Nonlinear optical effects
These are cross interactions between light and matter which occur when extremely powerful light passes through optical fiber or other material. The challenge in this instance is what is called self-phase modulation, in which the phase of the light wave changes over an interval in response to the light's brief intensity.
 Nonlinear compensation technology
A technology making it possible to counteract the complex waveform distortion that accumulates from the nonlinear effect occurring at every point on a long-distance fiber-optic line.
 DP-QPSK: Dual-Polarization Quadrature Phase Shift-Keying
DP-QPSK is a modulation method that is becoming the industry-wide standard for optical transmission systems running at speeds of 100 Gbps.
 RZ: Return-to-Zero
In optical modulation, a method of pulse carving that temporarily drops the optical power at the moment between symbols, returning it to zero.
