Yog hais tias ib tug satellite muaj nplua nuj transponders, lub transponders nyob rau ntawm ob polarities: Vertical thiab kab rov tav los yog sab laug tes voj voog polarity (LHCP) thiab sab tes xis voj voog polarity (RHCP). Tsis tu ncua satellite receiver tuaj yeem nyeem RF bandwidth ntawm 950 ~ 2150MHz. Muaj ntau tshaj 32 transponders los ntawm 950MHz txog 2150MHz.
Twin LNB yuav tau xaiv LO zaus los ntawm satellite MSO. Ob lub RF tso zis yog Vertical (RHCP) thiab Kab rov tav (LHCP), txhua tus muaj bandwidth ntawm 950 ~ 2150MHz. Yog hais tias tus xov tooj satellite tag nrho cov transponder tsawg dua 64, peb tuaj yeem siv cov kev daws teeb meem hauv qab no los faib cov ntsiab lus satellite no rau ntau txhiab lub tsev ntawm fiber ntau.
Hauv daim duab saum toj no, GLB3500A-2T optical transmitter converts ntxaib LNB RFs thiab Terrestrial TV (174 ~ 700MHz) RF rau hauv ib qho 1550nm fiber ntau los ntawm ib lub tsev ru tsev. Optical tso zis ntawmGLB 3500A-2Ttuaj yeem tsav 32pcs optical receivers ncaj qha los ntawm PLC fiber ntau splitter, qhov twg ib qhoHLB 2000Aoptical receiver muaj satellite thiab Terr TV teeb liab rau ib qho STB thiab TV hauv ib chav tsev,GLB3500A-2WRoptical receiver txhawb nqa ib qho chaw Terr TV rau ntau lub TVs thiab 4 zaum STBs hauv ib chav tsev. Yog tias tus naj npawb ntawm cov neeg siv khoom ntau dua li ntau pua lossis ntau txhiab tus neeg hauv zej zog lossis hauv nroog, peb yuav tsum muaj ib lub tshuab hluav taws xob kho qhov muag GWA3530 tom qab GLB3500A-2T optical transmitter.HWV 3530optical amplifier muaj 8 lossis 16 lossis 32 lossis 64 chaw nres nkoj, txhua qhov chaw nres nkoj tuaj yeem tsav 16 lossis 32 lossis 64 optical receivers. Hauv lwm lo lus, GWA3530 tuaj yeem tsav 1024 optical receivers lossis 2048 optical receivers lossis 4096 optical receivers hauv 20Km fiber ntau. Nrog kev xaiv OLT qhov chaw nres nkoj, GWA3530 tuaj yeem ntxig satellite TV RF hla tib lub fiber ntau ntawm GPON lossis XGPON network.
Qhov zoo ntawm satellite TV FTTH:
- Ib lub tais rau 32 tus neeg siv lossis ntau txhiab tus neeg siv khoom
- Zoo dua Satellite teeb liab zoo ntawm txhua lub davhlau ya nyob twg fiber ntau
- Fiber davhlau ya nyob twg yog ib qho yooj yim installation nyob rau hauv 5 feeb los ntawm "plug thiab ua si" tsim
- Tsis tu ncua satellite receiver
Yog hais tias muaj ntau tshaj 32 satellite transponders nyob rau hauv txhua satellite polarity, lub qis band thiab siab dua band (nyob rau hauv 22KHz tone) yog qhia kom tau raws li ib txwm satellite receiver 950MHz ~ 2150MHz zaus ntau. Ob chav wideband LNBGWB 104Gmuaj 10.4GHz LO zaus thiab RF tso zis bandwidth ntawm 300MHz ~ 2350MHz, piv txwv li, wideband Vertical RF yog sib npaug rau Vertical Lower (VL) thiab Vertical Higher (VH) thaum wideband Kab rov tav RF yog sib npaug rau Kab rov tav qis (HL) thiab Horizontal ). Txawm li cas los xij, wideband RF bandwidth dhau ntawm RF bandwidth ntawm satellite txais, peb xav tau Digital Channel Satellite Switcher (dCSS) nti los hloov wideband RF mus rau ntau yam ntawm satellite receiver. Tsis tas li ntawd, lub receiver satellite yuav tsum txhawb nqa tus qauv tsis raug.
Hauv daim duab saum toj no,GLB3500E-2Toptical transmitter converts ntxaib wideband LNB RFs thiab Terrestrial TV (Max 7ch VHF, 174 ~ 250MHz) RF rau hauv ib tug 1550nm fiber ntau los ntawm ib lub tsev ru tsev. Qhov tso zis kho qhov muag ntawm GLB3500E-2T tuaj yeem tsav 32pcs optical receivers ncaj qha lossis ntau txhiab tus optical receivers los ntawmHWV 3530amplifier. Ntawm txhua chav tsev, ib qhoGLB3500E-2WRoptical receiver txhawb 4 unicable satellite receivers.
Hauv Tebchaws Europe, muaj ntau dua 7 DTT channels (174 ~ 700MHz), peb muaj cov duab hauv qab no los faib cov ntsiab lus ntawm satellite (xws li Hot Bird 13E) thiab ntau tshaj 28 DTT channels.
Hauv daim duab saum toj no,GLB3500E-3Toptical transmitter converts ntxaib wideband LNB RFs thiab Terrestrial TV (174 ~ 700MHz) RF rau hauv ib lub 1550nm fiber ntau los ntawm ib lub tsev ru tsev. Optical tso zis ntawm GLB3500E-3T tuaj yeem tsav 32pcs optical receivers ncaj qha los yog ntau txhiab tus optical receivers los ntawmHWV 3530amplifier. Ntawm txhua chav tsev, ib qhoGLB3500-3WRoptical receiver muaj ib lub Terr TV chaw nres nkoj rau ntau lub TVs thiab ib tug zaum chaw nres nkoj rau 4 unicable satellite receivers.
