GLB3500E-2R satellite TV FTTH Optical LNB waa aqbalaha fiber optic-ga oo u beddelaya signalka indhaha RF ilaa 4 satalayt qaatayaasha hal guri.La shaqaynta Greatway GLB3500E-2T satellite TV-ga gudbiyaha indhaha, GLB3500E-2R waxa ay ku dhex dhisantay moduleka SatCR oo la tacaalaya dayax gacmeedka RF, waxa uu soo saara 4 satalaytka isticmaala hal deked SatCR RF oo loogu talagalay 4 qaata satalaytka oo aan awood u lahayn.

LNB-ga joogtada ahi waa Block sanqadh hooseeya, oo u beddelaya Ku Band 10.7GHz~12.75GHz RF ama C Band 3.7GHz~4.2GHz RF ilaa 950MHz~2150MHz HADDII loogu talagalay qaataha fadhiga.Marka SMTV ka sarreeya nidaamka fiber-ka, hal gudbiye ayaa u beddela LNB HADDII fiber.Kadib cod-weyneeye fiber optic iyo PON, signalka optic-ga waxa loo qaybiyaa boqollaal ama kumanaan qoys oo FTTH ah.Guri kasta oo leh fiilada fiber-ka, mid ka mid ah qaataha indhaha ayaa fiber u beddela Sat IF.Gelitaanka fiber-ku wuxuu noqdaa 950MHz ~ 2150MHz HADDII wax soo saarka sat qaataha.

Satellite optical receiver wuxuu ciyaaraa door la mid ah kan caadiga ah ee LNB, waa "virtual" LNB guriga.Satellite optical receiver waxaa loogu yeeri karaa Optical LNB ama Fiber LNB.

LNB joogto ah ayaa lagu rakibay saxanka cirka u jeeda.Optical LNB waxa lagu rakibay meel kasta oo guriga ka mid ah oo fiber laga heli karo.Waxa ku jira hal LNB oo caadi ah ayaa dib loo soo saari karaa ilaa 500K indhaha LNBs.

LNB-da caadiga ah waxay leedahay tiirar toosan ama toosan (13V/18V) iyo band sare ama qayb hoose (0Hz ama 22KHz).Iyada oo la adeegsanayo tignoolajiyada CWDM/DWDM, indhaha LNB waxay yeelan karaan shaqo isku mid ah dekedda RF ee taageerta DiSEqC.

GLB3500E-2R waxay haysataa 1310nm/1490nm/1550nm WDM doorasho deked ah oo wada shaqayn la leh GPON ONU codsi kasta oo FTTH ah, kaas oo awood u siinaya waxyaabaha ku jira dayax gacmeedka Quattro LNB in la geliyo nidaamka GPON.
