Product Details
Components of the Polarization Maintaining CWDM filter involve a wave-guide structure where optical signals first enter through multiple incident ports prior to transmission. This wave-guide structure intelligently directs the optical signal to the appropriate output port, based on its specific wavelength. At the wave-guide output port, a filter is positioned to eliminate unwanted wavelengths, ensuring only signals of the desired wavelengths are retained. The PM CWDM filter component is ideally suited for applications in CWDM networks, high-speed communication systems, and instrumentation.

1. Above specifications are for device without connector, and the PM WDM device is both axis working. All parameters are tested at room temperature.
2. 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.
3. If there is pulse application, please be sure to inform us of pulse energy and peak power.
