Tlhaloso ea Sehlahisoa
TETRA-cable-access MDAS Fiber Optic Repeater e sebelisetsoa ho holisa pontšo ea thepa ea TETRA.The Master Optical Unit System e tšoara letšoao la BTS la TETRA ebe e e fetola letšoao la optic ebe e fetisetsa letšoao le matlafalitsoeng ho Remote Optical Unit ka lithapo tsa fiber optic.Setsi sa Remote Optical se tla fetola letšoao la optic ho letšoao la TETRA ebe se fetola Downlink Amplifier 'me se fane ka letšoao libakeng tseo ho tsona mosebetsi oa marang-rang o sa lekaneng.
'Me lets'oao la mohala le lona le holisitsoe mme le fetisetsoa ho BTS ka tsela e fapaneng.Sistimi ea kabo ea khamphani ea rona ea lipatlisiso le nts'etsopele e ikemetseng e entsoe ke Master Optical Unit le Remote Optical Unit.Mojule oa ka hare o kopantsoe, theknoloji e kopantsoeng haholo ke ho ntlafatsa botsitso ba lisebelisoa.
