PA 719
OR719 Panja Bi-directional Zinayi Zotulutsa Optical Receiver
Mawonekedwe
◆Kuyankha kwakukulu Pin yojambula zithunzi zosinthira chubu.
◆ Dera lodziwika bwino limatha kuwonetsa nthawi yeniyeni mphamvu yotulutsa kudzera mu nyali ya LED kapena chubu cha digito molondola.
◆ Konzani kamangidwe ka dera, SMT + module amplifier classic circuit photoelectricity signal transmission ndi bwino kwambiri.
◆ Mphamvu zotulutsa kawiri, kupindula kwakukulu, kusokoneza pang'ono, kamangidwe kakang'ono, kuyika kosavuta, ndicho chida choyamba chosankha cha FTTB CATV network.
◆Njira zabwino kwambiri zowongolera za AGC, pomwe mphamvu yamagetsi yolowera ndi -7~＋2dBm, mulingo wotulutsa, CTB ndi CSO sizinasinthe.
