OR719
OR719 Waho-rua-a-waho E wha Putanga Putanga Kaiwhiwhi Optical
Ngā āhuatanga
◆Ko te ngongo whakawhiti whakaahua hiko teitei o te PIN.
◆Precision detection circuit can real-time te whakaatu i te mana whakaputa ma te rama rama, ngongo mamati ranei.
◆Whakapaihia te hoahoa ara iahiko, SMT + module amplifier matarohia iahiko photoelectricity tuku tohu he pai ake.
◆Power rua putanga, hua nui, distortion iti, hanganga kiato, tāutanga watea, ko te taputapu tuatahi-kōwhiringa o FTTB CATV whatunga.
◆Tikanga whakahaere AGC whatu pai, ina ko te awhe mana whatu whakauru -7~＋2dBm, ko te taumata whakaputa, CTB me CSO kaore i rereke.
