* The specifications above are for device without connector.
* IL is 0.3 dB higher, RL is 5 dB lower, and ER is 2 dB lower for each connector added.
* The transmission optical path of A type is different from B type: A type: 1 -> 2, 2 -> 3, 3 -> 4; B type: 1 -> 2, 2 -> 3, 3 -> 4, 4 -> 1.
* The PM fiber and the key are aligned to the slow axis and fast axis is blocked.
