Dimensions (mm)

 φ5.5 × L35(P1) (only for bare fiber or 900um loose tube)
L90*W20*H9.5（ABS）(P2) (only for 3mm or 2mm cable)

*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.
*The transmission optical path of A type is different from B type:Type A: 1 -> 2, 2 -> 3, 3 -> 4; Type B: 1 -> 2, 2 -> 3, 3 -> 4;4->1
