TL;DR: In this article, the effect of polarization mode dispersion that an optical signal experiences as it propagates through an optical transmission fiber is compensated for at a receiver using a birefringent compensator, in which the compensator automatically and adaptively generates a level of differential time delay that substantially equals the optical signal experience, but of different sign, and, therefore, essentially cancels out the undesired delay.

TL;DR: In this article, an optical amplifier is adapted to cancel the Raman gain of an optical transmission path that degrades those optical signals occupying the low end of the bandwidth such that the power is transferred from the latter signals to the optical signals occupied by the signal components at the high end of bandwidth.

TL;DR: A detailed view of the research and development efforts that resulted in a lightwave transmission system that is now being used in backbone national networks in the United States is provided.

TL;DR: In this article, a 107Gb/s field trial was conducted on a traffic carrying longhaul LambdaXtreme® transport platform over an active 504-km Verizon route in Florida thus proving upgradeability to 100 G of the Alcatel-Lucent 50GHz spaced ULH DWDM system.

TL;DR: A 226 node, 128 channel Raman gain based DWDM system being deployed by Verizon GNI to create a nationwide automated optical network carrying 10 Gb/s traffic and offering 40 Gb-s traffic capability is presented.
