Netflix movie available for 2 days!!! Hummingbird Project
"the hummingbird project" People install a straight optical fiber between New York and the Kansas electronic exchange, in order to accelerate transactions, reducing the delay from 17 to 16 milliseconds. Relevance to me? My invention, an isotope modified optical fiber, https://www.freepatentsonline.com/9459401.html will be about 5.6% faster than ordinary germania-doped silica fiber, and thus would reduce the transit time by about a millisecond. In addition, according to the movie, each regenerator slows the signal by 20 microseconds. My fiber should have a loss of about 0.001 decibels/kilometer, which means that no regenerators nor amplifiers should be necessary, this saving hundreds more microseconds.
It could be faster if they just went RF. But since you don't have a patent on that, but you could, your next bet is to hit up all the HFT firms, international finance, etc. I'll take 5% for the nudge ;)

Ordinary quartz fibers have an index of refraction of about 1.42 at 1550 nanometer wavelength.My isotope-modified fibers should have an index of refraction 5.6% smaller, so the signal should go 5.6% faster.However, Starlink's system may beat both these systems, as it is low-earth-orbit.The 'horizon' of a satellite with an altitude of about 1 million feet (200 miles) is about 1230 miles.So, it is conceivable that such a satellite could be (temporarily) positioned between Kansas City and New York City to allow faster connection. Alternatively, if Starlink's satellites had satellire-to-satellite communication, such connections might be more regular and not discontinuous.

Some of problem is hopcount... the RF-electro-RF and optical-electro-optical conversions between domains at the repeaters takes time. Such that one sat hop could indeed be faster... tradeoffs are sync and tracking of low flying birds vs geostationary delay distance. Today's subsea are using doped optical pump amps but still needs regen to avoid distance goo. HFT need reliable, low latency, non corrupt... trade ticks not necessarily high bandwidth movies. Worth a look to see if they ever used zero hop ELF RF. And if anyone has any legit outlook on quantum-RF.
