GFH2000-K TV thiab Sat Fiber Optic LNB
Product Description
GFH2000-K yog 45 ~ 2600MHz 1550nm fiber optic receiver nrog WDM chaw nres nkoj rau FTTH ONU. Raws li ib qho yooj yim fiber ntau optic LNB, GFH2000-K muaj wideband LNB (300MHz ~ 2350MHz) los yog li niaj zaus LNB (950MHz ~ 2150MHz) + CATV RF bands, nws ua hauj lwm nrog GWT3500S (CATV + Sat) fiber optic transmitter los yog GLB3500rMT-D Sat IF) fiber ntau optic transmitter lossis wideband optical transmitter.
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.
Raws li universal kho qhov muag LNB, GFH2000-K tuaj yeem ua haujlwm nrog lwm tus neeg sab nrauv GPON ONU lossis 1270nm / 1577nm XGPON ONU lossis 1524 ~ 1544 / 1596 ~ 1599nm NGPON2 ONU, ntxig cov xov xwm zoo tshaj plaws hauv CAFT + SAT cov yeeb yaj kiab hauv internet bandwidth.
Lwm yam nta:
•High Linearity Photodiode rau Terrestrial TV thiab Satellite TV RF.
•45MHz ~ 2600MHz (downstream) RF tso zis.
•1270nm / 1577nm Optical Bypass chaw nres nkoj rau XGPON ONU kev xaiv.
•1524 ~ 1544nm / 1596 ~ 1599nm bypass chaw nres nkoj rau NGPON2 ONU kev xaiv.
•DC fais fab tuag thiab kho qhov muag input LED taw qhia.
•Kev ywj pheej 10 ~ 18V DC fais fab adapter chaw nres nkoj.
