Waveguide Overview

Model #: WGF Series

WGF-6

The WGF-6 accepts up to six pre-terminated fiber optic cables with attached connectors. It is designed to provide a means of bringing 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.

WGF-12

The WGF-12 has a 27 GHz cutoff with twelve bores to accept pre-terminated fiber optic cables with attached connectors.

WGF-2550

The WGF-2550 has a 31.4 GHz cutoff and accepts up to six fiber optic cables and is sized to fit holes previously made for DB-25 connectors. It provides a means of bringing fiber optic cables into a shielded enclosure while maintaining the enclosure’s radio frequency isolation integrity.
