* If tap port coupling ratio is 5%, ER will be 2dB lower; for 1% tap port, ER is out of concern

*Above specifications are for device without connector.

*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 fast axis is blocked.
