Waveguide Feedthrough Filters

Waveguide feedthroughs are used to create a penetration through a shielded enclosure without violating the shielding characteristics of an enclosure.  These feedthroughs have a removable centre plug which allows pre-terminated fibre optic cables to be passed through the wall of a shielded enclosure.  Once the cables are through, the plug can be reinserted to achieve the desired isolation.  The bores are precision milled to allow a specific amount of attenuation at certain frequencies with the plug installed.
