Fiber optic networks are currently deployed throughout an aircraft to allow communication between the various systems on-board. Fibers offer the advantage of reduced weight, higher bandwidth and immunity to electromagnetic interference over traditional coaxial cabling. Typically, one network carries digital data from one on-board system to another, while another takes analog data for electronic warfare applications received from an external source and sends it to a central on-board system (1). In order to reduce the complexity and maintenance of multiple fiber networks, it would be advantageous to use a single fiber network over which both types of signals could travel. Previous work has looked at combining both analog and digital signals over the same fiber (2, 3). However these demonstrations required the analog signal to operate at a frequency beyond that of the digital data. In this paper we demonstrate a system to transmit both analog and digital signals within the same frequency bands over the same fiber network with minimal degradation of either signal due to interference from the other.
