Traditionally, A&D communication infrastructure is wireless and copper dominant. There’s a wealth of in-house RF expertise, while photonics R&D within A&D sector is on the rise only recently. Ultra-high-resolution aerial and satellite imaging, large amount of data from sensor networks, real-time simulation and computation needs, secure communication, on-board high-speed Internet and entertainment are some of the reasons where existing RF and copper-based infrastructure is no longer enough. Optical fibers offer much higher bandwidth, provide significant weight-savings (a critical need in aerospace), require much lower maintenance, provide higher durability and reliability. Photons travel much faster than electrons, which is why latency in fiber-optics is minimally low. In Figure 1 we see a comparison of copper and optical fiber. Unlike copper-based systems, fiber-optics consumes less energy, generates no heat, offers excellent protection against fire, and provides immunity from RF-interference and eavesdropping. In addition, the wireless RF-spectrum is scarce and heavily regulated, while the photonic spectrum is vast and free from regulatory or compliance obligations.
