GLB3500E-2R FTTH LNB
Product Description
GLB3500E-2R satellite TV FTTH Optical LNB yog fiber ntau optic receiver converting optical teeb liab rau hauv RF rau txog li 4 satellite receivers nyob rau hauv ib lub tsev. Ua hauj lwm nrog Greatway GLB3500E-2T satellite TV optical transmitter, GLB3500E-2R muaj built-in SatCR module cuam tshuam nrog wideband satellite RF, outputs 4 satellite neeg siv bands ntawm ib tug SatCR RF chaw nres nkoj rau 4 unicable satellite receivers.
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.
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.
GLB3500E-2R muaj 1310nm / 1490nm / 1550nm WDM xaiv chaw nres nkoj rau kev ua haujlwm nrog GPON ONU hauv txhua daim ntawv thov FTTH, uas ua rau cov xov tooj cua qub Quattro LNB cov ntsiab lus tau muab tso rau hauv GPON system.
Lwm yam nta:
•High Linearity Photodiode.
•SC / APC fiber ntau input.
•Optical AGC ntau yam: -6dBm ~ +1dBm.
•Ib qho SatCR RF chaw nres nkoj rau txog li 4 tus neeg txais tsis tuaj yeem zaum hauv ib lub tsev.
•Sat RF txwv: 950 ~ 2150MHz.
•CE pom zoo.
