GLB3500E-4R Nilesat ndi Arabsat pazingwe ziwiri kunyumba imodzi

Mawonekedwe:

Nilesat wideband LNB yonyamulidwa ndi fiber 1 GLB3500E-2T transmitter.

Arabsat wideband LNB yonyamulidwa ndi fiber 2 GLB3500E-2T transmitter.

GLB3500E-4R ili ndi zolowetsa ziwiri za SC/APC ndi RF imodzi.

Kuwala kwa AGC: -6dBm ~ +1dBm.

Zotulutsa za Sat RF: 1210MHz, 1420MHz, 1680MHz, 2040MHz.

Doko limodzi la SatCR RF lofikira mpaka 4 olandila osavomerezeka.

Zogwirizana ndi EN50494 + EN50607 miyezo.

Zosankha: Madoko awiri a SatCR RF mpaka 8 osalandira olandila.

Posankha doko la WDM kupita ku GPON ONU.


PRODUCT DETAIL

Mafotokozedwe Akatundu

GLB3500E-4R satellite TV FTTH Optical LNB ndi cholandirira chamitundu iwiri cha fiber optic, chosinthira ma RF anayi otambalala kuchokera ku ma satelayiti awiri (monga, Nilesat ndi Arabsat) pa siginecha ya CHIKWANGWANI kukhala imodzi yotulutsa RF mpaka zolandila satellite zinayi mnyumba imodzi. Kugwira ntchito ndi 2pcs Greatway GLB3500E-2T satellite TV optical transmitters kuchokera pazolowetsa ziwiri za fiber, GLB3500E-4R yamanga-module ya SatCR yosinthira RF yotambalala kuchokera ku ma satelayiti awiri, imatulutsa magulu 4 ogwiritsira ntchito satellite padoko limodzi la SatCR RF kwa 4 olandila satana.

SMATV (Satellite Master Antenna TV) ndiyotchuka popereka TV yapa satellite ndi TV yapadziko lapansi kwa olembetsa omwe amakhala m'nyumba kapena mdera. Traditional SMATV imatha kugawa zomwe zili mu mlongoti kudzera pa multiswitch kupita ku zolandila satana pa chingwe cha coaxial. Chifukwa chakutayika kwakukulu pama frequency apamwamba a satellite, mtunda wa chingwe cha SMATV ndi wosakwana mita 150 ngakhale ndi amplifier ya IF pa intaneti. Ma satelayiti awiri odziwika bwino a SMATV amafunikira zingwe 9 za RF kuchokera padenga la nyumba kupita kumalo osinthika ambiri, omwe amatumikira olembetsa osakwana 100 mnyumba imodzi. Kwa ma satellites awiri a SMATV pa fiber, Greatway Technology ili ndi GLB3500M-8 monga yankho la FTTB ndi GLB3500E-4R monga yankho la FTTH. Yankho la FTTB liyenera kukhala ndi satellite STB nthawi zonse, pomwe yankho la FTTH liyenera kukhala ndi satana STB yothandizira unicable.

GLB3500E-4R ili ndi 1310nm/1490nm/1550nm WDM njira yolumikizira kuti mugwire ntchito limodzi ndi GPON ONU mu pulogalamu iliyonse ya FTTH, yomwe imathandiza kuti zonse za satellite LNB ziziyikidwa mu GPON system.

Zina:

Nyumba zapulasitiki zolimba.

Zolowetsa ziwiri za SC/APC ndi kutulutsa kumodzi kwa RF.

High Linearity Photodiode.

Kuwala kwa AGC: -6dBm ~ +1dBm.

Doko limodzi la SatCR RF lofikira mpaka 4 olandila osavomerezeka.

Sat RF Band: 950 ~ 2150MHz.

Padziko Lapansi TV RF Bandwidth: 88~250MHz.

Zogwirizana ndi EN50494 + EN50607 miyezo.

Posankha doko la WDM kupita ku GPON ONU.

Zosankha: Doko limodzi la SatCR RF mpaka 8 olandila osavomerezeka.
