Many of the assumptions in this article appears incorrect.<p>>> How do you keep the Internet from reaching “the limit”? The most obvious way is to increase bandwidth by laying more fiber.<p>There is no shortage of installed fiber. The majority of installed optical cables have multiple fibers (e.g. 12, 48, 96 etc), the majority of which are usually dark. Only 2 (or even 1) fibers in a cable are needed to carry an Ethernet network. It is (generally) not that we need to lay more fiber, it is (generally) that we need to light more fibers in a cable by provisioning additional electronics at each end of the cable - assuming the existing optical fiber(s) are running anywhere near the nonlinear Shannon limit.
