1. The above specifications are for the device without connector, PM WDM device for dual axis operation. All parameters are tested at room temperature.
2. for devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower, ER will be 2dB lower. the power transmitted through the connector is less than 2W. the default connector key is aligned to the slow axis.
3. For high power applications >10W, we will use heat sink package, please contact RBWDM for details.
4. For pulsed applications, please be sure to inform us of the pulse energy and peak power.
5. 1XN PM DWDM modules are also available, please contact RBWDM.
