GLB2000A-K Terr TV thiab Fiber Optic Twin LNB
Product Description
GLB2000A satellite TV FTTH kho qhov muag LNB hloov kho qhov muag teeb liab rau hauv ob lub polarities RF rau ib lub satellite txais.Ua hauj lwm nrog Greatway GLB3500A-2T satellite TV fiber optic transmitter, GLB2000A outputs zoo Terrestrial TV + Vertical / Kab rov tav RF teeb liab.Qhov ftth LNB no tuaj yeem hloov Vertical (lossis RHCP) lossis Kab rov tav (lossis LHCP) tso zis teeb liab los ntawm 13V lossis 18V DC lub zog los ntawm satellite txais.
Tsis tu ncua LNB yog Tsis tshua muaj suab nrov Block, converting Ku Band 10.7GHz ~ 12.75GHz RF los yog C Band 3.7GHz ~ 4.2GHz RF rau 950MHz ~ 2150MHz IF rau zaum receiver.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
• Tsis tu ncua 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 los ntawm ib qho SM fiber ntau.
