532/635nm Polarization Maintaining Fused WDM
The 532/635nm Polarization Maintaining Fused WDM is a compact passive wavelength division multiplexer designed for combining or separating 532nm and 635nm optical signals in polarization-maintaining fiber systems. Utilizing fused biconical taper (FBT) technology, this PM WDM delivers low insertion loss, high isolation, and stable polarization performance for visible wavelength applications.
Manufactured with PM460 polarization-maintaining fiber, the device preserves the polarization state of the optical signal while providing excellent return loss and reliable long-term stability. Its compact package and robust fiber structure make it suitable for OEM integration and precision photonics systems.
The 532/635nm PM Fused WDM is widely used in laser systems, spectroscopy, biomedical instrumentation, fiber optic sensing, quantum optics, and scientific research applications where stable polarization and efficient visible wavelength multiplexing are required.
