In the late 1990s, telecom providers and utilities initiated a wide-scale build-out of optical fiber networks in anticipation of explosive growth in the demand for network capacity. Their thinking at the time was that the existing copper infrastructure - originally put in place to handle relatively modest amounts of voice traffic - would be insufficient to handle the future bandwidth requirements of the Internet Age, which would grow at an exponential rate for the foreseeable future.
Enter wavelength-division multiplexing (WDM), a technology that, by combining different light signals at different wavelengths on a single optical fiber, multiplied the data-carrying capacity of optical fiber by a factor of ~100. Furthermore, high-bandwidth uses of the Internet - such as streaming video -...
