Abaphindayo be-TETRA Fiber Optical bahlanganisa i-Master Unit (MU) kanye ne-Remote Unit (RU).Iyunithi Eyingcweti eyodwa ingasebenza kanye neyunithi eyi-1 kuya kwezi-4 ezikude.I-Master Unit idlulisela isignali ye-BTS kusignali yokubona futhi idlulisele isignali yokubona ku-Remote Unit (RU).I-Remote Unit (RU) idlulisela isignali yokubona kusiginali ye-RF, ikhulise isignali ye-RF futhi imboze izindawo eziqondiwe.
Iyunithi elikude le-optical (RU) lixhunywe kuyunithi eyinhloko nge-fiber optical.Amasignali e-BTS axhunywe kuyunithi eyinhloko yokuguqulwa kukagesi/okubonwayo.Lezi zimpawu eziguquliwe zidluliselwa nge-optical fiber kumayunithi akude futhi ekugcineni ziye othini.Ngokusebenzisa izintambo ze-fiber optical, ukulahlekelwa okuphezulu kokuncishiswa kwezintambo ezinde kuyagwenywa.
Lokhu kwandisa ibanga elingaba khona phakathi kweyunithi eyi-remote kanye neyunithi enkulu lifike ku-20 km.I-subcarrier ifakwa endleleni yesignali ku-optical fiber ukuze isebenze njengesilawuli kude neshaneli yokuqondisa yazo zonke izisetshenziswa.Ngenxa yomqondo we-modular ukunwetshwa kamuva nokuthuthukiswa kungenzeka.Ukwehliswa kwemisebenzi yesistimu nakho kungahlinzekwa ngomthelela wezindleko eziphansi.
• Isithuthukisi samaseli asendlini esingabizi kakhulu
• Ukufakwa kalula ngenxa yobukhulu obuncane nokusebenza kwenzuzo ezenzakalelayo
• Ukuthembeka okuphezulu
Iziphindaphinda ezifunzwa nge-fibre zamasistimu omsakazo wezindlela ezimbili.Isixazululo se-fiber ye-Optical sokumboza kwangaphakathi kanye nokunwetshwa kobubanzi kumafrikhwensi we-VHF, UHF kanye ne-TETRA.
Lo mklamo usabalalise isistimu ye-antenna (i-DAS) yokwakha umsakazo ongenantambo.
Izinhlelo zokusebenza ezijwayelekile:
I-TETRA Fiber Optical Repeaters isetshenziswa kakhulu endaweni yasendlini nasezindaweni zangaphandle esezivele zinemicu ye-optic.Ukusetshenziswa kweziphindaphinda ze-Tetra Fiber Optical kuzoqeda ngokuphumelelayo izindawo eziyimpumputhe zesignali, kuthuthukise ikhwalithi yenethiwekhi, kuthuthukise isithombe sama-opharetha amaselula futhi kulethe inzuzo eyengeziwe.Zisetshenziswa kabanzi ezindaweni ezingezansi.
