Note:

*Above specifications are for device without connector.

*For devices with connectors, IL will be 0.3dB higher (0.5dB higher for 1064nm), ER will be 2dB lower, and RL will be 5dB lower.

*The PM fiber and the connector key are aligned to the slow axis.

**Absolute delay at 0ps setting measured to the edge of the enclosure (excluding caps, boots, and Pigtails).
