OR719
OR719 Bannaanka Laba-jiho ee Afarta Wax soo saar ee Qaadaha indhaha
Astaamaha
◆Jawaab sare oo tuubada beddelka koronto-dhaliyaha ee PIN.
◆ Wareegga ogaanshaha saxda ah wuxuu si sax ah u soo bandhigi karaa awoodda wax soo saarka iyada oo loo marayo nalka LED ama tuubada dhijitaalka ah.
◆ Kor u qaad naqshadaynta wareegga, SMT + module amplifier-ka caadiga ah ee gudbinta signalka sawir-qaadista wareegga waa faseexnimo.
◆Power double saarka, faa'iido sare, qalloocan hooseeya, qaab-dhismeedka is haysta, rakibaadda ku habboon, waa qalabka doorashada koowaad ee FTTB CATV network.
◆ Farsamada xakamaynta indhaha ee AGC ee ugu fiican, marka kala duwanaanta awoodda indhaha ee wax gelinta ay tahay -7 ~ ＋2dBm, heerka wax soo saarka, CTB iyo CSO asal ahaan isma beddelin.
