Internal Research & Development

PDA Engineering devotes substantial resources to advanced concepts development (and patent holders) in a range of technologies to move solutions up the technology readiness level ladder. 

  • Ultra-high-speed (40G and faster) network appliances for unique data distribution solutions

  • Photonics specializing in dynamic Wave Division Multiplexing used to upgrade existing fiber networks to extreme new capacities

  • Power over fiber as a means to simplify architectures and installations in industrial and military environments

  • Advanced propulsion, automated navigation, and autonomous decision-making for small form factor drone devices operating in GPS-denied environments

  • Novel situational awareness solutions requiring rapid deployment (sub 2 seconds) and low observable characteristics


The IR&D department also maintains a deep understanding of cyber resilience, producing electronic and computational designs intended for installation in sensitive locations.

Wave Division Multiplexing (WDM)

PDA Engineering's Wave Division Multiplexing allows all of the different signals that traditionally required a separate cable to be carried on a single fiber optic cable. WDM puts multiple signals on the same fiber but keeps them separate by modulating them on different frequencies, similar to how radio stations operate. The capacity of WDM can be calculated by assuming 72 conductors per cable, four bands per conductor, 96 ITU channels per band, and 50 Gbits of data per channel. That equals 1,382,400 Gbits on a single fiber cable. And because WDM is not point-to-point, additional cables are not necessary for adding capacity and equipment.

The Solution

Traditional cables are point-to-point, meaning in order to add equipment or capacity, additional cables are needed. As the cable number increases, so does the complexity, installation effort, testing, weight, space taken, and time and materials. ​In many military or other harsh and highly regulated environments, the ever-increasing number of cables can lead to issues that are detrimental to performance.

The Problem


Thunderstorm is PDA Engineering's evolution of the commercial Thunderbolt technology, which transmits multiple high-capacity data formats simultaneously but is length-limited and can only bridge a single computer and a device chain. Thunderstorm extends this technology to arbitrary distances and enables dynamic routing, moving Thunderbolt from a point-to-point solution to a true mesh topology with real-time switching and routing capabilities. 

Deep Fake Detection/Mitigation

Our Deep Fake Detection system is a capability within the Optical Video Coupler (OVC) product line. While OVCs provide real-time video/audio/HMI/discrete data transports, this extension can detect and flag changes made to both live and previously recorded data sets, specifically those generated by systems attempting to modify the content of a given stream.

Low Data Rate Voice (LDR)

Our patent pending LDR system is intended for establishing voice communications over exceptionally low data rate links, for example underwater or in communications-denied environments. The protocol used for LDR is lightweight and designed to be implemented in low power, wearable electronic assemblies.

Underwater Unmanned Vehicle (UUV)

PDA Engineering's UUV is a small form factor autonomous vehicle that leverages the latest in artificial intelligence and sensor systems to create true vehicle independence. Mission profiles can remain at a high level while the UUV solves the problem of navigation, data gathering, and signal analysis on its own.
