980/1064nm Polarization Maintaining Fused WDM
The 980/1064nm Polarization Maintaining Fused WDM is a high-performance passive wavelength division multiplexer designed for combining or separating 980nm and 1064nm 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 demanding laser and photonics applications.
Constructed with PM980 polarization-maintaining fiber, the device maintains the polarization state of transmitted light while ensuring low back reflection and excellent long-term optical stability. Its compact package and robust structure make it suitable for integration into fiber laser modules, amplifier systems, and OEM photonic equipment.
The 980/1064nm PM Fused WDM is widely used in fiber lasers, ultrafast laser systems, spectroscopy, biomedical instrumentation, optical sensing, and scientific research applications requiring precise wavelength multiplexing with stable polarization control.
