1310/1550nm Polarization Maintaining Fused WDM
The 1310/1550nm Polarization Maintaining Fused WDM is a compact passive wavelength division multiplexer designed for combining or separating 1310nm and 1550nm optical signals in polarization-maintaining fiber systems. Utilizing fused biconical taper (FBT) technology, this PM WDM provides low insertion loss, stable polarization performance, and reliable wavelength isolation for telecom and photonics applications.
Constructed with PM1300 polarization-maintaining fiber, the device maintains the polarization state of transmitted light while ensuring low back reflection and excellent optical stability. Its compact package and robust structure make it ideal for integration into optical communication modules and OEM photonic systems.
The 1310/1550nm PM Fused WDM is widely used in optical communication networks, fiber amplifiers, fiber sensing, biomedical instrumentation, laser systems, and scientific research applications requiring efficient wavelength multiplexing with stable polarization control.
