1550EA
1550EA TAXANAHA ITU DHAMAAN C-BAND rog-rogmi kara
Astaamaha
◆Tayada sare: tignoolajiyada cusub ee labajibbaaran ee asalka ah ee microwave, tignoolajiyada predistortion RF ceymis ku jira xaalada tayada CNR=53dB, nidaamku wuxuu heli karaa CTB.CSO ugu weyn.Tusmada SBS.
◆Dabacsanaan: tignoolajiyada modulator-ka ee modulator-ka dibadda ayaa caymisa waxqabadka CSO oo aad u wanaagsan, wanaajinaya awoodda ugu badan ee fiber indhaha, hel wareejinta fogaan dheer.SBS: 13-19, OMI, ITU hirarka dhererka la hagaajin karo, AGC/MGC la dooran karo, codso shabakado kala duwan.
◆Intuitive: Laysku waa qaybaha mishiinada ugu qaalisan, mishiinka ku qalabaysan microprocessor-ku wuxuu ilaaliyaa xaalada shaqada ee leysarka, daaqada LCD-ga waxay soo bandhigaysaa cabirrada hawlgalka.
Nooca Shabakadda: Dooro dammaanad-qaade ka-hortagga xaaladda-dhammaan si aad u buuxiso heerka qaranka oo aad ula jaan-qaado heerka SCTE HMS, waxay awood u siinaysaa la-socodka maamulka shabakadda.(Ku xidh nooca korantada nooca): ku dheji furaha aluminiumka ee nooca aluminiumka ah ee sahayda beddelka, waxay ka shaqayn kartaa 85 265Vac City Network Voltage, Iyo sidoo kale sahay koronto oo ikhtiyaari ah DC48V (boos ayaa loo baahan yahay);chassis qaboojinta xakamaynta heerkulka tooska ah.
