GLB3500E-2R tauraron dan adam TV FTTH Optical LNB shine mai karɓar fiber optic yana jujjuya siginar gani zuwa RF don har zuwa 4 tauraron dan adam masu karɓa a gida ɗaya.Aiki tare da Greatway GLB3500E-2T tauraron dan adam TV na gani watsawa, GLB3500E-2R ya gina-in SatCR module ma'amala da wideband tauraron dan adam RF, fitarwa 4 tauraron dan adam makada masu amfani a daya SatCR RF tashar jiragen ruwa ga 4 unicable tauraron dan adam masu karɓa.
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.
LNB na yau da kullun yana da polarities a tsaye ko a kwance (13V/18V) da babbar band ko ƙananan band (0Hz ko 22KHz).Ta hanyar fasahar CWDM/DWDM, LNB na gani na iya samun aikin tashar tashar RF iri ɗaya mai goyan bayan DiSEqC.
GLB3500E-2R yana da 1310nm/1490nm/1550nm WDM tashar zaɓi don aiki tare da GPON ONU a cikin kowane aikace-aikacen FTTH, wanda ke ba da damar shigar da abun ciki na tauraron dan adam Quattro LNB na gargajiya a cikin tsarin GPON.
Wasu Fasaloli:
•Babban Linearity Photodiode.
•SC/APC Fiber shigarwar.
•Kewayon AGC na gani: -6dBm ~ +1dBm.
•Ɗaya daga cikin tashar jiragen ruwa na SatCR RF don har zuwa 4 masu karɓar zama marasa aiki a gida ɗaya.
•Sat RF Ban: 950 ~ 2150MHz.
•CE ta amince.
