TETRA Fiber Optical repeaters e na le Master Unit (MU) le Remote Unit (RU).Setsi se le seng sa Master se ka sebetsa 'moho le 1 ho isa ho tse 4 tsa Remote Units.Master Unit e fetisetsa lets'oao la BTS ho lets'oao la optical mme e fetisetsa lets'oao la optical ho Remote Unit (RU).Setsi sa Remote (RU) se fetisetsa lets'oao la optical ho lets'oao la RF, ho holisa lets'oao la RF le ho koahela libaka tse shebiloeng.
Optical remote unit (RU) e hokahane le yuniti e kholo ka fiber optical.Lipontšo tsa BTS li hokahantsoe le yuniti e kholo bakeng sa phetoho ea motlakase / optical.Lipontšo tsena tse fetotsoeng li fetisoa ka fiber ea optical ho ea ho li-unit tse hole mme qetellong ho antenna.Ka ho sebelisa likhoele tsa optical fiber, tahlehelo e phahameng ea ho thella mehala e telele ea coaxial e qojoa.
Sena se eketsa sebaka se ka bang teng lipakeng tsa yuniti e hole le unit unit ho fihla ho 20 km.Subcarrier e kenngoa ka har'a tsela ea matšoao ho fiber ea optical ho sebetsa e le mocha o laolang le ho laola lisebelisoa tsohle.Ka lebaka la mohopolo oa modular hamorao ho atolosoa le ho ntlafatsa hoa khoneha.Khaello ea mesebetsi ea tsamaiso e ka boela ea fanoa ka litšenyehelo tse tlaase.
• Sehlahisoa se bolokang chelete ka tlung se ntlafatsang lisele
• Ho kenya habonolo ka lebaka la litekanyo tse nyane le ts'ebetso ea ho iphumanela chelete
• Ho tšepahala ho phahameng
Li-repeater tse feptjoang ka fiber bakeng sa litsamaiso tsa radio tsa litsela tse peli.Tharollo ea fiber ea optical bakeng sa tšireletso ea ka tlung le katoloso ea mefuta ho maqhubu a VHF, UHF le TETRA.
Moralo ona o abile sistimi ea li-antenna (DAS) bakeng sa khaso ea radio e se nang mohala.
Lisebelisoa tse Tloaelehileng:
TETRA Fiber Optical Repeaters e sebelisoa haholo-holo sebakeng se ka hare le libakeng tse ka ntle tse seng li na le likhoele tsa optic.Tšebeliso ea li-repeaters tsa Tetra Fiber Optical e tla felisa ka katleho libaka tse foufetseng tsa pontšo, ho ntlafatsa boleng ba marang-rang, ho ntlafatsa setšoantšo sa basebetsi ba cellular le ho ba tlisetsa phaello e ngata.Li sebelisoa haholo libakeng tse ka tlase.
