FiberPlex WEN-6 Waveguide extension nuts for WGF series waveguides

FiberPlex Waveguide Extension Nuts (WEN) for WGF series waveguide filters. The WEN-6 provides a neat, flush-mounted solution that accommodates walls up to 2.51 inches (6.38 cm) thick.

FiberPlex WGF series of waveguide filters provide a way of bringing pre-terminated fiber optic cables into a shielded enclosure while maintaining the enclosure's radio frequency isolation integrity. The diameter and length of the bore are precisely calculated to provide a measured attenuation at a specific cutoff frequency. This works extremely well, but occasionally the wall of the shielded enclosure, SCIF, or chamber that needs to be penetrated is thicker than the calculated length of the waveguide filter.

The WEN-6 solves this problem in walls that are up to 2.51 inches (6.38 cm) thick by providing an extension solution that maintains the mathematically calculated dimensions of the waveguide while creating a flush-mounted solution as shown in the video below.

Note: If you are installing a WGF into a wall that is up to 12 inches (30.5 cm) thick, consider the Brass Waveguide Extension Tube (WEB) and Waveguide Coupling Nut (WCN) or if you are installing into a wall that is up to 18 inches (45.7 cm) thick, consider the PVC Waveguide Extension Tube (WET).

The WEN is typically installed in SCIF or TEMPEST enclosures, but they are also ideal for applications such as these:
  • EMC Testing
  • RF Testing
  • Manufacturing
  • MRI / Medical
  • Anechoic Chambers
Note: The WEN is available in custom lengths, please call +1 301 975 1000 for details.
