* Above specifications are for devices without the connectors.
* For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower, ER will be 2dB lower and optical power is only 1000mW.
 *The PM fiber and the connector key are aligned to the slow axis. And for F type, fast axis is blocked.
