980/1550nm Polarization Maintaining WDM Filter

FIBERWDM can supply 980/1550nm Polarization Maintaining WDM Filter (PM filter), the PM filter multiplexes PM signals and maintains the output polarization with high extinction ratio using advanced micro-optic filter technology. All input and output fibers are polarization maintaining.

This product can also be used to multiplex other wavelengths. including 980/1030nm (pulsed laser applications) and 1064/1550nm (Erbium-Ytterbium pumping). Low power (300 mW, 500 mW) and high power ( up to 20W) handling are available.

It can also be provided with a PM isolator integrated in the same package. They are great used in polarization maintaining fiber amplifiers, fiber lasers, and high speed communication system and instrumentation applications.

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. For >10W high power applications, we will use heat sink package, contact FIBERWDM for details.

4. If there is pulse application, please be sure to inform us of pulse energy and peak power.

5. If need other request, please contact FIBERWDM.
