What are 1.0μm PM Components? | A Brief Guide
In the fiber optics, PM doesn't stand for Particulate Matter. Here, PM means Polarization Maintaining. This wavelength sits in a specific window of the optical spectrum, and it has some unique characteristics that make it useful for different applications. The 1.0 micrometer (or 1000 nanometer) wavelength region is a bit less popular than 1310nm or
