Thankfully, the gathering also discussed some unconventional ways of getting around this seemingly insurmountable barrier. One technique would ramp up the power in fiber and use calculations to reconstruct a usable signal on the other end, while another would involve fibers with multiple cores that offer much more bandwidth in a similar space. The challenge is putting these theories into practice before it's too late. As with processors, there's no guarantee that big breakthroughs will come in the nick of time.
