The author discusses the history of telecommunication networks and the development of fiber networks.

Optical networking technologies have evolved significantly over the last few years: 100G coherent has been commercialized; flexibility in data rate, frequency grid and modulation format is a hotly

Summary form only given. DWDM technology has emerged as the leading solution for high-speed transmission to dramatically change the underlying characteristics of backbone networks.

Wavelength-division multiplexing (WDM) has been the workhorse of data networks, accommodating exponential traffic growth for two decades.

Summary form only given. Progress in optical networks is driven by the shift from voice messaging to data communications and an exponential growth in capacity demands.

Driven by increased high-bandwidth traffic, including video, the reduction in the last mile bottleneck resulting from ubiquitous DSL and growing fiber-to-the-home connections and an increasing glob

Optical performance monitoring is demonstrated using the nonlinear response of a semiconductor optical amplifier (SOA).

Optical performance monitoring is demonstrated using the nonlinear response of a semiconductor optical amplifier.

Constellation diagrams of the electric field of optical sources are directly measured using linear optical sampling.

Nonlinearity induced phase noise has become a major obstacle in long-haul coherent fiber-optic communication systems. It has been shown to be signal dependent and hence correlated over time.
