Kuki Fibre Optic Gusubiramo?
Sisitemu ya Kingtone Fibre Optic Repeaters yateguwe kugirango ikemure ibibazo byikimenyetso kigendanwa kidakomeye, kikaba gihendutse cyane kuruta gushiraho Sitasiyo nshya (BTS).Igikorwa nyamukuru cya sisitemu ya RF isubiramo: Kumurongo wamanutse, ibimenyetso biva muri BTS bihabwa Master Unit (MU), MU noneho ihindura ibimenyetso bya RF kuri signal ya laser hanyuma igaburira fibre kugirango yohereze muri Remote Unit (RU).RU noneho ihindure ibimenyetso bya laser kubimenyetso bya RF, hanyuma ukoreshe Power Amplifier kugirango wongere imbaraga nyinshi kuri IBS cyangwa antenne yo gukwirakwiza.Kuri up up ihuza, Nibikorwa bisubira inyuma, ibimenyetso biva kubakoresha mobile bigaburirwa ku cyambu cya MS.Binyuze kuri duplexer, ibimenyetso byongerwaho amajwi make yongerera imbaraga imbaraga kugirango ibimenyetso byongere imbaraga.Noneho ibimenyetso bigaburirwa kuri fibre optique ya RF fibre hanyuma igahinduka mubimenyetso bya laser, hanyuma ibimenyetso bya laser byoherezwa muri MU, ibimenyetso bya laser biva muri RU bihinduka mubimenyetso bya RF na trans optique ya RF optique.Noneho ibimenyetso bya RF byongerewe ibimenyetso byinshi byingufu bihabwa BTS.
Ibiranga:
- Fibre Optic RF Repeater nigisubizo cyizewe cyo kwagura no kunoza aho ikwirakwizwa rya TETRA 400MHz
- Igizwe nuburyo bubiri bwingenzi, Umwigisha hamwe nibice byinshi byabacakara.
- 33, 37, 40 cyangwa 43dBm ikomatanya imbaraga zisohoka, zujuje ubuziranenge bwa sisitemu
- Kwubaka umurima byoroshye no kubungabunga bigabanya ibiciro no gukora
- Ihererekanyabubasha muri fibre optique risubirwamo ntabwo rihungabanywa ningaruka zo hanze
- Tanga serivisi yihuse ya RF kuri TETRA Base-Sitasiyo
- Ingano yuzuye hamwe nubushobozi buhanitse mukuzitira amazi adakwiriye hanze no murugo
