Tilmaanta alaabta

ZTX1800 waa nooc heer-sare ah oo wax-qabad heer sare ah oo 1550nm ah oo wax ka beddelaya qalabka wax lagu beddelo ee korontada ku shaqeeya oo wax-qabad sarreeya oo koronto ku beddelanaya. Dhammaan ilaha iftiinka unugga oo dhami waxay qaadanayaan xawaaraha cidhiidhiga ah, buuqa yar, mawjadaha joogtada ah ee loo yaqaan 'DFB laser', taas oo macquul u ah yareynta saameynta faafitaanka. Sababtoo ah qaadashada astaanta caalamiga ah ee qaybaha muhiimka ah iyo tikniyoolajiyadda xakamaynta nidaamka shirkadeena, tiknoolajiyada xakamaynta shabakadda SMNP, tilmaamayaasha waxqabadka mashiinka ayaa si buuxda u cabbiraya heerka qalabka la midka ah ee la soo dejiyo. Waxay ku siin kartaa sawirro tayo sare leh, dijitaal ama istiraatiijiyad dijitaal dijitaal ah oo loogu talagalay gudbinta masaafada dheer ee telefishanka iyo telefishanka xiriir.

Astaamaha

(1) Tayo sare: Tiknoolajiyada il laba-geesoodka ah ee microwave-ka iyo tiknoolajiyada horudhaca ah ee RF waxay hubineysaa in nidaamku heli karo bartilmaameedka ugu badan ee CTB, CSO, iyo SBS marka laga hadlayo waxqabadka wanaagsan ee CNR≥52dB.

(2) Dabacsanaanta: Marka la hubinayo nidaamka waxqabadka sare ee CSO, tiknoolajiyada wax ka beddelka wajiga ee qalabka wax lagu beddelo waxay sare u qaadaysaa awoodda muraayadaha ee fibaarka si loo helo gudbinta masaafada dheer, iyo marinka SBS ee la isku hagaajin karo, 13, 16,18dB, AGC / MGC qaabka la xusho, garoonka oo la hagaajiyay OMI wuxuu ka dhigayaa mid ku habboon gudbinta shabakadaha kala duwan.

(3) Aaminaad: 19 "1U rack istaandarka ah, oo lagu dhisay wax-qabad sare wax-qabad koronto laba-jibbaar ah, wuxuu ku shaqeyn karaa keydka 85 ~ 265Vac Network Network Voltage, MS-heerka is-beddelka tooska ah; jiifku qaboojinta xakamaynta heerkulka otomaatiga ah.

(4) Dareen: Modulator-ka dibadda iyo leysarka ayaa ah qaybaha mashiinka ugu qaalisan, mashiinka ku qalabeysan microprocessor wuxuu kormeeraa xaaladda shaqada ee qalabka dibadda iyo leysarka, daaqadda LCD ee guddiga ayaa soo bandhigaysa xuduudaha hawlgalka.

(5) Nooca shabakadda: Xulo dammaanad-wareejinta heerka-kormeerka Dhammaan-sheyga si aad ula kulanto heerka qaran oo aad ula jaanqaadi karto heerka SCTE HMS, waxay awood u siinaysaa awooda kormeerka maaraynta shabakadda.

(6) Awood koronto oo la qaadan karo: waxay qaadataa wax aluminium ah, furaha furaha PSU, la shaqee 86 ~ 265VAC, waxaa lagu beddeli karaa -48VDC si fudud.
