ETS-Lindgren's Waveguide Filters are designed to provide a means of bringing fiber optic cables into a shielded enclosure while maintaining the enclosure's radio frequency isolation integrity.
These filters have a removable center plug, surrounded by either six or twelve waveguide bores. When the center plug is removed, connectorized cables can be inserted into the peripheral cable-sized slots. Additionally, the waveguide bore diameter-to-length ratio have been optimized to ensure high attenuation.
