GLB3500A-2R Twin Fiber Optic LNB

GLB3500A-2R satellite LHCP/RHCP FTTH Optical LNB yog fiber ntau optic receiver converting optical teeb liab rau hauv RF rau ntau tshaj ob satellite receivers. Ua hauj lwm nrog Greatway GLB3500A-2T satellite TV fiber optic transmitter, GLB3500A-2R outputs zoo Terrestrial TV + LHCP thiab Terrestrial TV + RHCP RF teeb liab rau ib tsev neeg nrog ntau tshaj ob satellite receivers. Qhov FTTH Twin LNB no tuaj yeem muaj ob lub RF tso tawm, txhua qhov chaw nres nkoj RF tuaj yeem hloov LHCP lossis RHCP tso zis teeb liab los ntawm 13V lossis 18V DC lub zog los ntawm satellite txais.

Tsis tu ncuaLNByogLow uaNoiseBxauv, hloov Ku Band 10.7GHz ~ 12.75GHz RF lossis C Band 3.7GHz ~ 4.2GHz RF rau 950MHz ~ 2150MHz IF rau zaum txais. Ntawm SMATV tshaj fiber ntau, ib lub transmitter hloov LNB IF rau fiber ntau. Tom qab fiber ntau optic amplifier thiab PON, optic teeb liab tau muab faib rau ntau pua lossis ntau txhiab tsev neeg FTTH. Ntawm txhua lub tsev uas muaj fiber ntau cable, ib lub optical receiver converts fiber ntau rau Sat IF. Fiber input hloov mus rau 950MHz ~ 2150MHz IF tso zis rau sat receiver.

Satellite optical receiver plays tib lub luag haujlwm li LNB li niaj zaus, nws yog "virtual" LNB hauv tsev. Satellite optical receiver tuaj yeem hu ua Optical LNB lossis Fiber LNB.

Tsis tu ncua LNB raug teeb tsa ntawm lub phaj tig rau saum ntuj. Optical LNB tau teeb tsa nyob txhua qhov chaw hauv tsev uas muaj fiber ntau. Cov ntsiab lus ntawm ib qho LNB tsis tu ncua tuaj yeem rov tsim tawm txog 500K kho qhov muag LNBs

Li niaj zaus LNB muaj ntsug lossis kab rov tav polarities (13V / 18V) thiab siab dua band lossis qis qis (0Hz lossis 22KHz). Los ntawm txoj kev ntawm CWDM / DWDM thev naus laus zis, kho qhov muag LNB tuaj yeem muaj qhov ua haujlwm zoo ib yam RF chaw nres nkoj txhawb nqa DiSEqC.

GLB3500A-2R muaj 1310nm / 1490nm WDM kev xaiv rau kev ua haujlwm nrog GPON / EPON ONU hauv txhua rooj plaub FTTH, uas tso cai rau tso satellite TV hla GPON / EPON network.
