Note:

*Extinction ratio is guaranteed from 10 ~ 50°C.
1. The PM fiber and the connector key are aligned to the slow axis.
2. ER value applies to fiber ≤ 0.75m. Increased fiber length will decrease ER.
3. For each connector, IL will be 0.3dB higher, RL 5dB lower, and ER 2dB lower.

All values referenced are without connector.
