GLB3500A-2R Twin Fiber Optic LNB

GLB3500A-2R dayax-gacmeedka LHCP/RHCP FTTH Optical LNB waa aqbalaha fiber optic-ka ee u beddela signalka indhaha RF in ka badan laba satalayt qaatayaal. La shaqaynta Greatway GLB3500A-2T satellite TV fiber optic transmitter, GLB3500A-2R waxay soo saartaa tayada sare ee Terrestrial TV+ LHCP iyo Terrestrial TV FTTH Twin LNB waxay lahaan kartaa laba wax soo saar oo RF ah, deked kasta oo RF ah waxay bedeli kartaa calaamada wax soo saarka LHCP ama RHCP 13V ama 18V DC ee satalaytka qaata.

Joogto ahLNBwaaLowNsaliidBquful, 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 fibre optic amplifier iyo PON, signalka indhaha 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 waxa uu ka ciyaaraa door la mid ah kan caadiga ah ee LNB, waa "virtual" LNB guriga. Satelite-ka qaataha indhaha waxa 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 caadi ah ayaa dib loo soo saari karaa ilaa 500k LNB-yada indhaha

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.

GLB3500A-2R waxay haysataa 1310nm/1490nm WDM ikhtiyaar ah oo loogu talagalay la shaqaynta GPON/EPON ONU kiis kasta oo FTTH ah, kaas oo awood u siinaya gelinta satellite-ka ee shabakada GPON/EPON.
