980/1310nm Polarization Maintaining Fused WDM
The 980/1310nm Polarization Maintaining Fused WDM is a compact passive wavelength division multiplexer designed for combining or separating 980nm and 1310nm optical signals in polarization-maintaining fiber systems. Manufactured using fused biconical taper (FBT) technology, this PM WDM offers low insertion loss, high isolation, and stable polarization performance for telecom and laser applications.
Built with PM980 polarization-maintaining fiber, the device maintains the polarization state of transmitted light while providing excellent return loss and long-term optical stability. Its compact package design and reliable fiber structure make it suitable for OEM integration and demanding photonics environments.
The 980/1310nm PM Fused WDM is widely used in fiber amplifiers, laser systems, optical communication, fiber sensing, biomedical instrumentation, and scientific research applications requiring efficient wavelength multiplexing with stable polarization control.
