elinye le-SatCR RF kwi-4 unicable receiver satellite.

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. Iisathelayithi ezimbini eziqhelekileyo Inkqubo ye-SMATV idinga iintambo ze-9 ze-RF ukusuka kuphahla lwesakhiwo ukuya kwii-cascading multiswitch, ezikhonza ababhalisile abangaphantsi kwe-100 kwisakhiwo esinye. Kwiisathelayithi ezimbini ze-SMATV phezu kwefayibha, i-Greatway Technology ine-GLB3500M-8 njengesisombululo se-FTTB kunye ne-GLB3500E-4R njengesisombululo se-FTTH. Isisombululo se-FTTB kufuneka sibe ne-STB yesathelayithi eqhelekileyo, ngelixa isisombululo se-FTTH kufuneka sibe ne-STB yesathelayithi exhasa unicable.

I-GLB3500E-4R ine-1310nm/1490nm/1550nm izibuko le-WDM lokukhetha ukusebenzisana ne-GPON ONU nakwesiphi na isicelo se-FTTH, esenza ukuba iziqulatho ze-satellite ze-LNB zifakwe kwinkqubo ye-GPON.
