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@qoptronics.com     咨询QQ:  3191209539 (欢迎咨询) 公司固话：021-64778883
