TETRA Fiber Optical inodzokorora inosanganisira Master Unit (MU) uye Remote Unit (RU).Imwe Master Unit inogona kushanda pamwe chete ne1 kusvika ku4 Remote Units.Iyo Master Unit inotamisa chiratidzo cheBTS muchiratidzo chemaziso uye inotumira chiratidzo chemaziso kune Remote Unit (RU).Iyo Remote Unit (RU) inoendesa chiratidzo chechiratidzo muRF chiratidzo, kusimudzira chiratidzo cheRF uye kuvhara nzvimbo dzakatariswa.
Iyo optical remote unit (RU) yakabatana kune master unit kuburikidza neoptical fiber.Iwo masaini eBTS anosanganisirwa kune master unit yemagetsi / optical shanduko.Aya masaini akashandurwa anofambiswa kuburikidza neoptical fiber kumayuniti ari kure uye pakupedzisira kune antenna.Nekushandisa tambo dzefiber optical, kurasikirwa kwakanyanya kweattenuation patambo refu dzecoaxial kunodzivirirwa.
Izvi zvinowedzera chinhambwe chinogona pakati pekure kure unit uye master unit kusvika ku20 km.A subcarrier inodyiswa munzira yechiratidzo pane optical fiber kuti iite senge kure kure uye yekutarisa chiteshi kune ese maturusi.Nekuda kweiyo modular pfungwa gare gare kuwedzera uye kusimudzira kunogoneka.System redundancy inogonawo kupihwa nemutengo wakaderera.
• Inodhura-inoshanda indoor cell enhancer
• Kuiswa nyore nekuda kwezviyero zviduku uye auto-kuwana kushanda
• Kuvimbika kwepamusoro
Fibre-yakadyiswa inodzokorora yenzira mbiri redhiyo masisitimu.Optical fiber mhinduro yekuvhara yemukati uye huwandu hwekuwedzera muVHF, UHF uye TETRA frequency.
Iyi dhizaini yakagovera antenna system (DAS) yekuvaka isina waya yekuvhara.
Zvakajairika Zvishandiso:
TETRA Fiber Optical Repeaters inonyanya kushandiswa munzvimbo yemukati uye yekunze nzvimbo dzatova neoptic fibers.Iko kushandiswa kweTetra Fiber Optical inodzokorora inobvisa zvinobudirira nzvimbo dzemapofu, kusimudzira mhando yetiweki, kunatsiridza mufananidzo wevanoshandisa cellular uye kuunza purofiti yakawanda.Iyo inoshandiswa zvakanyanya munzvimbo dziri pazasi.
