*Above specifications are
for device without connector. |
|
|
| |
*For devices with
connectors, IL will be 0.3dB higher, RL will be 5dB lower, and ER will be 2dB
lower. |
|
|
| |
*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. |
