When using fiber optic cable to remote AN/TPN-24 ASR signals, what must the separation distance be less than between shelters?

In the context of using fiber optic cable to remotely transmit AN/TPN-24 ASR (Airport Surveillance Radar) signals, maintaining appropriate separation distances between shelters is critical to ensure signal integrity and system performance. The correct answer, which indicates a separation distance of 2.1 meters, is likely derived from standards and best practices related to minimizing signal degradation, electromagnetic interference, and environmental factors that may affect the fiber optic transmission.

The specified distance is established based on the characteristics of fiber optic cables, which can be sensitive to external influences. At distances greater than this threshold, the likelihood of potential issues such as signal loss or degradation increases, which can compromise the functionality of the radar system.

Adhering to the 2.1 meter separation ensures that the systems can operate effectively without interference, thereby maintaining reliable communication of the ASR signals. It is always advisable to follow such guidelines closely to maximize the performance and efficiency of electronic systems deployed in sensitive operations like air traffic control.
