This isn't the kind of thing that we're going to see in home internet for a long time. The newest WiFi standard is only 10Gbps at best, and routers and wired standards aren't affordable over 10Gbps yet either for home use. For internet connections, there are currently already consumer standards that can do 10Gbps symmetric (like NG-PON2) which hopefully we see being deployed more widely soon. Even in 15 years I would be surprised if the high-end of available speeds for home connections are more than 2-5x that (Of course, companies that can pay for dedicated links can already get 100Gbps+ today). The technology in the article, if commercially practical, would first go in to carrier networks and the larger enterprise market for backhaul transit links in the next few years, then over time filter down to general enterprise networking. Even if transit providers upgrade, it wouldn't actually be a noticeable change, because they can already do this kind of link, just with a rack with dozens of laser modules that are optically multiplexed together. This does that in a single chip which would reduce cost a lot.
