Other Considerations
TEMPEST Support
TEMPEST is a US Government specification and NATO certification intended to protect valuable and mission
critical information from being intercepted through leaking emanations, including unintentional radio or
electrical signals, sounds, and vibrations. The protection efforts are also known as emission security (EMSEC),
which is a subset of communications security (COMSEC).
Several FiberPlex Technologies FOI units have a variant designated with a ‘T‐ST’ suffix, which has been
rigorously designed and tested to comply with TEMPEST requirements. These units can easily be visually
identified by their silver finish.
An RFI suppressed version of the PSQ‐4909 AC power supplies have been tested with the TEMPEST FOI units
and should be used with those units as part of a complete, certified TEMPEST solution. This version can be
ordered using an ‘R’ suffix after the model number (PSQ‐4909‐R).
When using TEMPEST rated FOI, much care must be taken in both the mating equipment and especially the
copper cabling used in such connection. In addition, the power supplies and/or chassis being uses must have
an ‘R’ suffix. For standalone applications, use a PSQ‐4909‐R (or the older PSQ‐4910‐R) power supply or for a
chassis mounted solution use either an RMC‐3101‐R or RMC‐2101‐R chassis. All the items in the system must
be TEMPEST compliant for the system to properly protect the information.
