Radio Frequency (RF) signals have been distributed over coaxial cables for decades, but for
today's mission critical government/military/intelligence operations that can be limiting,
expensive, and can pose a security risk. As a compelling alternative, fiber's main advantages for
RF signal distribution include extremely low transmission losses, reduced noise and
electromagnetic interference that bring improved security, performance, readiness, and
resilience.
USE CASE – SATELLITE GROUND STATIONS
With a fiber network and all-optical switching, organizations can now deploy highly secure solutions with capabilities that are not possible with traditional coax-based systems. In a typical satellite ground station deployment (Fig 1) there are significant benefits of an all fiber-based
approach that provide organizations with key advantages:
- Control rooms can be safely located further away from antennas
- Provisioning can be done remotely, automatically, and instantly - even from across the world
- Satellite dishes can be shared by different organizations
- Data can be easily rerouted around failures
