General Details

FOCONEC produces FABP-ST/FCSX Blank Plug to cover hole positions with no ST or FC Simplex Adapter installed on fiber panels.

Sometimes, not all ST or FC adapter positions in fiber panels immediately used but need to leave for future fiber network expansion. To ensure a tidy and professional fiber cable installation and maintenance, we need blank inserts or plugs to cover the hole positions.

This fiber optic blank plug/insert is suitable for covering ST simplex adapter or FC simplex adapter(small D type) hole positions on rack/wall mount fiber patch panels, enclosures, distribution hubs, terminal box, LIU, etc.

It is very easy to plug, and removed for further fiber optic adapter installation.

Our blanking plugs are made of PC in black color, and the customized color is available as per request.
