Bandwidth-hungry applications are driving adoption of fiber-based “last-mile” connections—and raising the challenge of moving access-network capacity to the next level.
For years, the global Internet’s “last mile”—the access networks that connected end users to the central offices (COs) of telecom operators—represented the key bottleneck in end-to-end network infrastructures. That has begun to change with the widespread adoption of broadband access technologies, including digital subscriber line (DSL), cable modem and, most recently, fiber-to-the-home (FTTH). These technologies have helped enable the Internet we know and use today, and have led to the proliferation of applications such as cloud computing, the “Internet of Things” and video streaming.
