1) The PM fiber and the connector key are aligned to the slow axis
2) The ER is for fiber ≤ 0.75m. Increase fiber length can decrease the ER.
3) For devices with connectors, insertion loss will be 0.3dB higher, return loss will be 5dB lower, and extinction ratio will be 2dB lower
*The diameter indicates outer diameter (OD) of lens.
All values referenced are without connector.
