Nyamavhuvhu 2, 2022, Greatway Technology yakazivisa kuburitsa GLB3500M-6 modular 6ch RF pamusoro peimwe fiber transmitter uye inogamuchira. GLB3500M-6 ine 6ch CWDM wavelengths pamusoro peimwe SM faibha kune imwe kana akawanda optical inogamuchira, uko yega yega CWDM wavelength inotakura wideband 174MHz ~ 2350MHz, kusanganisira Terrestrial TV 174 ~ 806MHz kana 950 ~ 2150MHz kana musanganiswa weTerr TV neSabata yakanakisa. RF chiratidzo chemhando uye kuparadzaniswa pakati pezviratidzo zveRF.
Kuenzaniswa nesetiraiti RF pamusoro pecoaxial tambo kuTV Headend, GLB3500M-6 ine zvakanakira zvitatu: 1. Maximum 6 setiraiti antenna RFs pamusoro peimwe SM fiber kuenda kuHeadend hofisi uye kureba kureba kubva 100 metres kusvika 10Km; 2. Kudzivirirwa kwemwenje kune Headhead zvishandiso nekuda kweiyo isiri-conductive fiber tambo; 3. Grounding yekuzviparadzanisa pakati peSatellite dish nzvimbo uye Headend midziyo nzvimbo.
GLB3500M-6 inopawo kuchinjika kweSMATV (Satellite Master Antenna TV) system. Iri reverse DC magetsi ekupa LNB anogona kuva chero e13V, 18V, 13V 22KHz, 18V 22KHz kana pasina DC simba, preset pafekitori.
GLB3500M-6 inogona kuburitsa masaini matanhatu setiraiti antennas RF masiginecha kana izvo zvizere zviri mukati 3 setiraiti pamusoro pe fiber imwe kune zvimwe zvivakwa uye vanyoreri mu5Km radius fibre kureba. Pamwe chete nePLC fiber splitter uye cascading multiswitchs muchivako chimwe nechimwe, GLB3500M-6 inogona kugovera akawanda setiraiti antenna RFs uye Terr TV kune vakati wandei vanyoresa munharaunda.
GLB3500M-6 fiber link inosanganisira GLB3500M-6T optical transmitter uye GLB3500M-6R inogamuchira yemaziso. Iine CWDM lasers/photodiode uye yakaderera ruzha RF kuwana kudzora dunhu, imwe GLB3500M-6T inogona kuendesa yakakwira mhando RF kusvika pakakwirira 32 GLB3500M-6R inogamuchira vanogamuchira.
Iri muShenzhen, Greatway Technology ndeye RF pamusoro pe fiber transmission chigadzirwa dhizaini imba uye fekitori kubvira 2004, ichipa FTTH CATV inogamuchira, RFoG ONU yeftth cable modem, satellite single/Twin/Quatro LNB RF pamusoro peGPON, Maviri/Mana satellite pamusoro pefiber imwe. link, 3224MHz Satellite Fiber Link, GPON uye GPON+, EoC, 1218MHz CATV optical transmitter uye optical node, kirasi yekutepfenyura AV/ASI/SDI fiber link.
