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, for B type,both of axis working
