Sisitemu ya Fibre Optic Cellular Repeaters (FOR) yashizweho kugirango ikemure ibibazo byikimenyetso kigendanwa kigendanwa ahantu hatari kure ya BTS (Base Transceiver Station) kandi ifite umuyoboro wa fibre optique munsi yubutaka.
Gukemura ahantu hose bigoye kugera!
Sisitemu YOSE igizwe nibice bibiri: Igice cyabaterankunga nigice cya kure.Batanga mu mucyo no kongera ibimenyetso bidafite umugozi hagati ya BTS (Base Transceiver Station) na mobile ukoresheje insinga za fibre optique.
Igice cy'Abaterankunga gifata ibimenyetso bya BTS binyuze kuri kuperi itaziguye ifunze BTS (cyangwa binyuze mu kirere cyoherejwe na RF binyuze muri Donor Antenna), hanyuma ikayihindura mu kimenyetso cya optique kandi ikohereza ibimenyetso byongerewe imbaraga mu gice cya kure ikoresheje insinga za fibre optique.Igice cya kure kizongera guhindura ibimenyetso bya optique mubimenyetso bya RF kandi bitange ibimenyetso mubice aho imiyoboro idahwitse.Kandi ibimenyetso bigendanwa nabyo byongerewe kandi bisubizwa muri BTS binyuze muburyo bunyuranye.
KingtoneFibre Optic GusubiramoSisitemu yashizweho kugirango ikemure ibibazo byintege nke zigendanwa, bihendutse cyane kuruta gushiraho Sitasiyo nshya (BTS).Igikorwa nyamukuru cya sisitemu ya RF Repeaters: Kumurongo wamanutse, ibimenyetso biva muri BTS bihabwa abaterankunga (DOU), DOU noneho igahindura ibimenyetso bya RF mukimenyetso cya laser hanyuma igaburira fibre kugirango yohereze muri Remote Unit (ROU).RU noneho ihindure ibimenyetso bya laser kubimenyetso bya RF, hanyuma ukoreshe Power Amplifier kugirango wongere imbaraga nyinshi kuri IBS cyangwa antenne yo gukwirakwiza.Kuburyo bwo hejuru, Nibikorwa bihinduka, ibimenyetso biva kubakoresha mobile bigaburirwa ku cyambu cya MS cya DOU.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 DOU, ibimenyetso bya laser biva muri ROU bihindurwamo ibimenyetso bya RF na transitike ya RF optique.Noneho ibimenyetso bya RF byongerewe ibimenyetso byinshi byingufu bihabwa BTS.
Ibiranga
- Igikoresho cya aluminium-alloy gifite imbaraga nyinshi zo kurwanya umukungugu, amazi no kubora;
- Omni-icyerekezo cyo gukwirakwiza antenne irashobora gukoreshwa kugirango yagure byinshi;
- Kwemeza WDM (Wavelength Division Multiplexing) module kugirango tumenye intera ndende;
- Ubwiza bwogukwirakwiza ibimenyetso bihamye kandi bunoze;
- Igice kimwe cyabaterankunga kirashobora gushyigikira Unite zigera kuri 4 kugirango ukoreshe cyane umugozi wa fibre optique;
- Icyambu cya RS-232 gitanga amahuza ku ikaye kugirango igenzurwe n’ibanze ndetse na modem yubatswe mu buryo butemewe kugira ngo ivugane na NMS (Sisitemu yo gucunga imiyoboro) ishobora kugenzura kure imikorere y’abasubiramo no gukuramo ibipimo ngenderwaho kuri repetater.
