1X2 Polarization Maintaining DWDM

The Polarization Maintaining Filter DWDM is characterized with low IL, high return loss, high extinction ratio and excellent environmental stability and reliability. They are ideal for polarization maintaining fiber amplifiers, DWDM network, and high-speed communication system and instrumentation applications.

Above specifications are for device without connector, and the PM WDM device is both axis working. All parameters are tested at room temperature.
For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. Power transmits through the connector less than 2W. The default connector key is aligned to slow axis.
For >10W high power applications, we will use heat sink package, contact DK Photonics for details.
If there is pulse application, please be sure to inform us of pulse energy and peak power.
1XN PM DWDM module is also available, please contact DKP.
