高功率微光学型保偏耦合器 High Power PM Filter Coupler 1x2(2x2)     PDF资料下载 Applications: Features: EDFA Fiber Optical Instrument Power Monitoring Fiber Sensor Low Insertion Loss High Extinction Ratio、High Isolation、High Power High Stability and Reliability     Parameter Unit Specification Part No. - L-P-FT-PF-C Type. - 1x2 2x2 Wavelength nm 1310,1550 980,1064 1310,1550 980,1064 Operating Bandwidth nm ±40 ±20 ±40 ±20 Excess Loss dB <0.7 <0.8 <1.0 <1.2 Uniformity(only for 50/50) dB <0.4 <0.5 <0.6 <0.8 Tap Ratio % 1±0.2%,2±0.4%,5±1%,10%,20%,30%,50% ER type B(both of axis working) - >20 >20 >18 >18 ER type F(fast axis blocked) - >22 >22 >22 >20 Return Loss dB >50 Power handling CW W 1,2,3,5 Fiber type - PM1310,PM1550,PM980 Operating Temperature °C -5~+70 Storage Temperature °C -40~+85 Dimensions mm φ5.5 × L35 or L90*W20*H9.5 Above specifications are for devices without connector. For devices with connectors, IL will be 0.3 dB higher and RL will be 5 dB lower . and ER will be 2dB lower.The PM fiber and the connector key are aligned to the slow axis. And for F type, fast axis is blocked.                     联系人： Michael 李       (欢迎来电) 工作邮箱:   michael@     咨询QQ:  3191209539 (欢迎咨询) 公司固话：021-64778883
