I would say not really. This pretty much only fits the exact use case for its specific niche need. E.g. operating in RF adverse/non-recoverable environments. Otherwise it's a waste. So technically it's still not "popular" in the sense of general popularity. You're not going to see your general drone pilot rushing to put fiber optic on thier drone. This also isn't a new concept. Its the same thing as wire-guided missiles that have been around since WWII.
