*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.
*For F type: slow axis working, fast axis is blocked; For type B : both axis is working; For S type:fast axis working, slow axis is blocked.
