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.
