It's too short for communication. I think it's burst of particles that are released when spaceship goes out of warp.

16 day regular cycle is because it's regular transfer between two planets. Other FRBs are random because they are just random ships on random research routes.

Hah inevitably any type of FTL or even near light travel seems to inevitably also make an incredibly powerful weapon. This is even better because it doesn't require crashing the vessel into anything to destroy it.
