Agasti 2, 2022, iGreatway Technology yamemezela ukukhulula i-GLB3500M-6 modular 6ch RF ngaphezulu kwesidlulisi sefayibha esisodwa nomamukeli.I-GLB3500M-6 inobude obungamaza obuyi-6ch CWDM ngaphezu kwefayibha eyodwa ye-SM ukuya kwesamukeli esisodwa noma eziningi zamehlo, lapho ubude beza beza be-CWDM buphethe i-wideband engu-174MHz~2350MHz, okuhlanganisa i-Terrestrial TV 174~806MHz noma 950~2150MHz noma inhlanganisela ye-Terr TV ne-Saint RF enhle kakhulu. Ikhwalithi yesiginali ye-RF nokuhlukaniswa phakathi kwamasignali e-RF.
Uma kuqhathaniswa nesethelayithi i-RF phezu kwentambo ye-coaxial kuya ku-TV Headend, i-GLB3500M-6 inezinzuzo ezintathu: 1. Ubukhulu obungu-6 be-antenna RFs phezu kwe-SM fiber eyodwa ukuya ehhovisi le-Headend kanye nebanga elide kakhulu ukusuka kumamitha ayi-100 ukuya ku-10Km;2. Ukuvikelwa kokukhanyisa ezintweni ze-Headhead ngenxa yekhebula le-fibre elingaqhubeki;3. Ukuhlukaniswa okuphansi phakathi kwezindawo zeSatellite dish kanye nendawo yemishini ye-Headend.
I-GLB3500M-6 iphinde inikeze ukuguquguquka kwesistimu ye-SMATV (Satellite Master Antenna TV).Ukunikezwa kwamandla kwe-DC okubuyela emuva ku-LNB kungaba yinoma yimaphi amandla we-13V, 18V, 13V 22KHz, 18V 22KHz noma ungabi namandla e-DC, asethwe kuqala efekthri.
I-GLB3500M-6 ingaletha amasiginali we-RF wamasathelayithi angu-6 aphezulu noma okuqukethwe okugcwele kwamasathelayithi angu-3 ngefayibha eyodwa eya ezakhiweni ezengeziwe nababhalisile ebangeni le-fiber engaba ngu-5Km.Ihlangene ne-PLC fibre splitter kanye ne-cascading multiswitch esakhiweni ngasinye, i-GLB3500M-6 ingasabalalisa ama-RF antenna amasathelayithi amaningi kanye ne-Terr TV enanini lababhalisile emphakathini.
Isixhumanisi se-GLB3500M-6 se-fiber sihlanganisa i-GLB3500M-6T i-optical transmitter kanye ne-GLB3500M-6R yokwamukela optical.Ngama-laser/photodiode e-CWDM kanye nesekhethi yokulawula inzuzo ye-RF yomsindo ophansi, i-GLB3500M-6T eyodwa ingaletha i-RF yekhwalithi ephezulu iye kuma-32 GLB3500M-6R aphezulu ezamukeli ezibonakalayo.
Itholakala e-Shenzhen, i-Greatway Technology iyi-RF phezu kwe-fiber transmission product design house kanye nefekthri kusukela ngo-2004, ihlinzeka ngesamukeli se-FTTH CATV, i-RFoG ONU yemodemu yekhebula le-ftth, isathelayithi eyodwa/I-Twin/Quatro LNB RF phezu kwe-GPON, amasathelayithi Amabili/Ane phezu kwefayibha eyodwa. isixhumanisi, 3224MHz Satellite Fiber Link, GPON kanye GPON+, EoC, 1218MHz CATV optical transmitter kanye node optical, isigaba sokusakaza AV/ASI/SDI isixhumanisi fiber.
