GLB3500MT Terr TV le Sat Fiber Optic Transmitter
Tlhaloso ea Sehlahisoa
GLB3500M ke modular 45 ~ 2600MHz RF holim'a sehokelo sa fiber, e fetisang likanale tsa Terrestrial TV le L-Band RF e le 'ngoe holim'a fiber e le' ngoe.
Direct Broadcasting Satellite (DBS) le Direct to Home (DTH) ke mekhoa e tsebahalang haholo ea ho natefeloa ke TV ea sathelaete lefatšeng ka bophara.Ho e etsa, satellite antenna, coaxial cable, splitter kapa multi-switcher le satellite receiver lia hlokahala.Leha ho le joalo, ho kenya antenna ea sathelaete ho ka ba thata ho ba ngolisitseng ba lulang lifoleteng.SMATV (satellite mater antenna TV) ke tharollo e ntle bakeng sa batho ba lulang mohahong kapa sechabeng ho arolelana sejana se le seng sa satellite le antenna ea lefatše.Ka thapo ea faeba, lets'oao la SMATV RF le ka fetisetsoa ho 30Km hole kapa la ajoa lifoleteng tse 32 ka kotloloho, ho 320 kapa 3200 kapa 32000 foleteng ka GWA3530 fiber optic amplifier.
GLB3500M e na le module ea GLB3500MT transmitter le GLB3500MR ea moamoheli.Mojule oa transmitter oa GLB3500MT o na le kou e le 'ngoe kapa tse peli tsa RF ha GLB3500MR e na le boema-kepe bo le bong ba tlhahiso ea RF.E nang le linearity e phahameng ea 1550nm e sa pholileng ea DFB laser, photodiode le lerata le tlaase la RF e fumana taolo ea potoloho, GLB3500MT e ka fana ka liteishene tsa boleng bo holimo tsa Terrestrial TV le satellite RF holim'a fiber ho ba ngolisitseng ba seng bakae ka ho toba kapa likete tsa ba ngolisitseng FTTH ka EDFA.Ka khetho ea 1310nm/1490nm/1550nm WDM, GLB3500M e ka kenya L-Band+TV RF holim'a GPON/GEPON.Ntle le mofuta oa modular, GLB3500M e ka ba le mofuta oa 19”1RU ha o e kopa.Fiber ho mofuta oa ntlo ea polasetiki ea lehae ea GLB3500MR ke GFH2000 optical LNB, moo morekisi oa FTTH a hlokang feela fiber e le 'ngoe le ho hlahisa matšoao a sathelaete likamoreng tse' maloa ka lapeng.
Likarolo tse ling:
• Mohaho o tiileng oa aluminium die cast.
• Kenyeletso e le 'ngoe e kopaneng ea RF e nang le bandwidth:45~2600MHz kapa.
• Lisebelisoa tse peli tse arohaneng tsa RF, ho kenyelletsa:
-Tlhahiso e le 'ngoe ea TV ea Lefatše, bandwidth: 174 -806 MHz.
-E 'ngoe ea LNB RF keno, bandwidth: 950MHz ~ 2150MHz (13V kapa 18V DC kgetho bakeng sa LNB ka kopo).
• Kou e le 'ngoe ea tlhahiso ea RF.
• High Linearity 1550nm e sa pholileng DFB Laser le Photodiode.
• Lerata le tlaase la RF Gain Control circuit.
