The WGF-461 was designed to meet MIL-461 EMC specifications by providing 100 dB attenuation for frequencies up to 40 GHz. It provides a means of bringing six pre-terminated fiber optic cables into a shielded enclosure while maintaining the enclosure’s radio frequency isolation integrity. The filter has a patented removable center plug, which is surrounded by six waveguide bores. When the center plug is removed, connectorized fiber optic cables can be inserted into the peripheral cable sized slots.
