4 Sats dhau GPON
Nilesat, Eutelsat 8W, Badr 4/5/6/7 & Es'hail 2, Kub noog 13E yog cov nrov satellites nyob rau hauv nruab nrab sab hnub tuaj. Cov neeg nyiam saib lawv. Nws yog ib txoj hauj lwm nyuaj rau ib tsev neeg los nruab plaub lub satellite tais diav uas tsuas yog siv ib lub receiver satellite xwb. Nws yog ib txoj hauj lwm nyuaj rau cov neeg nyob hauv ib lub tsev los qhia plaub lub satellite tais diav hla ib pob ntawm coaxial cables. Internet yog qhov tseem ceeb tshaj qhov xav tau ntawm lub ntiaj teb no. Yog tias muaj GPON fiber ntau rau txhua tus neeg siv khoom, Greatway Technology ua rau txoj haujlwm no yooj yim dua ntawm tus nqi pheej yig. Lub tswv yim no muab kev daws teeb meem ntawm 4 satellites xaiv FTA nrov tshaj plaws lossis cov ntsiab lus zais FTTH txog li 2800 GPON ONU cov neeg siv khoom.
Satellite Transponders Kho los ntawm GSS32 dCSS Satellite Converter
Txhua lub satellite muaj txog 10 ~ 96 transponders los ntawm Quattro LNB li niaj zaus. 20% cov ntsiab lus yog nrov hauv 80% cov neeg siv khoom. Peb yuav tsum siv satellite converter (4 ywj siab zaum inputs thiab ib tug 950 ~ 2150MHz satellite tso zis) los xaiv cov xav satellite txheem rau FTTH system. Ua li no, peb xav tau 4pcs GSS32 dCSS satellite converters kom muaj ntau tshaj 128 transponders (128 User Bands) los ntawm 4 satellites (Thov hu rau Greatway Technology rau cov lus qhia ua haujlwm).
DTT teeb liab conversion
DTT yog muab los ntawm ob peb tus neeg ua haujlwm hauv nroog thiab DTT cov xaim hluav taws xob tuaj yeem sawv hauv ntau qhov chaw hauv nroog. Lub teeb liab DTT nyob ib sab ntawm DTT ntauwd tej zaum yuav muaj zog nkag mus rau TV teeb ncaj qha. Txhawm rau kom tsis txhob cuam tshuam tib zaus, nws raug nquahu kom hloov tag nrho DTT cov cab kuj zaus ua ntej lub transmitter kho qhov muag Terr TV input. Hauv qhov project no, muaj 3 Terrestrial RF nqa: VHF7 thiab UHF32, UHF36. Peb xav kom siv ib qho GTC250 terrestrial TV zaus converter kom muaj cov nram qab no tshiab Terrestrial TV zaus: VHF8, thiab UHF33 thiab UFH31 (Vim PAL-B / G tus qauv thiab DTT teeb liab nta, peb pom zoo VHF rau VHF thiab UHF rau UHF hloov dua siab tshiab ). GTC250 muaj plaub VHF / UHF inputs thiab ib txog li 32ch DTT RF tso zis ntau tshaj. 1pcs GTC250 tuaj yeem tso tawm cov khoom zoo 3ch DTT RF (txhua ntawm 85dBuV RF qib) mus rau qhov muag transmitter, lim lossis thaiv 4G thiab 5G mobile signals.
Optical Transmitter
1pcs GLB3500M-4TD DWDM optical transmitter tau txais 4x32UB satellite inputs thiab ib qho GTC250 terrestrial RF input, converting tag nrho lawv tshaj 1550nm DWDMSM fiber ntau.
GLB3500M-4TD optical transmitter yuav tsum tau muab tso rau sab hauv tsev. Lub RG6 coaxial cable ntev los ntawm txhua Quattro LNB rau GSS32 satellite converter yuav tsum tsawg dua 50 meter.
Optical Splitter
Txij li tag nrho 2800 GPON cov neeg siv khoom tau muab faib ua 1x16 splitter, muaj tsawg kawg yog 175 pawg.
GLB3500M-4TD muaj txog +9dBm tso zis zog, uas yuav tsum tau ua raws li 1pcs 1x4 PLC splitter ua ntej. Ntawm cov 4 splitter outputs, 3 splitter outputs txuas nrog 3pcs siab zog GWA3500-34-64W feem. 1 splitter tso zis raws li standby chaw nres nkoj.
Optical Amplifier
Txhua GWA3500-34-64W optical receiver muaj ib qho 1550nm optical input, 64 OLT inputs, thiab 64 com ports, qhov twg txhua qhov chaw nres nkoj muaj> + 12dBm @ 1550nm. Txhua qhov chaw nres nkoj com txuas nrog 1x16 PON splitter, muab ob qho tib si zaum TV thiab GPON Ethernet.
GWA3500-34-64W optical amplifier yuav tsum tau nruab ib sab ntawm GPON OLT los yog ze rau lub fiber cable hub. 3pcs GWA3500-34-64W optical amplifiers muaj 192 qhov chaw tso zis, dhau li ntawm 175 cov chaw nres nkoj txuas, cov chaw nres nkoj tsis siv ua cov chaw nres nkoj.
Cov qub GPON system yuav tsum muaj 1x16 splitter ntsia. Peb teev lawv hauv BOM yog tias koj xav tau 1x16 splitter.
Optical Receiver thiab GPON ONU
Ntawm txhua GPON ONU, peb xav kom siv ib qho SC / UPC adapter thiab 1 meter duplex SC / UPC rau LC / UPC jumper, qhov twg 1 fiber hloov cov khoom SC / UPC fiber ntau rau LC / UPC rau GLB3500M-4RH4-K optical LNB thiab cov lwm yam hloov lub voj tawm GPON teeb liab rov qab rau SC / UPC rau GPON ONU uas twb muaj lawm.
GLB3500M-4RH4-K muaj plaub qhov chaw nres nkoj RF, txhua qhov chaw nres nkoj RF muaj 4x32UB satellite cov ntsiab lus thiab cov TV hauv av. Yog hais tias muaj ntau tshaj 4 satellite decoders ntawm txhua qhov chaw GPON ONU, txhua qhov chaw RF ntawm GLB3500M-4RH4-K tuaj yeem txuas los ntawm ib qho 4-txoj kev lossis 8-txoj kev satellite splitter los txhawb 16 lossis 32 satellite receivers, qhov twg satellite splitter muaj ib qho RF chaw nres nkoj dhau DC nkaus xwb. Lub satellite receiver txuas nrog DC hla chaw nres nkoj xaiv 1 ntawm plaub lub satellites, cov satellite receivers txuas ntawm tsis muaj DC chaw nres nkoj saib cov xaiv 32UB satellite ntsiab lus.
Satellite txais
Cov neeg txais xov tooj cua tsis tu ncua uas txhawb nqa ntau cov ntsiab lus satellites tshawb nrhiav tuaj yeem saib tag nrho cov ntsiab lus FTA thiab cov ntsiab lus zais nrog CA daim npav. Tsis muaj qhov yuav tsum tau ua haujlwm tsis zoo ntawm lub satellite txais.
Fiber Jumper
Vim yog qhov ceev EYDFA, peb yuav siv LC / UPC connector es tsis txhob SC / UPC connector. Yuav tsum muaj qee qhov dhia fiber ntau patchcord xws li LC / UPC rau SC / UPC lossis LC / APC rau SC / APC.
