PM Filter Couplers

PM Filter Couplers (Polarization Maintaining Filter Couplers) are optical devices used to filter and couple polarized optical signals in optical systems. They combine the properties of polarization maintaining technology and filter devices to provide precise control and management of optical signals over a specific wavelength range.

These devices typically consist of polarization beam splitters, filters, and polarization combiners. They can select a specific wavelength range as required, and filter and couple the input polarized optical signal according to the selected wavelength range to output an optical signal that meets specific needs.
