4 Inogara pamusoro peGPON
Nilesat, Eutelsat 8W, Badr 4/5/6/7 & Es'hail 2, Hot Bird 13E ndiwo masatelliti anozivikanwa ari pakati pekumabvazuva. Vanhu vanofarira kuvaona. Ibasa rakaoma kumhuri imwe chete kuisa madhishi mana esatellite anoshanda chete setiraiti inogamuchira. Iri ibasa rakaoma kune vanyoreri vanogara muchivako chimwe kuti vagovane madhishi mana esatellite pamusoro pemusumbu wetambo dzekoaxial. Internet ndiyo inonyanya kukosha kudiwa pasi pano. Kana paine GPON faibha kune mumwe nemumwe anyoresa, Greatway Technology inoita kuti basa iri rive nyore nemutengo unokwanisika. Chikumbiro ichi chinopa mhinduro yemasetelliti mana akasarudzwa anonyanya kufarirwa FTA kana encrypted zvirimo FTTH kune vangangoita mazana maviri nemazana masere ezviuru GPON ONU vanyoreri.
Satellite Transponders Yakagadziriswa neGSS32 dCSS Satellite Converter
Imwe neimwe setiraiti ine inosvika gumi ~ 96 transponders kubva yakajairwa Quattro LNB. 20% zviri mukati zvinozivikanwa mu80% vanyoreri. Tichashandisa satellite converter (4 yakazvimiririra yakagara mapeji uye imwe 950 ~ 2150MHz satellite kubuda) kusarudza izvo zvinodikanwa setiraiti zvirimo kuFTTH system. Kuti tiite izvi, tinoda 4pcs GSS32 dCSS satellite converters kuti tive nepamusoro 128 transponders (128 User Bands) kubva kune aya 4 satellites (Ndapota taura neGreatway Technology yemutungamiri wekushanda).
DTT chiratidzo chekushandura
DTT inopihwa nevashoma vanoshanda muguta uye iyo DTT inotumira shongwe inogona kumira munzvimbo dzakasiyana dzeguta. Chiratidzo cheDTT padivi peDTT tower inogona kunge yakasimba kupinda muTV yakananga. Kuti udzivise kupindira kwakafanana, zvinokurudzirwa kushandura ese DTT mutakuri frequency pamberi peiyo optical transmitter Terr TV yekuisa. Muchirongwa ichi, kune vatatu veTerestrial RF vatakuri: VHF7 uye UHF32, UHF36. Isu tinokurudzira kushandisa imwe GTC250 yeterrestrial TV frequency converter kuti ive neinotevera Terrestrial TV frequency: VHF8, uye UHF33 uye UFH31 (Nekuda kwePAL-B/G chiyero uye DTT masaini maficha, isu tinokurudzira VHF kuenda kuVHF uye UHF kuUHF shanduko. ) GTC250 ine ina VHF/UHF yekupinda uye imwe inosvika pakakwirira 32ch DTT RF kubuda. 1pcs GTC250 inogona kuburitsa yakachena mhando 3ch DTT RF (imwe neimwe pa85dBuV RF level) kune transmitter yemaziso, kusefa kana kuvhara 4G uye 5G nharembozha.
Optical Transmitter
1pcs GLB3500M-4TD DWDM optical transmitter inogamuchira 4x32UB setiraiti yekupinda uye imwe GTC250 yepasi RF yekuisa, ichishandura ese pamusoro pe1550nm DWDM.SM fiber.
GLB3500M-4TD Optical transmitter inofanira kuiswa mukati. Iyo RG6 coaxial tambo kureba kubva kune yega yega Quattro LNB kuenda kuGSS32 setiraiti inoshandura inofanira kunge iri pasi pe50 metres.
Optical Splitter
Sezvo vese 2800 GPON vanyoreri vakaunganidzwa ne 1x16 splitter, pane anokwana 175 mapoka.
GLB3500M-4TD ine simba re +9dBm rekubuda, iro richateverwa ne1pcs 1x4 PLC splitter kutanga. Pakati pezvina kupatsanurwa zvakabuda, 3 splitter zvinobuda zvakabatana ne3pcs yakakwirira simba GWA3500-34-64W zvichiteerana. 1 splitter inobuda sechiteshi chekumira.
Optical Amplifier
Imwe neimwe GWA3500-34-64W inogamuchira yekuona ine imwe 1550nm yekupinza yemaziso, 64 OLT mapipu, uye 64 com ports, uko imwe neimwe com ports ine >+12dBm@1550nm. Imwe neimwe com port yakabatana ne 1x16 PON splitter, ichipa ese akagara TV uye GPON Ethernet.
GWA3500-34-64W optical amplifier inofanira kuiswa pedyo neGPON OLT kana pedyo nefiber cable hub. 3pcs GWA3500-34-64W optical amplifiers ane 192 anobuda ports, kunze kwe175 akabatana madoko, madoko asina kushandiswa seakamira madoko.
Iyo yaimbova GPON system inofanirwa kuve ne 1x16 splitter yakaiswa. Isu takavanyora muBOM kana iwe uchida 1x16 splitter.
Optical Receiver uye GPON ONU
Pane yega yega GPON ONU, tinokurudzira kushandisa imwe SC/UPC adapta uye 1 mita duplex SC/UPC kuenda kuLC/UPC jumper, uko 1 fiber inoshandura inouya SC/UPC fiber kuita LC/UPC kuita GLB3500M-4RH4-K optical LNB uye imwe inoshandura loop out GPON siginecha kudzokera kuSC/UPC kune iripo GPON ONU.
GLB3500M-4RH4-K ine ina RF zviteshi, imwe neimwe RF port inopa 4x32UB satellite zviri mukati uye yepanyika TV. Kana paine anopfuura mana setiraiti madhikodha panzvimbo yega yega yeGPON ONU, chiteshi chega chega cheRF cheGLB3500M-4RH4-K chinogona kubatanidzwa neimwe 4-nzira kana 8-nzira satellite splitter kutsigira gumi nematanhatu kana 32 vanogamuchira setiraiti, uko satellite splitter ine. imwe RF port pass DC chete. Iyo setiraiti inogamuchira inobatanidza neDC inopfuura chiteshi inosarudza 1 pamasatelliti mana, satellite inogamuchira inobatanidza pasina DC port inoona zvakasarudzwa 32UB zvirimo zvesatelliti.
Satellite Receiver
Yenguva dzose satellite inogamuchira inotsigira akawanda satellite zvirimo kutsvaga inogona kuona zvese zvirimo muFTA uye zvakavharidzirwa zvirimo neCA kadhi. Hapana unicable basa rinodiwa pane satellite inogamuchira.
Fiber Jumper
Nekuda kwekuwanda kweEYDFA, tinogona kushandisa LC/UPC yekubatanidza panzvimbo yeSC/UPC yekubatanidza. Panofanira kuve nekusvetuka fiber patchcord seLC/UPC kuenda kuSC/UPC kana LC/APC kuenda kuSC/APC.
