*Above specifications are for devices without the connectors.  
*For devices with connectors, IL will be 0.3dB higher, RL will be 5dB 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.  
*The transmission optical path of A type is different from B type:Type A: 1 -> 2, 2 -> 3, 3 -> 4; Type B: 1 -> 2, 2 -> 3, 3 -> 4;4->1
