Ngo-Agasti 2, 2022, iGreatway Technology yabhengeza ukukhulula i-GLB3500M-6 imodyuli ye-6ch RF ngaphezulu kwesidluliseli sefayibha enye kunye nomamkeli.I-GLB3500M-6 inobude obuyi-6ch CWDM ngaphezu kwefayibha enye ye-SM ukuya kwenye okanye i-multiple optical receiver, apho i-wavelength nganye ye-CWDM ithwala i-wideband ye-174MHz ~ 2350MHz, kuquka iTerrestrial TV 174~806MHz okanye 950~2150MHz okanye indibaniselwano ye-Terr TV kunye ne-ensuring egqwesileyo. Umgangatho wesiginali yeRF kunye nokwahlukaniswa phakathi kweempawu zeRF.
Xa kuthelekiswa nesathelayithi RF phezu kwentambo yecoaxial ukuya kwi-TV Headend, i-GLB3500M-6 ineenzuzo ezintathu: 1. Ubuninzi be-eriyali yesathelayithi ezi-6 RFs ngaphezu kwe-SM fiber enye ukuya kwi-ofisi ye-Headend kunye nomgama omde kakhulu ukusuka kwi-100 yeemitha ukuya kwi-10Km;2. Ukukhuselwa kokukhanyisa kwizixhobo ze-Headhead ngenxa yentambo yefiber engaqhubekiyo;3. Ukwahlukaniswa komhlaba phakathi kweendawo zeSatellite dish kunye nendawo yesixhobo se-Headend.
I-GLB3500M-6 ikwabonelela ngokuguquguquka kwenkqubo ye-SMATV (iSatellite Master Antenna TV).Unikezelo lwamandla umva lwe-DC kwi-LNB lunokuba yiyo nayiphi na i-13V, 18V, 13V 22KHz, 18V 22KHz okanye akukho mbane weDC, usetwe kwangaphambili kumzi-mveliso.
I-GLB3500M-6 inokunikezela nge-eriyali zesathelayithi ezi-6 ubuninzi beempawu ze-RF okanye imixholo epheleleyo yeesathelayithi ezi-3 kwifayibha enye ukuya kwizakhiwo ezininzi kunye nababhalisi kumgama we-5Km weradius fiber.Kunye ne-PLC i-fiber splitter kunye ne-cascading multiswitch kwisakhiwo ngasinye, i-GLB3500M-6 inokusasaza ii-antenna ezininzi ze-satellite RFs kunye ne-Terr TV kwinani lababhalisi kuluntu.
I-GLB3500M-6 i-fiber link iquka i-GLB3500M-6T i-optical transmitter kunye ne-GLB3500M-6R i-optical receiver.Nge-CWDM lasers/photodiode kunye nesandi esiphantsi se-RF yokulawula ukufumana isiphaluka, enye i-GLB3500M-6T inokuhambisa umgangatho ophezulu we-RF ukuya kuma-32 GLB3500M-6R abamkeli be-optical.
Ifumaneka e-Shenzhen, i-Greatway Technology yi-RF phezu kwe-fiber yokuhanjiswa kwemveliso yoyilo lwendlu kunye nomzi-mveliso ukususela ngo-2004, inikezela nge-FTTH CATV receiver, RFoG ONU ye-ftth cable modem, i-satellite single / Twin / Quatro LNB RF phezu kwe-GPON, iisathelayithi ezimbini / ezine phezu kwefayibha enye. ikhonkco, i-3224MHz iSatellite Fiber Link, iGPON kunye neGPON +, i-EoC, i-1218MHz i-CATV ye-transmitter ebonakalayo kunye ne-node optical, iklasi yokusasaza i-AV / ASI / SDI ikhonkco yefiber.
