GFH2000-K TV da Sat Fiber Optic LNB
Bayanin Samfura
GFH2000-K shine 45 ~ 2600MHz 1550nm fiber optic mai karɓa tare da tashar WDM zuwa FTTH ONU.A matsayin tushen fiber na gani LNB, GFH2000-K yana da wideband LNB (300MHz ~ 2350MHz) ko na yau da kullun LNB (950MHz ~ 2150MHz) + CATV RF makada, yana aiki tare da GWT3500S (CATV + Sat) fiber optic transmitter ko GLB3500r TV-D (T) Sat IF) fiber optic transmitter ko wideband na gani watsawa.
LNB na yau da kullun shine Ƙarshen Noise Block, yana jujjuya Ku Band 10.7GHz~12.75GHz RF ko C Band 3.7GHz~4.2GHz RF zuwa 950MHz~2150MHz IF don mai karɓar sat.A SMTV akan tsarin fiber, mai watsawa ɗaya yana canza LNB IF zuwa fiber.Bayan fiber optic amplifier da PON, ana rarraba siginar gani zuwa ɗaruruwa ko dubban iyalai na FTTH.A kowane gida mai kebul na fiber, mai karɓar gani ɗaya yana canza fiber zuwa Sat IF.Shigar fiber yana juya zuwa 950MHz ~ 2150MHz IDAN fitarwa don mai karɓar sat.
Mai karɓar gani na tauraron dan adam yana taka rawa iri ɗaya da LNB na yau da kullun, LNB “mai kama-da-wane” ne a gida.Ana iya kiran mai karɓar gani na tauraron dan adam a matsayin Optical LNB ko Fiber LNB.
Ana shigar da LNB na yau da kullun a tasa tana fuskantar sama.Ana shigar da LNB na gani a ko'ina cikin gida inda fiber ke samuwa.Ana iya sake samar da abubuwan da ke cikin LNB guda ɗaya na yau da kullun har zuwa 500K LNBs na gani.
A matsayin LNB na gani na duniya, GFH2000-K na iya aiki tare da kowane ɓangare na uku GPON ONU ko 1270nm/1577nm XGPON ONU ko 1524 ~ 1544/1596 ~ 1599nm NGPON2 ONU, saka babbar ingancin watsa shirye-shiryen CATV+SAT ba tare da biyan kuɗi zuwa Intanet ba. bandwidth.
