very clever idea!

if you know how OTDR works, location is known by high speed modulation and high speed sampling components, which means high costs, if you want to achieve higher resolution. Usually the laser pusle will be in the level of nano seconds.

what's being introduced in the article is using multiple fibers with coded location info. therefore no need to have sophisticated OTDRA-like equipment to get the location info.

not sure if my understanding is right, but good job: from a simple idea to sophisticated design, optimization and even commercialization.congrats.
