First time accepted submitter dkatana writes Having some type of fiber or high-speed cable connectivity is normal for many of us, but in most developing countries of the world and many areas of Europe, the US, and other developed countries, access to "super-fast" broadband networks is still a dream. This is creating another "digital divide." Not having the virtually unlimited bandwidth of all-fiber networks means that, for these populations, many activities are simply not possible. For example, broadband provided over all-fiber networks brings education, healthcare, and other social goods into the home through immersive, innovative applications and services that are impossible without it. Alternatives to fiber, such as cable (DOCSYS 3.0), are not enough, and they could be more expensive in the long run. The maximum speed a DOCSYS modem can achieve is 171/122 Mbit/s (using four channels), just a fraction the 273 Gbit/s (per channel) already reached on fiber.
