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