Inkqubo ye-Fiber Optic Cellular Repeaters (FOR) yenzelwe ukusombulula iingxaki zesignali yeselula ebuthathaka kwindawo ekude ne-BTS (i-Base Transceiver Station) kwaye ine-fiber optic cable network network underground.
Sombulula naziphi na iindawo ekunzima ukufikelela kuzo!
Yonke inkqubo FOR inamacandelo amabini: iYunithi yoMnikeli kunye neYunithi ekude.Bahambisa ngokucacileyo kwaye bakhulise isignali engenazingcingo phakathi kwe-BTS (iSikhululo se-Base Transceiver) kunye neemobiles ngeentambo zefiber optic.
Iyunithi yoMnikeli ibamba umqondiso we-BTS nge-coupler ethe ngqo evaliweyo kwi-BTS (okanye nge-open air transmission ye-RF nge-Donor Antenna), emva koko iyiguqule ibe ngumqondiso we-optic kwaye idlulisele isignali ekhulisiwe kwiYunithi ekude ngeentambo ze-fiber optic.IYunithi ekude iya kuyiguqulela kwakhona isignali ye-optic ibe ngumqondiso we-RF kwaye ibonelele ngophawu kwiindawo apho unxibelelwano lwenethiwekhi lunganelanga.Kwaye isignali yeselula nayo ikhulisiwe kwaye idluliselwe kwi-BTS ngendlela echaseneyo.
KingtoneIFiber Optic Repeaters inkqubo yenzelwe ukusombulula iingxaki zesiginali ephathwayo ebuthathaka, enexabiso eliphantsi kakhulu kunokuseta iSikhululo esitsha seSiseko (BTS).Ukusebenza okungundoqo kwe-RF Repeaters system: Kwikhonkco elisezantsi, iimpawu ezivela kwi-BTS zondliwa kwiYunithi yoMnikeli (DOU), i-DOU emva koko iguqule isignali ye-RF kwisignali ye-laser emva koko isondlo kwi-fiber ukuze idlulisele kwi-Remote Unit (ROU).I-RU ke uguqule isiginali yelaser ibe ngumqondiso weRF, kwaye usebenzise iAmplifaya yaMandla ukukhulisa amandla aphezulu kwi-IBS okanye i-eriyali yokhuselo.Kwikhonkco eliphezulu, Ngaba yinkqubo ebuyela umva, imiqondiso evela kumsebenzisi weselula ifakwa kwi-DOU's MS port.Nge-duplexer, isiginali yandiswa ngesandisi-lizwi esisezantsi sokuphucula amandla omqondiso.Emva koko imiqondiso ifakwa kwimodyuli ye-fiber optical ye-RF emva koko iguqulelwe kwiimpawu ze-laser, emva koko isiginali yelaser idluliselwe kwi-DOU, isiginali ye-laser esuka kwi-ROU iguqulelwa kwisiginali ye-RF nge-RF optical transceiver.Emva koko imiqondiso yeRF iye yandiswa ukuya kwiimpawu zamandla ezongeziweyo ezifakwe kwi-BTS.
Iimbonakalo
- I-aluminium-alloy casing inokumelana okuphezulu nothuli, amanzi kunye nokubola;
- I-antenna ye-Omni-directional coverage inokwamkelwa ukwandisa ukugubungela ngaphezulu;
- Ukwamkela imodyuli ye-WDM (i-Wavelength Division Multiplexing) ukuqonda ukuhanjiswa komgama omde;
- Uzinzo nophuculweyo umgangatho wothumelo lwesignali;
- IYunithi yoMnikeli enye inokuxhasa ukuya kuthi ga kwiiYunithi ezi-4 ezikude ukwandisa ukusetyenziswa kwentambo yefiber optic;
- Izibuko ze-RS-232 zibonelela ngamakhonkco kwincwadana yokubhala yolawulo lwasekhaya kunye nemodem engenazingcingo eyakhelweyo ukunxibelelana ne-NMS (iNkqubo yoLawulo lweNethiwekhi) enokubeka esweni ukude imo yokusebenza yalowo uphindayo kwaye ikhuphele iiparamitha zokusebenza kulowo uphindayo.
