Kungani i-Fiber Optic Repeater?
Uhlelo lwe-Kingtone Fiber Optic Repeaters luklanyelwe ukuxazulula izinkinga zesignali yeselula ebuthakathaka, eshibhe kakhulu kunokusethwa kwe-Base Station entsha (BTS).Ukusebenza okuyinhloko kohlelo lwe-RF Repeaters: Ukuze uthole isixhumanisi esiphansi, amasignali asuka ku-BTS aphakelwa ku-Master Unit(MU), i-MU bese iguqula isignali ye-RF ibe isignali ye-laser bese iphakela ku-fiber ukuze idluliselwe ku-Remote Unit(RU).I-RU bese iguqula isignali ye-laser ibe isignali ye-RF, futhi isebenzisa Isihlelamandla ukuze ikhulise amandla aphezulu ku-IBS noma i-antenna yokumboza.Ukuze uthole isixhumanisi saphezulu, Ingabe inqubo yokuhlehla, amasiginali asuka kumakhalekhukhwini womsebenzisi anikezwa echwebeni le-MU le-MS.Nge-duplexer, isignali ikhuliswa isikhulisi somsindo ophansi ukuze kuthuthukiswe amandla esignali.Bese amasiginali anikezwa i-RF fibre optical module bese iguqulelwa kumasiginali ye-laser, bese isiginali ye-laser idluliselwa ku-MU, isiginali ye-laser esuka ku-RU iguqulelwa kusiginali ye-RF nge-RF optical transceiver.Bese amasiginali e-RF akhuliswa abe amasiginali wamandla engeziwe anikezwa i-BTS.
Izici:
- I-Fiber Optic RF Repeater iyisixazululo esithembekile sokunweba nokuthuthukisa indawo ehlanganisa inethiwekhi ye-TETRA 400MHz.
- Iqukethe amamojula amabili ayinhloko, i-Master kanye namayunithi amaningi e-Slave.
- 33, 37, 40 noma 43dBm amandla aphumayo ayinhlanganisela, ahlangabezana nezindinganiso zesistimu
- Ukufakwa kalula kwenkambu nokunakekela kunciphisa izindleko zokuphuma nezokusebenza
- Ukudluliswa kwesignali ku-fiber optic repeater akuphazanyiswa amathonya angaphandle
- Nikeza insizakalo esheshayo ye-RF ku-TETRA Base-Station yakho
- Usayizi Ohlangene kanye Nokusebenza Okuphezulu endaweni ebiyelwe engangeni manzi efanele ukufakwa ngaphandle nangaphakathi
