Fiber optic cable plays a starring role in helping integrators deploy some video systems, especially those with long distances from the camera to the headend. Fiber optic links allow for massive bandwidth capacities and immunity from Electro-Magnetic Interference (EMI) and Radio Frequency Interference (RFI). Security integrators can achieve cost savings by leveraging the vast amounts of unused optical fiber (“dark fiber”) that already exists in most large facilities, buildings and campuses.
