Abstract
A passive optical anti-tamper system including one or more light pipes, one or more light detectors and an alarm. The light pipes each include an input end and an output end and are located within a chassis with the one or more light detectors. The one or more light detectors are optically coupled to the output ends of the one or more light pipes. The alarm is operable to transmit a tamper-event-warning signal if an increased light level is detected by at least one detector.
