1 Introduction
The Wireless Optic Fiber Seal (WOFS) has been developed to support the Global Threat
Reduction Initiative mission of securing radioactive material. Once installed, WOFS will prevent
unmonitored access to essential equipment or materials. This guide provides installation and
maintenance instructions for the WOFS system.
2 Concept of Operation
The WOFS system consists of a WOFS Receiver (see Figure 1) in wireless communication with
a WOFS Transmitter (see Figure 2). The Transmitter is connected to a loop of fiber optic cable
that will be wrapped around or through the object to be sealed. Sealed objects can include
equipment racks, panels, doors, or drawers.
If the fiber optic cable is broken, WOFS will trigger an alarm indicating that the seal has been
compromised. The WOFS is also equipped with a security features to resist attempts to “spoof”
the optical signal.
