Kí nìdí Fiber Optic Repeater?
Kingtone Fiber Optic Repeaters eto jẹ apẹrẹ lati yanju awọn iṣoro ti ifihan agbara alagbeka alailagbara, eyiti o din owo pupọ ju iṣeto ipilẹ Ibusọ tuntun (BTS).Iṣe akọkọ ti eto RF Repeaters: Fun ọna asopọ isalẹ, awọn ifihan agbara lati BTS jẹ ifunni si Ẹka Titunto (MU), MU lẹhinna yi ifihan RF pada si ifihan laser lẹhinna ifunni si okun lati tan kaakiri si Ẹka Latọna jijin (RU).RU lẹhinna yi ifihan agbara laser pada si ifihan agbara RF, ati lo Ampilifaya Agbara lati pọ si agbara giga si IBS tabi eriali agbegbe.Fun ọna asopọ oke, Ṣe ilana iyipada, awọn ifihan agbara lati alagbeka olumulo jẹ ifunni si ibudo MS MU.Nipasẹ duplexer, ifihan agbara ti pọ nipasẹ ampilifaya ariwo kekere lati mu agbara ifihan dara si.Lẹhinna awọn ifihan agbara jẹ ifunni si module opitika fiber RF lẹhinna yipada si awọn ifihan agbara laser, lẹhinna ifihan agbara laser ti gbejade si MU, ifihan agbara laser lati RU yipada si ifihan RF nipasẹ transceiver opiti RF.Lẹhinna awọn ifihan agbara RF ti pọ si awọn ifihan agbara diẹ sii ti a jẹ si BTS.
Awọn ẹya:
- Fiber Optic RF Repeater jẹ ojutu igbẹkẹle lati faagun ati ilọsiwaju agbegbe agbegbe ti nẹtiwọọki TETRA 400MHz
- Ni awọn modulu akọkọ meji, Titunto si ati awọn ẹya Ẹrú pupọ.
- 33, 37, 40 tabi 43dBm agbara iṣelọpọ akojọpọ, pade awọn iṣedede awọn eto
- Fifi sori aaye ti o rọrun ati itọju dinku yiyọ ati awọn idiyele iṣẹ
- Gbigbe ifihan agbara ni oluyipada okun opitiki ko ni idamu nipasẹ awọn ipa ita
- Pese iṣẹ agbegbe RF iyara pupọ si Ibusọ Ipilẹ TETRA rẹ
- Iwọn Iwapọ ati Iṣe to gaju ni apade ti ko ni omi ti o dara fun awọn fifi sori ita ati inu ile
