The Bandpass Filter is a micro optics device based on environmentally stable thin film filter technology. It is widely applied to blocking the unwanted noise signals in EDFA and fiber pump laser systems, to get the signals needed. The components are characterized with high isolation, low insertion loss, high return loss, excellent environmental stability and high power handling capability.大宝娱乐רҵÑб¬·¢²úPM BPF,¹¤Òµ¼¶PM VOA,ÊÇÒ»¸öרҵµÄPM BPF³§¼Ò,ÓкܺõÄPM BPF¼ÛÇ®¡£大宝娱乐רҵÑб¬·¢²úµÄPM BPFÆÕ±éÓ¦ÓÃÓÚº½Ìì¡¢º½¿Õ¡¢µçÁ¦¡¢Ìú·¡¢Ò½ÁÆ¡¢½»Í¨¡¢Í¨Ñ¶¡¢µÈ¸÷´óÁìÓò¡£
