*Above specifications are for devices without the connectors.
*For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower, ER will be 2dB lower, optical power is only 1W.
*The PM fiber and the connector key are aligned to the slow axis. 
*For F type, fast axis is blocked, the input must be linear polarized light, and the input polarization must be aligned properly.
