TETRA Fiber Optical repeaters ni ninu Titunto si Unit (MU) ati Latọna jijin Unit (RU).Ọkan Titunto si Unit le ṣiṣẹ pọ pẹlu 1 to 4 Latọna Unit.Ẹka Titunto n gbe ifihan BTS sinu ifihan agbara opiti ati gbe ifihan agbara opitika si Ẹka Latọna jijin (RU).Ẹka Latọna jijin (RU) gbe ifihan agbara opitika sinu ifihan RF, mu ifihan RF pọ si ati bo awọn agbegbe ibi-afẹde.
Ẹya latọna jijin opiti (RU) ti sopọ si ẹyọ titun nipasẹ okun opiti.Awọn ifihan agbara BTS ti wa ni wiwo si ẹyọkan titunto si fun iyipada itanna / opiti.Awọn ifihan agbara iyipada wọnyi jẹ gbigbe nipasẹ okun opiti si awọn ẹya latọna jijin ati nikẹhin si eriali.Nipa lilo awọn kebulu okun opiti, awọn adanu attenuation giga lori awọn kebulu coaxial gigun ni a yago fun.
Eyi pọ si aaye ti o pọju laarin ẹyọ latọna jijin ati ẹyọ titunto si 20 km.A ṣe ifunni subcarrier sinu ọna ifihan agbara lori okun opiti lati ṣiṣẹ bi iṣakoso latọna jijin ati ikanni abojuto fun gbogbo ohun elo.Nitori ero modular nigbamii imugboroosi ati igbesoke ṣee ṣe.Atunṣe eto tun le pese ni ipa idiyele kekere.
• Imudara sẹẹli inu ile ti o munadoko
• Fifi sori ẹrọ ti o rọrun nitori awọn iwọn kekere ati iṣẹ-ṣiṣe ere-laifọwọyi
• Igbẹkẹle giga
Awọn oluṣe atunṣe okun-okun fun awọn ọna redio ọna meji.Ojutu okun opitika fun agbegbe inu ile ati itẹsiwaju ibiti o wa ni VHF, UHF ati awọn igbohunsafẹfẹ TETRA.
Eto eriali ti a pin kaakiri (DAS) fun agbegbe redio alailowaya inu ile.
Awọn ohun elo ti o wọpọ:
TETRA Fiber Optical Repeaters ti wa ni lilo ni akọkọ ni agbegbe inu ile ati awọn agbegbe ita tẹlẹ pẹlu awọn okun opiki.Ohun elo ti Tetra Fiber Optical repeaters yoo ni imunadoko imukuro awọn agbegbe afọju ifihan agbara, mu didara nẹtiwọọki pọ si, mu aworan ti awọn oniṣẹ cellular dara si ati mu wọn ni ere diẹ sii.Wọn ni lilo pupọ ni awọn aaye isalẹ.
