Description

ETS-Lindgren’s waveguide filters are designed to provide a means of bringing fibre optic cables into a shielded enclosure while maintaining the enclosures radio frequency isolation integrity.

The filter has a removable centre plug which is surrounded by either six or twelve waveguide bores. When the centre plug is removed, connectorized cables can be inserted into the peripheral cable-sized slots. The waveguide bore diameter-to-length ratios have been optimized to ensure high attenuation.
