4 Intebe hejuru ya GPON
Nilesat, Eutelsat 8W, Badr 4/5/6/7 & Es'hail 2, Inyoni Ashyushye 13E ni satelite izwi cyane muburasirazuba bwo hagati.Abantu bakunda kubareba.Nakazi katoroshye kumuryango umwe gushiraho ibyokurya bine bya satelite byakira gusa icyogajuru.Nakazi katoroshye kubiyandikishije baba munzu imwe gusangira ibyokurya bine bya satelite hejuru yumurongo winsinga za coaxial.Internet nicyo kintu cyambere gisabwa kuri iyi si.Niba hari fibre ya GPON kuri buri mufatabuguzi, Greatway Technology yorohereza aka kazi kubiciro bidahenze.Iki cyifuzo gitanga igisubizo cya satelite 4 yatoranijwe izwi cyane ya FTA cyangwa ibanga ryibanga FTTH kubantu bagera kuri 2800 GPON ONU.
Transponders ya Satelite Yahinduwe na dCSS LNB muburyo buhagaze
Buri cyogajuru gifite transponders zigera kuri 10 ~ 96.Ibirimo 20% birakunzwe mubiyandikishije 80%.Kugirango tuzigame buri rugo rwa FTTH, duhitamo gusa transponders 32 zizwi cyane (32 Abakoresha bande) muri buri cyogajuru kugeza kumazu yose ya GPON.Kugirango ukore ibi, dukeneye 4pcs dCSS static LNB hamwe na 32UB yatoranijwe ya buri satelite..
Guhindura ibimenyetso bya DTT
DTT itangwa nabakozi bake mumujyi kandi iminara ya DTT ishobora guhagarara ahantu hatandukanye mumujyi.Ikimenyetso cya DTT kuruhande rwa umunara wa DTT gishobora kuba gikomeye kugirango winjire kuri televiziyo.Kugirango wirinde kwivanga inshuro imwe, birasabwa guhindura inshuro zose zitwara DTT mbere yo kohereza optique ya Terr TV.Muri uyu mushinga, hari abatwara RF 3 ku isi: VHF7 na UHF32, UHF36.Turasaba ko dukoresha televiziyo imwe ya GTC250 yo ku isi kugira televiziyo nshya ikurikira: VHF8, na UHF33 na UFH31 (Bitewe na PAL-B / G hamwe nibimenyetso bya DTT, turasaba VHF kuri VHF na UHF guhinduka UHF ).GTC250 ifite inyongeramusaruro enye za VHF / UHF hamwe nimwe igera kuri 32ch DTT RF isohoka.1pcs GTC250 irashobora gusohora isuku nziza yo hejuru 3ch DTT RF (buriwese kurwego rwa 85dBuV RF) kuri transmitter optique, kuyungurura cyangwa guhagarika ibimenyetso bya mobile 4G na 5G.
Ikwirakwiza ryiza
1s
GLB3500M-4TD optique yoherejwe igomba gushyirwaho mumazu.Umugozi wa RG6 coaxial kuri buri dCSS LNB uburebure bugomba kuba munsi ya metero 50.
Amahitamo meza
Kubera ko abafatabuguzi 2800 bose ba GPON bishyizwe hamwe na 1x16 itandukanya, hari byibuze amatsinda 175.
GLB3500M-4TD ifite ingufu zisohoka + 9dBm, izakurikirwa na 1pcs 1x4 PLC itandukanya mbere.Mubisohoka 4 bisohoka, ibisohoka 3 byahujwe na 3pcs imbaraga nyinshi GWA3500-34-64W.1 gutandukanya ibisohoka nkicyambu gihagaze.
Amashanyarazi meza
Buri GWA3500-34-64W yakira optique ifite 1550nm yinjiza optique, 64 OLT yinjiza, hamwe nicyambu 64 com, aho buri cyambu cya com gifite> + 12dBm @ 1550nm.Buri cyambu cya com gihujwe na 1x16 PON itandukanya, itanga TV yicaye hamwe na GPON Ethernet.
GWA3500-34-64W optique amplifier igomba gushyirwaho kuruhande rwa GPON OLT cyangwa hafi ya fibre fibre.3pcs GWA3500-34-64W amplificateur optique ifite ibyambu 192 bisohoka, usibye ibyambu 175 byahujwe, ibyambu bidakoreshwa nkibyambu bihagaze.
Sisitemu yambere ya GPON igomba kuba yashizwemo 1x16.Twabashyize kurutonde muri BOM niba ukeneye gutandukana 1x16.
Kwakira neza na GPON ONU
Kuri buri GPON ONU, turasaba gukoresha adapter imwe ya SC / UPC na metero 1 duplex SC / UPC kuri LC / UPC isimbuka, aho fibre 1 ihindura fibre SC / UPC yinjira muri LC / UPC kuri GLB3500M-4RH4-K optique LNB na the abandi bahinduranya ibimenyetso bya GPON bagaruka kuri SC / UPC kuri GPON ONU ihari.
GLB3500M-4RH4-K ifite ibyambu bine bya RF, buri cyambu cya RF gitanga ibyogajuru bya 4x32UB hamwe na TV yo ku isi.Niba hari decodeur zirenga 4 kuri buri GPON ONU, buri cyambu cya RF cya GLB3500M-4RH4-K gishobora guhuzwa numuyoboro umwe w’inzira 4 cyangwa inzira 8 kugirango ushyigikire ibyogajuru 16 cyangwa 32, aho icyogajuru cya satelite gifite icyambu kimwe cya RF cyanyuze DC gusa.Ikirangantego cyakira gihuza icyambu cya DC gitoranya 1 muri satelite enye, imashini ya satelite ihuza nta cyambu cya DC ireba ibintu 32 bya satelite byatoranijwe.
Ikirangantego
Kwakira icyogajuru gisanzwe gishyigikira ibyogajuru byinshi gushakisha birashobora kureba ibirimo byose bya FTA nibanga ryibanga hamwe namakarita ya CA.Nta mikorere idahwitse isabwa kuri satelite yakira.
Fibre Jumper
Bitewe n'ubucucike bwinshi EYDFA, dushobora gukoresha umuhuza LC / UPC aho gukoresha SC / UPC.Hagomba kubaho gusimbuka fibre patchcord nka LC / UPC kuri SC / UPC cyangwa LC / APC kuri SC / APC.
