GLB3500MT Terr TV a me Sat Fiber Optic Transmitter
Hōʻike huahana
ʻO GLB3500M kahi modular 45 ~ 2600MHz RF ma luna o ka loulou fiber, e hoʻouna ana i nā kahawai TV Terrestrial a me hoʻokahi L-Band RF ma luna o hoʻokahi fiber.
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.
Aia ka GLB3500M me GLB3500MT transmitter module a me GLB3500MR receiver module. Loaʻa i ka module transmitter GLB3500MT hoʻokahi a ʻelua paha mau awa hoʻokomo RF aʻo GLB3500MR hoʻokahi puka puka RF. Me ka laina kiʻekiʻe 1550nm uncooled DFB laser, photodiode a me ka haʻahaʻa haʻahaʻa RF loaʻa ka mana kaapuni, hiki iā GLB3500MT ke hāʻawi i nā kaha TV Terrestrial kiʻekiʻe a me ka satellite RF ma luna o ka fiber i kekahi mau mea kākau pololei a i ʻole mau tausani o nā mea kākau FTTH ma o EDFA. Me 1310nm / 1490nm / 1550nm WDM koho, GLB3500M hiki ke hoʻokomo i ka L-Band + TV RF ma luna o GPON / GEPON. Ma waho aʻe o ka mana modular, hiki iā GLB3500M ke loaʻa i ka mana 19"1RU ma ke noi. ʻO ka fiber i ka mana o ka hale plastic home o GLB3500MR ʻo GFH2000 optical LNB, kahi e pono ai ka mea kākau inoa FTTH i hoʻokahi fiber i loko a hoʻopuka i nā hōʻailona satellite i kekahi mau lumi o ka ʻohana.
Nā hiʻohiʻona ʻē aʻe:
• ka hale make alumini paʻa.
• Hoʻokahi hoʻokomo RF hui pū me ka bandwidth: 45 ~ 2600MHz a i ʻole.
• ʻElua mea hoʻokomo RF kaʻawale, me:
-Hoʻokahi hoʻokomo TV Terrestrial, bandwidth: 174 -806 MHz.
-Hoʻokahi LNB RF hoʻokomo, bandwidth: 950MHz ~ 2150MHz (13V a i ʻole 18V DC koho no LNB ma ke noi).
• Hoʻokahi puka puka RF.
• High Linearity 1550nm uncooled DFB Laser a Photodiode.
• ka leo haʻahaʻa RF Gain Control circuit.
