Phase Modulation Techniques for On-Off Keying: Boosting Transmission Capacity in Optical Fibres - Softcover

Inhaltsangabe

The production and exchange of information drive muchof today's economy. This information exchange takesplace more and more at a global level, so it becomescrucial to be able to transmit ever larger amounts ofinformation over very long optical-fibre transmissionlinks. At the same time, the sobering up after theburst of the dot-com bubble in 2000-2001 has madecost a major consideration in any upgrading solution.This translates into the need for modulationtechniques that allow for the transmission of highbit rates over large distances at minimum cost. Thisbook presents three phase-modulation techniques thatallow the upgrade of existing transmission links tohigher bit rates using cost-effective On-Off keyingand direct detection. This is achieved thanks to thesuppression of intra-channel non-linear effects, suchas IFWM which become a major impairment for bit ratesof 40 Gb/s and above. The techniques are examinedanalytically, tested in numerical simulations, andverified in transmission experiments.
