Coherent Optics is used to increase the throughput capacity of fiber, and is one of the methods that will be used by CableLabs in their 10G initiative with Full Duplex Coherent Optics. In this broadcast we discuss what coherent optics is, and compare of some signal modulation techniques including Phase Modulation.

Hi guys, I think you are wrong: in the animation of the phase modulation the blue signal is the signal that carries information to be transmitted and the yellow one represents the carrier signal. The formular consequently shows f1 as the carrier frequency and f2 as the information signal frequqency. In coherent transmission f1 is as high as 200THz whereas f1 is up to around 100GHz these days.

Martin, thanks for pointing out that error in our reference to the phase modulation animation and your insight there.
