Waveguide Extensions/Accessories
FiberPlex WEB Brass Extension tubes for use with WGF series waveguides

Overview
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.

WEB tubes are made of brass, and can be installed in walls up to 6 inches (15.2 cm) thick for the WEB-6 or 12 inches (30.5 cm) thick for the WEB-12. They have external threads that match the WGF-6, WGF-461 and WGF-4, and require a WCN-6 Waveguide Coupling Nut (thread size 1-1/8 inch, 18 NEF) to attach them to the Waveguide Filter (WGF).

Note: If you are installing a WGF into a wall that is up to 2.51 inches (6.38 cm) thick, consider the Waveguide Extension Nut (WEN) which provides an extension solution that maintains the mathematically calculated dimensions of the waveguide while creating a flush-mounted solution. Or if you are installing a WGF into a wall that is up to 18 inches (45.7 cm) thick, consider the PVC Waveguide Extension Tube (WET).
