GLB3500M-4D Plaub Satellites DWDM FTTH nrog GPON
Product Description
GLB3500M-4D yog modular DWDM broadband RF fiber txuas, xa plaub 950 ~ 2150MHz Satellite RF thiab ib qho 174 ~ 806MHz Terrestrial TV RF tshaj ib qho SM fiber ntau rau cov neeg siv FTTH ntau. Plaub satellite RFs tuaj yeem yog VL / VH / HL / HH los ntawm ib qho Quattro LNB lossis plaub qhov zoo li qub 32UB los ntawm plaub lub satellite dCSS LNBs.
Plaub satellites muaj ntau lub transponders ntawm txhua lub satellite. Qhov tseeb, tsuas yog 20% cov ntsiab lus ntawm satellite yog nrov hauv 80% cov neeg siv khoom. Tag nrho cov ntsiab lus los ntawm plaub satellites tshaj coaxial cable rau fiber ntau cable rau txhua lub tsev yog kim. GLB3500M-4D system xaiv cov transponders nrov tshaj plaws rau txhua tus neeg siv khoom. 32 transponders los ntawm txhua lub satellite yuav tsum suav nrog cov ntsiab lus tshwj xeeb tshaj plaws ntawm satellite. Nrog 4ch DWDM tshuab thiab lub zog siab 1550nm optical amplifier, GLB3500-4D tuaj yeem ntxig 4 satellites nrog tag nrho 128 transponders rau hauv ib qho GPON lossis XGPON system. Ntawm dCSS LNB hom zoo li qub, cov satellite txais tuaj yeem yog hom tsis tu ncua saib tag nrho 4 satellite xaiv cov ntsiab lus.
GLB3500M-4D fiber ntau txuas suav nrog GLB3500M-4TD DWDM optical transmitter thiab GLB3500M-4RD4 FTTH optical receiver. Optical receiver muaj 4 RF chaw nres nkoj, txhua qhov chaw nres nkoj txhawb saib cov khoom xa tuaj 32UB ntawm cov khoom xa tuaj. Nrog DWDM lasers / photodiode thiab tsis tshua muaj suab nrov RF nce tswj Circuit Court, ib qho GLB3500M-4TD tuaj yeem xa cov khoom zoo RF mus rau siab tshaj 32 GLB3500M-4RD4 optic receivers ncaj qha los yog ntau txhiab GLB3500M-4RD4 optic receivers ntawm lub hwj chim optical amplifier.
