GFD2000 LNB Dongle

ʻO GFD2000 fiber optic LNB Dongle kahi mea hoʻokipa TV fiber optic i hoʻokomo ʻia ma ke awa RF o satellite STB. Ke hana nei me Greatway GLB3500MT optical transmitter, GFD2000 LNB dongle hoʻololi i ka hōʻailona optical i Satellite RF. Hoʻohana ʻia e ka 13V/18V DC mai ka mea hoʻokipa ukali, hoʻopuka ʻo GFD2000 i nā transponder satellite kiʻekiʻe ma o ka loaʻa ʻana o ka hoʻolālā palahalaha. Loaʻa iā GFD2000 ka satellite MER maikaʻi loa ma ka mana hoʻokomo optical haʻahaʻa loa (e like me -18dBm).

ʻO Direct Broadcasting Satellite (DBS) a me Direct to Home (DTH) ke ala kaulana loa e leʻaleʻa i ka TV satelite a puni ka honua. No ka hana ʻana, pono nā antenna satellite, coaxial cable, splitter a i ʻole multi-switcher a me ka mea lawe ukali. Eia naʻe, paʻakikī paha ka hoʻokomo ʻana i nā antenna satellite i ka poʻe kākau inoa e noho ana ma nā hale. ʻO SMATV (satellite mater antenna TV) kahi hopena maikaʻi no ka poʻe e noho ana i ka hale a i ʻole ke kaiāulu e kaʻana like i hoʻokahi kīʻaha ukali a me ka antenna TV terrestrial. Me ka fiber cable, hiki ke hāʻawi ʻia ka hōʻailona SMATV RF i 30Km mamao a hāʻawi ʻia i nā hale 32 pololei, i 320 a i ʻole 3200 a i ʻole 32000 mau hale ma o GWA3530 fiber optic amplifier.

Hiki iā GLB3500MT ke hoʻololi i ka 32UB kiʻekiʻe loa mai hoʻokahi ukali a i ʻole ʻehā mau satellite i 1550nm fiber ma o ka mea hoʻololi ukali waho. 20dBm mana kiʻekiʻe mana GLB3500MT-D20 hiki ke hoʻokele pololei i 512pcs GFD2000 LNB Dongles. Hāʻawi kēia i kahi ala kūpono no ka poʻe kākau inoa e noho ana ma nā hale a i ʻole ke kaiāulu e nānā i nā mea kaulana e like me BeIN, OSN etc. ma luna o ka STB noho mau a i ʻole ka decoder noho i koho ʻia ma ke kau ʻana i kahi dongle LNB ma kāna awa RF. Ma muli o ka kānana 1550nm i kūkulu ʻia, hiki ke hoʻokomo ʻia ʻo GFD2000 ma ka sat decoder RF port pololei ʻoiai inā ʻaʻohe GPON / XGPON ONU ka mea kākau.
