532/780nm Polarization Maintaining Fused WDM
The 532/780nm Polarization Maintaining Fused WDM is a high-performance passive wavelength division multiplexer designed for combining or separating 532nm and 780nm optical signals in polarization-maintaining fiber systems. Based on fused biconical taper (FBT) technology, this PM WDM provides low insertion loss, high isolation, and excellent polarization stability for demanding visible and near-infrared optical applications.
Manufactured using PM630 polarization-maintaining fiber, the device maintains the polarization state of transmitted signals while delivering high return loss and reliable long-term performance. With a compact package design and robust fiber construction, it is well suited for integration into OEM laser modules and advanced photonic systems.
The 532/780nm PM Fused WDM is widely used in spectroscopy, biomedical imaging, quantum optics, laser combining, fiber sensing, and scientific research applications where precise wavelength multiplexing and stable polarization control are essential.
