980/1030nm Polarization Maintaining Fused WDM
The 980/1030nm Polarization Maintaining Fused WDM is a compact passive wavelength division multiplexer designed for combining or separating 980nm and 1030nm optical signals in polarization-maintaining fiber systems. Manufactured using fused biconical taper (FBT) technology, this PM WDM provides low insertion loss, stable polarization performance, and reliable wavelength isolation for high-precision optical applications.
Built with PM980 polarization-maintaining fiber, the device preserves the polarization state of transmitted light while offering low back reflection and excellent optical stability. With low insertion loss and compact packaging, it is ideal for integration into fiber laser systems, amplifier modules, and OEM photonics equipment.
The 980/1030nm PM Fused WDM is widely used in fiber lasers, biomedical instrumentation, spectroscopy, optical sensing, ultrafast laser systems, and scientific research applications requiring efficient wavelength multiplexing with stable polarization control.
